7 Communication via Modbus RTU

7.1

ControlPlex

controller

model

The EM12D-TMB has an internal

ELBus

interface enabling the communication with the electronic circuit

protector REX12D. Up to 16 channels of the REX12D electronic circuit protectors (single channeled, multi-
channeled or a mixed population) can be connected to the supply module.
