S642
1 Form A
Solid State Relay
DESCRIPTION
The S642 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.
