M-Bus to Modbus (RS485) Converter

NOTE: This product supports only BUS Network Topology on the MBus port.
Any other network topology is not supported and could cause errors on the network.

M-Bus to Modbus RTU (RS485) Converter is dedicated to convert M-Bus signal to Modbus (RS485) and to allow M-Bus devices to communicate on a Modbus network.

The M-Bus is a bus optimized for the reading of measurement instruments like energy counters, hot and cold water counters, gas, pressure, sensors and actuators, etc. Nowadays, more and more manufacturers implement the M-Bus interface in their counters, making it the ideal basis for remote reading applications.
