HD67146-485-A1 Modbus Master / MultiSlave converter

HD67146-485-A1 connects two Modbus Master devices to one or more slaves.

HD67146-485-A1 is an industrial Modbus Master / Modbus MultiSlave - Converter equipped with 3 x RS485 ports, designed for flexible integration of devices working in Modbus networks. The key advantage of this model is the possibility to connect two Modbus Master devices to one or more slave devices, which helps simplify communication architecture and makes it easier to build more advanced automation systems.

HD67146-485-A1 is well suited for applications where multiple supervisory devices must communicate with a Modbus network based on RS485 while maintaining stable and predictable data exchange. It is a practical solution for system integrators, machine builders, maintenance teams, and industrial projects where compact installation, efficient communication management, and easy expansion of the network are all important.

Thanks to its compact housing type A, 35 mm DIN rail mounting, and 3way 5mm terminal block connectors, the converter can be easily installed in typical industrial cabinets and control panels. The device supports data rates up to 115200 bps, while the wide power supply range of 8...19V AC and 8...35V DC gives more flexibility during both new installations and retrofit projects.

Another important benefit of HD67146-485-A1 is its wide operating temperature range from -40°C to +85°C, which makes it suitable for demanding industrial environments. In practice, this means the converter can be used in control cabinets, distributed automation systems, and industrial communication applications where Modbus performance must remain reliable over time.
