The SP646 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.

le-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. FEATURES APPLICATIONS • • • • • • • Zero-Volt Cross Switching High transient immunity 400V blocking voltage 1.
