Description
The S842-X is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay. The circuit is composed of one input IR LED with a series limiting resistor which activates an optically coupled IC on the output that controls the firing angle of two back-to-back SCRs. This circuit assures no false triggering under most adverse conditions, and a tight zero-volt switching window not exceeding 5V. The S842-X provides high peak load voltage (700V+) and high input-to-output isolation voltage (up to 5kVRMS).
