S742-X Datasheet | Solid State Optronic

.. 1 Form A Solid State Relay DESCRIPTION The S742-X is a bi-directional, single-pole, single-throw, normally open multipurpose relay. The circuit is posed 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. A 300-ohm input resistor in series with the LED is also provided in this circuit.
