M-Bus to Modbus converter Mbus-RS485

M-Bus to Modbus RTU (RS485) Converter changes M-Bus signal to Modbus (RS485) and allows M-Bus devices to communicate on a Modbus network.

The M-Bus is a bus designed to read measuring instruments such as energy meters, hot and cold water meters, gas, pressure, sensors and actuators, etc. Nowadays, more and more manufacturers are implementing the M-Bus interface in their meters, making it an optimal device for remote reading and intelligent measurement applications
