MR-F-DOA4
The MR-F-DOA4 is a Modbus RTU module that is ideal for decentralised switching tasks in building and automation technology. It has four changeover relays that can be used to control actuators such as signal lights, acoustic signal transmitters or contactors. The relays are controlled via standard registers using a Modbus master (e.g. a COMTRAXX device). Addressing and setting the bit rate and parity can be done using front switches.
