Solid state relay, PS1201, LITTELFUSE

An AC solid state switch using optical coupling with dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. The switch is robust enough to provide a blocking voltage of up to 400 VP and a max surge current rating of 20 A. 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 3750 Vrms of isolation and noise immunity between the control and load circuits. As a result, it is well suited for industrial environments where electromagnetic interference would disrupt the operation of electromechanical relays.
