The MOC303XM and MOC304XM devices consist of a AlGaAs infrared emitting diode optically coupled to a monolithic silicon detector performing the function of a zero voltage crossing bilateral triac driver.

They are designed for use with a triac in the interface of logic systems to equipment powered from 115 VAC lines such as teletypewriters, CTRs, solid-state relays, industrial controls, printers, motors, solenoids and consumer appliances, etc.

• Simplifies logic control of 115 VAC power

• Solenoid/Valve controls
• Lighting controls
• Static power switches
• AC motor drives
• Temperature controls
• E.M. contractor
• AC motor starters
• Solid state relays
