S942-X Datasheet, PDF (1/7 Pages) Solid State Optronic – Zero-Volt Cross Switching

S942-X
Zero Cross
800V / 1.2A
AC Solid State Relay
Description
The S942-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 S942-X provides high peak load
voltage (800V+) and high input-to-output isolation voltage
(up to 5kV_RMS).
The S942-X comes in a compact 16 pin DIP package,
making it ideal for high-density board applications.
