MR-DI10 | Contemporary Control Systems | Modbus RTU 10 Digital Inputs

The Modbus module with 10 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 as contact and voltage inputs (A1, 24VAC/DC, jumper J - A2) or with actuation to GND (A2, jumper J - A1), depending on the setting of the jumper J. 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 bit rates 1200, 2400, 4800, 9600, 19200, 38400, 57600 und 115200 Bd.
