S942
Zero Cross
800V / 1.2A
AC Solid State Relay
Description
The S942 is a bi-directional, single-pole, single-throw,
normally open multipurpose solid-state relay. The circuit is
composed of one input IR LED 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 S942
provides high peak load voltage (800V+) and high input-to-
output isolation voltage (up to 5kV_RMS).
The S942 comes in a compact 16 pin DIP package, making
it ideal for high-density board applications.
