SP646-X
1 Form A
Solid State Relay
DESCRIPTION
The SP646-X 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. 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.
