MB-CR-64 M-Bus to Modbus Converter suitable for up to 64 meters

MB-CR-64 is microcontroller-based bidirectional M-BUS Master converting M-Bus signal to Modbus RS-485 RTU and or Modbus TCP.

It can supply power to maximum of 64 m-bus slave devices. MB-CR-64 is used as a bridge in building and industrial networks where it is needed to read m-bus devices (tax meters and/or sensors) in Modbus based SCADA systems. It has output short circuit protection on m-bus side.

It is mounted on standard M36 DIN rail.
