DESCRIPTION
The S842 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.

FEATURES
• Inverse parallel SCR output
• High transient immunity
• 700V blocking voltage
• 1.2A maximum continuous current
• Low input control current
• High input-to-output isolation
• Solid state reliability
• Zero-volt switching

APPLICATIONS
• Programmable controls
• Valve control
• Solenoids
• Remote switching
• Home appliances
• Metering equipment
• Heating elements
• Gas pump control circuitry
