ControlPlex® DINrail EM12D-TMB

The EM12D-TMB intelligent supply module allows the REX system to be connected to the bus system Modbus RTU. The system can quickly be integrated into the infrastructure of building automation and plant engineering and construction. Permanent recording of status and measuring data creates a hitherto unknown transparency in the area of DC 24 V power supplies. Well-proven overcurrent protection is combined with the communication capabilities of field bus systems.

The intelligent REX system is able to log measuring values such as the present current value of the load and status information data of up to 16 channels and to transmit them to the superordinate control system. In addition the parameterisation of the electronic circuit protectors is ensured. The current rating of the adjustable REX12-TE can be adjusted via visualisation. This allows to respond quickly to changing system configurations and adjustable ratings also help reduce inventory.


  • Higher system availability through connection to Modbus RTU
  • Maximum transparency through permanent recording of status and measuring data
  • Parameterisable circuit protectors reduce inventory
  • Space savings in the control cabinet through only 12.5 mm wide modules
