HD67B71-232-A1 PROFINET Master to Modbus RS232 slave converter for DIN rail

Industrial PROFINET Master to Modbus slave converter, port RS-232, housing type A (slim), DIN rail mount. 

The HD67B71-232-A1 is a compact and efficient industrial gateway designed to enable seamless communication between PROFINET Master networks and Modbus RS232 slave devices. Ideal for integration with PLCs, HMIs, SCADA systems and other automation controllers, this converter ensures reliable and high-performance data exchange across protocols.

With support for up to 4096 bytes in both read and write directions, the HD67B71 can handle large amounts of process data, making it suitable for demanding industrial applications. It is particularly useful in retrofit projects, where RS232-based Modbus slave equipment needs to be upgraded to communicate with modern PROFINET-based systems.

The device features a robust slim-type A housing with DIN rail mounting, allowing easy installation even in narrow control cabinets. It operates reliably in extreme temperatures from -40°C to +85°C, and its wide power input range from 8…24V AC or 12…35V DC ensures flexibility in different industrial environments. Configuration is performed via the SW67B71 software, available free of charge.
