HD67B71-485-A1 industrial PROFINET Master to Modbus RS485 slave DIN converter

Industrial PROFINET Master to Modbus slave converter, port RS485, housing type A (slim), DIN rail mount. 

The HD67B71-485-A1 is a compact and robust converter designed for seamless data exchange between a PROFINET Master network and a Modbus RTU Slave device over the RS485 interface. It is intended for industrial applications requiring reliable, two-way communication across protocols and topologies.

This converter supports up to 4096 bytes in both read and write operations, ensuring high-throughput communication. Its DIN rail mountable slim housing (Type A) makes it easy to install in compact control cabinets. The converter is ideal for integrating legacy Modbus systems with modern PROFINET networks, such as PLCs or SCADA systems.

Thanks to its wide power supply range (8–24V AC / 12–35V DC) and broad operating temperature range (-40°C to +85°C), the HD67B71-485-A1 is suitable for use in harsh industrial environments. Configuration is handled via the free SW67B71 software, which allows easy mapping of Modbus registers to PROFINET objects without requiring deep protocol knowledge.
