Industrial RS-232 to PROFIBUS converters

In this part of our store, you will find high-performance converters from the RS-232 to PROFIBUS standard. The PROFIBUS communication protocol is widely used in industrial automation for seamless communication between field devices, controllers, and decentralized I/O modules. These converters are designed to bridge devices with RS-232 serial communication ports, such as sensors, data loggers, industrial PCs, barcode scanners, or HMI panels, with PROFIBUS DP networks. Thanks to this integration, data can be efficiently exchanged between legacy RS-232 systems and modern PROFIBUS-based automation environments.

Get to know our RS-232 to PROFIBUS converters better

Each RS-232 to PROFIBUS converter in our portfolio offers reliable performance in challenging industrial conditions. With easy DIN rail mounting (TH35), wide input voltage support (12–35VDC or 24VAC), and operational temperature ranges from -40°C to +85°C, they are perfectly suited for both indoor and outdoor installations, including control cabinets exposed to high heat and external boxes subjected to frost or humidity. Their robust metal enclosures provide resistance against mechanical stress, shock, and vibration.

The converters are equipped with isolated RS-232 serial ports (DB9 or terminal block) and PROFIBUS DP (DB9) ports supporting transmission speeds up to 12 Mbps with 3000V galvanic isolation for enhanced communication safety. Our converters comply with PROFIBUS DP V0 protocol, making them fully compatible with Siemens S7 series PLCs, SCADA systems, and other industrial control solutions.

Configuration is quick and intuitive thanks to the free configuration software provided with every unit. No additional licenses are required. Once the RS-232 port parameters are defined, the tool automatically generates a GSD file compatible with PROFIBUS masters, simplifying system commissioning. Users can also map Modbus RTU registers from RS-232 devices to specific PROFIBUS addresses for seamless data exchange between devices.

Applications for RS-232 to PROFIBUS converters span across many sectors including factory automation, power plants, water treatment facilities, oil & gas installations, and infrastructure monitoring systems. These converters are ideal for modernizing existing equipment with serial communication interfaces, allowing them to be reused in new PROFIBUS-based architectures without replacing the entire hardware stack.
