SC.EN is a two-channel 8.2Kohm interface relay, used for cleaning up resistive circuits (safety edge circuits) to provide clean NO/NC contacts for controls.
Power with 12 – 30 Vac/Vdc.
This unit can be used to incorporate up to 4 resistive circuits using specific dip switch settings, see images below.
