The PM1204 is an AC Solid State Switch using optical coupling with dual power SCR outputs to provide an alternative to optocoupler and Triac circuits. The PM1204 switches are robust enough to provide a blocking voltage of up to 400V. In addition, tightly controlled zero cross circuitry ensures switching of AC loads without the generation of transients. The input and output circuits are optically coupled to provide 3750V of isolation and noise immunity between control and load circuits. As a result the PM1204 is well suited for industrial environments where electromagnetic interference could disrupt the operation of electromechanical relays.
