S742

1 Form A

Solid State Relay

The S742 is a bi-directional, single-pole, single-throw, normally open multipurpose relay. The circuit is composed of one LED on the input

side which activates an optically coupled IC on the output - controlling the firing angle of two back-to-back SCRs. This circuit assures no

false triggering under most adverse conditions, and a tight zero-volt window not exceeding 5V.
