Industrial panel PC - guide and offer
Industrial panel PCs (Panel PCs) are now one of the cornerstones of modern industrial installations. By combining the display and the computing unit into a single, rugged enclosure, they are ideally suited for use as machine HMI panels, operator terminals, quality control stations, panels for SCADA/BMS systems, and self-service kiosks. In practice, selecting the right panel PC goes far beyond choosing the screen size alone – key factors include the front design (classic bezel or flat panel), ingress protection (e.g. IP65), fanless 24/7 operation, processor and operating system selection, available interfaces (Ethernet, RS-232/RS-485, USB), expansion options, and mounting method.
In this step-by-step guide, we walk through the key technical parameters of industrial panel PCs and explain how to select the right solution for a specific environment and application. Throughout the article, we also refer to selected models from our portfolio, including the CONPANEL PRO series: Conpanel Pro 10.1″ W2 J6412, Conpanel Pro 15.0″ W2 J6412, Conpanel Pro 15.6″ W2 J6412, Conpanel Pro 21.5″ W2 J6412, as well as the models: FIP-19RJ and FIP-15RB.

What is an industrial panel PC and where it is used
An industrial panel PC (Panel PC) is an all-in-one industrial device in which the display and the computing unit are integrated into a single enclosure. This approach eliminates the need for an external monitor, video cables and additional mounting brackets.
Thanks to their compact design, high environmental resistance and ability to operate continuously 24/7, panel PCs have become a standard component of modern automation systems, HMI applications and industrial process visualisation.
Panel PC vs a classic industrial BOX PC
The fundamental difference between a panel PC and a classic industrial BOX PC lies in the level of integration. In a panel PC, the display is an integral part of the device, which significantly simplifies the design and installation of operator workstations.
Panel PCs are designed for operation in demanding industrial environments. They typically feature a fanless design, a sealed front panel with an IP65 ingress protection rating, and enclosures made of aluminium or metal, ensuring efficient heat dissipation and high mechanical durability.
The role of panel PCs in HMI systems and industrial automation
In industrial automation systems, the panel PC serves as the central interface between the operator and the machine. It enables real-time monitoring of operating parameters, process visualisation, control of actuators and handling of alarms.
With support for operating systems such as Windows, Linux and Android, panel PCs can run both standard HMI/SCADA applications as well as manufacturer-specific software or web-based applications.
Combined with communication interfaces such as Ethernet, USB, RS-232 and RS-485, an industrial panel PC can be directly integrated with PLCs, frequency inverters, sensors, higher-level control systems and peripheral devices.
Panel PC screen sizes – ergonomics and application-based selection
Selecting the right screen size for an industrial panel PC is critical for operator ergonomics, HMI interface readability and overall system usability. A screen that is too small can hinder operation, while an oversized panel may generate unnecessary costs and mounting challenges.
In practice, the screen size should always be selected in relation to the installation location, the operator’s viewing distance, and the amount of information displayed simultaneously on the screen.
Small screens – local operator panels and machine control
Panel PCs with screen sizes of approximately 10–12 inches are most commonly used as local HMI panels mounted directly in machines, production lines or control cabinet doors.
They provide good interface readability at short viewing distances and help save space within the enclosure. A typical example of this solution is the Conpanel Pro 10.1″ W2 J6412 , which is well suited for simple HMI applications, test stations and control of individual machines.
Mid-size screens – versatile industrial HMI panels
Screen sizes in the 15–16 inch range represent the most versatile group of industrial panel PCs. They offer a balanced compromise between interface readability and mounting requirements.
These panels are commonly used on production lines, in SCADA systems, operator desks and quality control stations. In this category, proven models include the Conpanel Pro 15.0″ W2 J6412 and the Conpanel Pro 15.6″ W2 J6412 .
Large screens – process visualisation and supervisory stations
Panel PCs with screen sizes of 21 inches and above are designed for applications where operators need to analyse large amounts of data, charts or complex visualisations simultaneously.
Such panels are often mounted on walls, operator desks or at central monitoring points. A representative solution in this category is the Conpanel Pro 21.5″ W2 J6412 , which is well suited for advanced SCADA systems, BMS applications and industrial process monitoring centres.
Resolution, aspect ratio, brightness and contrast – what matters in practice
After selecting the screen size, the next key step is evaluating image parameters. These determine whether the HMI interface will be readable, alarms will be noticed quickly, and whether the panel PC will perform well in a specific installation location (shop floor, control cabinet, kiosk, or workstation near a window).
Resolution – interface readability and “space for data”
Resolution affects font sharpness, chart detail and the number of elements that can be comfortably displayed on a single screen. In SCADA systems and panels with advanced visualisation, insufficient resolution forces larger UI elements and more frequent screen switching.
In practice, the larger the screen and the more data displayed simultaneously (tables, trends, alarms), the more important higher resolution becomes. For simple HMI applications (a few buttons and basic status indicators), standard resolutions are often sufficient, but supervisory stations benefit from a more “comfortable working area”.
Aspect ratio (4:3, 16:9) – matching the application and HMI layout
The screen aspect ratio influences the layout of visualisation and whether an HMI application appears natural or requires non-standard scaling. In practice, the most common formats are 4:3 and widescreen formats such as 16:9.
The 4:3 format is often advantageous for classic industrial applications and legacy visualisations, while widescreen displays typically perform better for dashboards, trends and multi-window views. It is worth verifying the native aspect ratio of your HMI/SCADA software before selecting the target screen.
Brightness – visibility on the shop floor, near windows and in kiosks
Screen brightness is critical in environments with strong ambient lighting, daylight exposure or kiosk applications. Insufficient brightness makes the interface appear “washed out”, forcing operators to move closer or change their viewing angle.
If the panel is installed in high-light areas (near gates, on mobile stations, kiosks or close to windows), selecting the appropriate brightness level and, where applicable, the front design (e.g. flat panel) significantly improves usability.
Contrast – readability of symbols, alarms and UI elements
Contrast affects the ability to distinguish interface elements, icons, charts and messages, especially when the screen is viewed at an angle or under changing lighting conditions.
In industrial applications, rapid identification of critical states (alarms, faults, warnings) is essential. For this reason, image parameters should be evaluated not only “on paper”, but also in the context of the real operating environment.
Display types – non-touch, resistive touch and capacitive touch
Selecting the display type in an industrial panel PC directly affects operator ergonomics, input reliability and suitability for the environment (dust, moisture, gloves, contamination). In practice, you will encounter three main variants: non-touch, resistive touch and capacitive touch.
Non-touch display – when control is handled externally
Non-touch displays are chosen when the panel PC is used primarily as a status monitor or visualisation screen, while control is performed via other devices: pushbuttons on an operator desk, an industrial keyboard, joysticks/manipulators, a mouse, a scanner, or a higher-level control system.
This option can be optimal in applications where the panel is viewed from a longer distance and operator interaction is limited (e.g. production monitoring, KPI displays, Andon boards).
Resistive touch – precision and reliable operation in harsh environments
Resistive touch performs well in industrial applications where operators work with gloves, in environments with increased dust levels, contamination, or where predictable response to pressure is required.
This touch technology is often selected for heavy industry and locations where the panel may be operated with a tool or stylus. In practice, it is valued for stable operation under “less-than-ideal” conditions, although it typically does not support multi-touch functionality.
Capacitive touch – modern HMI, fast operation and multi-touch
Capacitive touch is the standard for modern operator panels, kiosks and applications where fast, intuitive interaction and gesture support (e.g. zooming, scrolling) are important. This variant works particularly well with HMI interfaces designed in a “tablet-like” style.
It is a popular choice for operator workstations in automation, visualisation systems in logistics, and self-service terminals. However, the touch selection should always consider the operator’s workflow (e.g. gloves) and the environment (moisture, dirt, cleaning agents).
In the next section, we will look at front design and bezels – including flat panel PC solutions, which improve aesthetics, make cleaning easier, and are often preferred in applications with increased hygiene requirements or frequent washdown.
Bezel and front design – flat panel PC vs classic enclosure
The front design of an industrial panel PC affects not only the device appearance, but above all the mounting method, ease of cleaning, and resistance to environmental conditions. In practice, there are two main approaches: a classic bezel and a flat panel PC design.
Classic bezel – a proven solution for embedded panel mounting
Panel PCs with a classic bezel are often selected for flush installation in control cabinet doors, operator desks and machine enclosures. The bezel helps secure the device firmly in place and provides a clear separation between the screen and the surrounding surface.
This approach works well in typical industrial applications where aesthetics are secondary and the key priorities are functionality, durability and compatibility with existing panels and enclosures.
Flat panel PC – a flush front and easy cleaning
A flat panel PC is characterised by a completely flush front surface, without protruding bezels or recesses. This design significantly simplifies cleaning and reduces the build-up of contaminants, dust and moisture.
For this reason, flat panel solutions are often selected for applications with increased hygiene requirements, such as the food industry, pharmaceutical environments, laboratories, as well as kiosks and terminals used by many people.
Bezel thickness and its impact on mounting
Bezel thickness and shape matter for embedded mounting and for integrating the panel PC with other components of an operator desk. Slim bezels and a flush front allow for a clean, modern look and a better fit within control panels.
When selecting the front design, consider both environmental requirements and whether the panel will be cleaned, washed down or used frequently by multiple operators.
Enclosures and materials – aluminium, metal and stainless steel
The material used for the enclosure of an industrial panel PC plays a key role in its durability, environmental resistance and suitability for continuous 24/7 operation. In practice, several typical construction approaches are used, each matched to specific operating conditions and industry requirements.
Aluminium enclosures – lightweight design and efficient heat dissipation
Aluminium is one of the most commonly used materials in industrial panel PCs. It offers very good mechanical properties combined with relatively low weight, while effectively dissipating heat from inside the device.
As a result, aluminium enclosures work particularly well with fanless designs, enabling stable operation in industrial environments without the need for active cooling.
Metal enclosures – enhanced mechanical durability
In applications exposed to vibration, impacts or intensive use, metal enclosures are used to provide increased mechanical strength and better protection for internal components.
Such designs are commonly found in heavy industry, on production lines and in machinery where the panel PC forms an integral part of the control system.
Stainless steel – aggressive environments and high hygiene requirements
Stainless steel is used in the most demanding applications, such as the food, pharmaceutical and chemical industries. This material offers high resistance to corrosion, cleaning agents and frequent washdown.
Panel PCs with stainless steel enclosures are selected for environments with strict hygiene standards, where the device must maintain full functionality despite intensive cleaning and harsh operating conditions.
When choosing the enclosure material, it is essential to consider the actual operating conditions: temperature, humidity, dust, potential exposure to chemicals and the cleaning procedures used.
IP protection ratings – resistance to water, dust and dirt
The IP (Ingress Protection) rating defines the level of enclosure protection against the ingress of solid objects (dust, dirt) and water. It is one of the most important parameters when selecting an industrial panel PC for a specific environment.
An incorrectly selected IP rating can shorten device service life, lead to unstable operation or cause failures due to moisture and contaminants.
IP65 – the standard for industrial panel PCs
IP65 is the most common protection rating for industrial panel PCs. It provides complete protection against dust and resistance to water jets from any direction.
This protection typically applies to the front of the device, which is sufficient for most industrial applications, such as production lines, operator panels and control cabinets.
Higher IP ratings – when they are required
In more demanding environments – for example in the food, pharmaceutical or chemical industries – higher IP ratings may be required to ensure resistance to intensive washdown or exposure to pressurised water.
In such cases, it is worth considering flat panel PC designs, stainless steel enclosures and additional sealing solutions, which reduce the risk of moisture entering the device.
Front vs rear protection – what to check
When assessing an IP rating, always verify which part of the device the declared protection applies to. Very often, the high IP rating covers only the front, while the rear of the panel PC is intended to be installed inside an enclosure or cabinet.
For this reason, selecting the IP rating should be aligned with the mounting method and the actual environmental conditions in which the industrial panel PC will operate.
Fanless design and 24/7 operation – industrial reliability
In industrial environments, device reliability is critical. For this reason, most modern industrial panel PCs are designed around a fanless architecture, suitable for continuous operation around the clock.
Fanless architecture – no moving parts
In fanless panel PCs, heat is dissipated passively through the enclosure, most commonly made of aluminium. The absence of fans means there are no mechanical components that can wear out or become blocked by dust and dirt.
This design significantly increases device resistance to contamination, moisture and vibration, which is particularly important on production floors and in industrial applications.
Continuous 24/7 operation – stability and long-term service life
Industrial panel PCs designed for 24 hours a day, 7 days a week must meet higher requirements than standard office computers. This applies both to component selection and to the overall device design.
Stable 24/7 operation is essential in HMI systems, production lines, SCADA installations and anywhere downtime leads to real operational losses.
Temperature tolerance and operating conditions
A fanless design, combined with appropriate enclosure material and passive cooling, allows industrial panel PCs to operate reliably across a wide temperature range.
This is particularly important in applications where the device is exposed to fluctuating conditions, increased ambient temperatures or the absence of air conditioning.
Motherboards, processors and system architecture – x86 and ARM
Selecting the hardware platform for an industrial panel PC directly impacts system performance, software compatibility and future expansion possibilities. A key role is played by the processor architecture and the motherboard used.
x86 architecture – compatibility and versatility
The x86 architecture is the most commonly selected solution for industrial panel PCs used in automation. Its main advantage is broad compatibility with operating systems and HMI/SCADA software.
Panel PCs based on x86 platforms can easily run popular Windows versions as well as Linux distributions, making them a safe choice for modernisation projects and expansion of existing installations.
Intel processors – J1900, J6412 and operating system implications
Industrial panel PCs use various generations of Intel processors, which differ in performance and supported operating systems. A common example is the Intel J1900 processor, which supports operating systems up to Windows 7.
Newer processors such as the Intel J6412 are designed to work with Windows 8, Windows 10 and Windows 11. In practice, this means that platforms based on J6412 do not support legacy systems such as Windows 7.
Processor selection should therefore take into account not only the required performance, but also the target operating system and the lifecycle of the application running on the industrial panel PC.
ARM architecture – energy efficiency and dedicated systems
An alternative to x86 platforms are solutions based on the ARM architecture, characterised by low power consumption and good performance in dedicated applications.
ARM-based panel PCs are commonly used in Linux- or Android-based systems, particularly for kiosk applications, IoT solutions and scenarios where full compatibility with traditional Windows software is not required.
Operating systems – Windows, Linux and Android
The operating system used in an industrial panel PC determines how the device integrates with existing infrastructure, its compatibility with HMI/SCADA software, and the possibilities for future system expansion. The OS choice should always be aligned with the application, the operating environment and the IT policy of the facility.
Windows – the automation standard and software compatibility
Windows remains the most widely used operating system in industrial automation and HMI applications. Its main advantage is broad compatibility with commercially available HMI/SCADA software, PLC programming tools and industrial applications.
Windows-based panel PCs are commonly deployed in production environments where existing software platforms, drivers and system integrations must be preserved during upgrades or system expansion.
Linux – stability, flexibility and dedicated systems
Linux is often selected for applications that require high stability, long-term support and a high degree of system customisation. It is particularly well suited for dedicated systems, embedded solutions and industrial applications with clearly defined functionality.
In industrial panel PCs, Linux is frequently used in custom-built HMI systems, web-based interfaces and applications where licensing costs and system transparency are important factors.
Android – kiosks, terminals and modern user interfaces
Android is used primarily in kiosk systems, user terminals and applications that require modern, touch-oriented user interfaces. It allows fast development of intuitive front-end applications and easy integration with web services.
Android-based panel PCs are most commonly found in self-service kiosks, information terminals, logistics applications and environments where a consumer-style user experience is a key requirement.
Configuration and expansion – RAM, SSD, graphics, WiFi/Bluetooth and LTE
The ability to configure and expand an industrial panel PC allows the system to be precisely matched to application requirements, both in terms of performance and available interfaces. Proper component selection directly impacts system stability, responsiveness and long-term reliability.
RAM – smooth operation of HMI and SCADA applications
The amount of RAM has a direct impact on application responsiveness and overall system stability. Insufficient memory can result in slow operation, delayed screen updates and longer response times in HMI or SCADA systems.
In practice, the required RAM capacity depends on the complexity of the visualisation, the number of simultaneously running applications and the operating system used. More demanding projects benefit from higher memory configurations.
SSD storage – reliability and vibration resistance
SSD drives are the standard storage solution in industrial panel PCs, offering high reliability, fast data access and resistance to vibration and shock. Compared to traditional hard drives, SSDs are better suited for continuous operation in harsh industrial environments.
Selecting appropriate SSD capacity should account for the operating system, application data, logging requirements and future system expansion.
Graphics and multimedia – when they matter
In many industrial applications, integrated graphics are sufficient for standard HMI and SCADA visualisation. However, more demanding use cases, such as multi-display setups, advanced dashboards or multimedia content, may require enhanced graphics performance.
In such scenarios, processor selection and graphics capabilities should be evaluated together to ensure smooth operation and consistent user experience.
Wireless connectivity – WiFi, Bluetooth and LTE
Wireless connectivity options such as WiFi, Bluetooth and LTE extend the flexibility of industrial panel PCs, enabling network access in locations where wired connections are impractical or unavailable.
These interfaces are particularly useful for mobile workstations, remote monitoring, temporary installations and applications requiring data transmission over cellular networks.
Communication interfaces and ports – USB, HDMI/VGA, Ethernet, RS-232/RS-485 and I/O
Communication interfaces determine how an industrial panel PC connects to external devices, control systems and industrial networks. Proper port selection is critical for seamless integration with PLCs, peripherals and higher-level systems.
USB ports – connecting peripheral devices
USB ports are used to connect a wide range of peripheral devices, including keyboards, mice, barcode scanners, printers, storage devices and service tools.
In industrial panel PCs, it is important to consider not only the number of USB ports, but also their accessibility and version (e.g. USB 2.0 vs USB 3.0), depending on data transfer requirements.
Video outputs – HDMI, VGA and DisplayPort
Video outputs allow the panel PC to be connected to external monitors or additional displays. Common interfaces include HDMI, VGA and, in some configurations, DisplayPort.
These outputs are particularly useful for multi-screen workstations, diagnostic displays or applications requiring extended visualisation.
Ethernet – network communication and system integration
Ethernet is the primary interface for network communication in industrial automation. It enables integration with PLCs, SCADA systems, MES platforms and corporate IT infrastructure.
Industrial panel PCs often feature one or more Ethernet ports, allowing separation of machine networks and higher-level systems or implementation of redundant network topologies.
RS-232 and RS-485 serial ports
Despite the widespread use of Ethernet, RS-232 and RS-485 serial interfaces remain common in industrial environments, particularly for connecting legacy devices, sensors and controllers.
The availability of serial ports in a panel PC simplifies direct integration with existing equipment without the need for additional converters.
Digital inputs and outputs (I/O)
In some applications, industrial panel PCs are equipped with digital I/O for simple control tasks, status signalling or direct interaction with external devices.
While not a replacement for PLCs, built-in I/O can be useful for auxiliary functions, diagnostics and compact control solutions.
Mounting methods and system integration
The mounting method of an industrial panel PC affects not only installation, but also ergonomics, service accessibility and long-term usability. Selecting the right mounting solution should take into account both the working environment and the operator’s workflow.
Embedded panel mounting
Embedded mounting is the most common installation method for industrial panel PCs. The device is mounted directly into a cut-out in a control cabinet door, machine panel or operator desk.
This approach ensures a clean, integrated appearance and protects the rear of the device, which is typically located inside the enclosure.
Wall mounting
Wall-mounted panel PCs are used where embedded installation is not possible or where the device needs to be easily accessible.
This solution is common in utility rooms, production halls and monitoring stations where space and visibility are key factors.
VESA mounting and stand mounting
Many industrial panel PCs support VESA mounting, allowing installation on arms, brackets or dedicated stands. This offers flexibility in positioning the device and adjusting it to the operator’s needs.
Mounting on a swing arm or boom
Swing-arm or boom mounting is used in workstations where the panel PC must be repositioned frequently. This solution improves ergonomics and is commonly found on production lines and operator stations.
Integration with accessories and external devices
Industrial panel PCs are often integrated with additional devices that extend system functionality and improve operational efficiency.
Barcode and QR scanners
Scanners are widely used in logistics, production and traceability systems for identification and data collection.
Label printers and industrial printers
Panel PCs are frequently connected to printers for label printing, documentation and reporting tasks.
Cash registers and payment terminals
In kiosk and self-service applications, industrial panel PCs can be integrated with payment terminals and fiscal devices.
Safety buttons and control components
Emergency stop buttons, signal lamps and control elements are often used alongside panel PCs to ensure safe operation and compliance with industrial safety standards.
Operating temperatures and environmental conditions
The environmental conditions in which an industrial panel PC operates have a direct impact on its stability, service life and overall reliability. For this reason, before selecting a device, you should precisely define the temperature range, humidity levels and dust exposure at the installation site.
Standard operating temperature ranges
Most industrial-grade panel PCs operate reliably across a wide temperature range suitable for production halls, control cabinets and operator workstations.
In typical industrial applications, ensuring proper cabinet ventilation or allowing free air circulation around the enclosure is usually sufficient to maintain stable system operation.
Extended temperature ranges – harsh environments
In more demanding conditions – such as outdoor installations, unheated facilities or high-temperature environments – it may be necessary to use panel PCs designed for extended temperature ranges.
In such cases, fanless architecture, the right enclosure material and the long-term stability of the selected components become particularly important.
Humidity, airborne dust and aggressive environments
Beyond temperature, you should also consider air humidity, the presence of dust, and potential exposure to chemicals. In such environments, the IP protection rating and the enclosure material are critical.
Correctly matching the industrial panel PC to environmental conditions helps prevent premature failures and ensures long-term, trouble-free operation.
Panel PC applications – use cases and technical requirements
Industrial panel PCs are used across a wide range of industries and applications. The final device configuration should always be selected based on the specific use case, environmental conditions and software requirements.
Industrial automation and production lines
In automation systems, panel PCs are most often used as operator HMI stations for machine control, production line supervision and real-time process monitoring.
In such applications, reliability, 24/7 operation, compatibility with PLCs and resistance to industrial environments are key selection criteria.
SCADA and BMS systems
Panel PCs are widely used in SCADA and BMS systems as visualisation terminals, control stations and monitoring points.
Larger screens, higher resolution and stable operating systems are particularly important in these applications.
Logistics, warehouses and traceability systems
In logistics and warehouse environments, panel PCs are commonly used for order picking, goods identification, labeling and traceability systems.
Integration with barcode scanners, label printers and ERP systems plays a crucial role in these scenarios.
Self-service kiosks and user terminals
Panel PCs are also used in self-service kiosks, information terminals and user interaction points.
In these applications, capacitive touch screens, modern operating systems and aesthetic front designs are often preferred.
Food and pharmaceutical industry
In the food and pharmaceutical sectors, panel PCs must meet strict hygiene and environmental requirements.
Flat panel designs, stainless steel enclosures and high IP protection ratings are commonly required to withstand washdown and cleaning procedures.
