Modbus RTU Module MR-DIO4/2, 4 digital inputs, 2 relay outputs, with manual control interface, 250 V, 16 A

The Modbus module, featuring 4 digital inputs and 2 relay outputs with a manual control level, was developed for decentralized switching tasks. It is suitable, for example, for connecting light switches and window contacts in a room to control two light strips or for use as a blind control system. It can also control 2 motor-driven fire dampers. In this case, the relay contacts must be protected by appropriate load-dependent measures. The inputs can be operated as contact or voltage inputs. Via a Modbus master, the inputs and outputs can be switched and queried using standard registers. The module address, baud rate, and parity are set via two switches on the front panel or via software. Suitable for decentralized installation in a series sub-distribution panel. Connection via screw terminals. Also available with spring terminals.
