Dual 1 Form B Solid State Relay
DESCRIPTION
The AD4C312 is a bi-directional, double-pole, single-throw, normally closed multipurpose solid-state relay. It is designed to replace electromechanical relays in general purpose switching applications. The relay consists of two integrated circuits, each driving a pair of rugged source-to-source depletion type DMOS transistors. Each integrated circuit is optically coupled to a light emitting diode. The output MOS transistors are protected with free-wheeling diodes that can handle up to 1. 5A of inrush current, making the relay ideal for switching lamps and highly inductive loads.
