MR-DOA4 Modbus RTU

The Modbus module with 4 digital outputs was developed for decentralized switching tasks. It is suitable for switching electrical components, such as motors, contactors, lamps, louvers, etc. With strong inductive loads, we recommend protecting the relay contacts additionally with an RC element. The outputs can be switched by means of standard registers via a Modbus master. Module address, bit rate and parity are set with two rotary switches on the front or by software.Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
