Digital input modules record 24 V DC or 230 V AC signals in the plant and forward them to the PLC. Switches and 2, 3 or 4-wire proximity switches can be connected.

High Feature modules feature configurable parameters and diagnostic functions and can thus be freely adapted to the respective process requirements.

Low cost input modules do not have settable parameters or diagnostic functions and are therefore very easy to integrate into the engineering. They are recommended for use in locations where only very few input channels are necessary or under conditions of use in which a high number of channels must be implemented in a very limited space.

Both module types can be used side by side in one station as required. Standardized features and shared system accessories guarantee easy handling.
