MR-DI4 | Contemporary Control Systems | Modbus RTU 4 Digital Inputs

The Modbus module with 4 digital inputs is designed for local switching operations. It is suitable to record potential-free switching states as for example electrical limit switches of ventilation valves or auxiliary contacts of power contactors. The inputs can be operated by potential-free switches or contacts and as voltage inputs. The inputs can be scanned via a Modbus-Master. Setting of the slave address, bit rate and parity is done with the two address switches (x1 / x10) on the front. Possible settings are addresses 00 to 99 and baud rates 1200, 2400, 4800, 9600, 19200, 38400, 57600 und 115200 Bd.
