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 wide I/O modules are especially suitable for use in extremely confined spaces, have settable parameters and diagnostic functions and can thus be adapted flexibly to the respective process requirements.
