Inputs can be received from push buttons, limit and proximity switches, termperature and pressure switches, as well as other VDC sources. Eight independent threshold switches sense inputs from an external power source.

Each input is electrically isolated by an optical coupler. An LED indicator connected to the circuit's field side displays the true ON/OFF state of the input. Both the IEEE and ANSI standards for surge withstand capability (SWC) tests are fully satisfied. This enables the module and controller to withstand severe voltage transients prevalent in industrial environments.
