Industrial RS485 to Profibus converters, control and communication

Industrial RS485 to Profibus Converters

In this section of our shop, you will find a wide selection of RS485 to Profibus converters designed for industrial applications. These devices enable communication between RS-485-based equipment and Profibus DP networks, facilitating seamless integration of serial devices into modern automation infrastructures. Profibus is widely used in industries such as manufacturing, water treatment, energy management, and building automation due to its reliability, speed, and robustness.

The converters allow a wide range of RS-485 serial devices—including weighing systems, barcode scanners, industrial sensors, cash registers, and energy meters—to operate within a Profibus ecosystem. This integration is essential in control systems where communication with Siemens S7 PLCs, decentralised I/O modules, and various SCADA interfaces is required. Our devices are suitable for retrofitting existing installations or building new automation solutions based on Profibus DP-V0 protocol.

Learn More About Our RS-485 to Profibus Converters

Every RS-485 to Profibus converter in our range is built with industrial-grade specifications. They support a wide input voltage range of 12–35VDC or 24VAC, offer DIN rail mounting (TH35), and are designed for use in harsh environments. Their rugged construction ensures stable performance in control cabinets, near heavy machinery, and in outdoor installations exposed to extreme temperatures from -40°C to +85°C. This makes them ideal for demanding industrial automation and process control environments.

Our converters are equipped with screw terminals for RS-485 connections and a DB9 connector for Profibus, ensuring compatibility and ease of installation. Each device provides 3000V galvanic isolation to protect your equipment from electrical noise, surges, and ground loop issues. The Profibus interface supports automatic baud rate detection up to 12 Mbps, while the RS-485 side handles speeds up to 115.2 kbps, covering a wide range of industrial communication needs.

Simple Configuration and Fast Commissioning

Each converter comes bundled with free configuration software that simplifies setup. The tool requires no licenses and allows users to define Modbus addresses, communication parameters, and generate a compatible GSD file. This file can be easily imported into the Profibus master configuration software, enabling quick commissioning and compatibility with leading PLC brands such as Siemens, Schneider, and B&R.

Whether you're developing a BMS system, integrating HVAC control units, or upgrading legacy infrastructure, our RS485 to Profibus gateways offer unmatched reliability and ease of deployment. Their EMI resistance, robust casing, and flexible protocol support ensure long-term stability in mission-critical applications.
