SIMATIC S7-1500 – SM 522 Digital Output Module – Siemens Digital Modules

Digital output modules switch 24 V DC or 230 V AC voltages in the plant and thus transfer internal signals from the PLC to the plant. Solenoid valves, DC contactors, and indicator lights can be connected.

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

Low-cost 25 mm wide output modules do not have settable parameters or diagnostic functions and can therefore be integrated very easily 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.
