Modbus RTU Module MR-Multi-I/O, 11 optocouplers, 1xS0 … 24 V AC/DC, +/- 10%

The MR-Multi-I/O Modbus module is a compact and quick-to-install solution for connecting digital and analog signals from the actuator and sensor level directly to a control unit in building automation via the Modbus RTU protocol. A total of 29 I/Os, some of which are configurable, are available for various tasks. In the case of high inductive loads, the relay contacts must also be protected with an RC circuit. With a Modbus master, the inputs and outputs can be switched and queried via standard registers. The module address, baud rate, and parity are set via two rotary switches on the front panel or via software. Suitable for decentralized mounting on a TH35 mounting rail according to IEC 60715 in electrical distribution panels.
