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.

The following digital I/O modules are available:

• Digital input module DI 8X24VDC, 8XM8
• Digital input module DI 8X24VDC, 4XM12
• Digital input module DI 16X24VDC, 8XM12
• Digital output module DQ 8X24VDC/2A, 8XM12
• Digital input/output module DIQ 4+DQ 4X24VDC/0.5A, 8XM8
• Digital input/digital output module DIQ 4+DQ 4X24VDC/0.5A, 4XM12
• Digital input / output module IQ 16X24VDC/0.5A, 8XM12 with optional counter function
