HD67B71-422-A1 PROFINET Master to Modbus RS422 slave converter, DIN rail mount

Industrial PROFINET Master to Modbus slave converter, port RS422, housing type A (slim), DIN rail mount. 

The HD67B71-422-A1 converter enables seamless communication between a PROFINET Master network and Modbus RTU devices using the RS422 interface. It is designed to integrate industrial controllers such as PLCs, HMIs or SCADA systems with Modbus slave nodes. This converter is an essential component for multi-protocol environments requiring reliable data exchange and protocol conversion.

The device supports up to 4096 bytes in both reading and writing directions, ensuring high data throughput for demanding industrial applications. With bidirectional data flow, it provides full flexibility for mapping Modbus registers to PROFINET objects and vice versa. The compact DIN rail-mountable housing is ideal for space-constrained installations in electrical cabinets and automation enclosures.

Thanks to its wide power supply range (8–24V AC / 12–35V DC) and operating temperature from -40°C to +85°C, HD67B71-422-A1 is suitable for harsh industrial environments. The configuration process is user-friendly and carried out through the dedicated software SW67B71, available as a free download from the manufacturer’s website.
