Digital inputs record 24 V DC signals in the plant and forward them to the controller. Switches and 2, 3 or 4-wire proximity switches can be connected.

Digital outputs switch 24 V DC voltages in the plant, thus transferring internal signals from the controller to the plant. Solenoid valves, DC contactors, and indicator lights can be connected.

The 30 mm and 45 mm wide I/O devices are especially suitable for use in extremely confined spaces. All I/O devices have configurable parameters and diagnostic functions and can thus be freely adapted to the respective process requirements.
