Solid state relay, PM1205S, LITTELFUSE An AC solid state switch uses 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 500 VP. In addition, tightly controlled zero-cross circuitry ensures the 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 could disrupt the operation of electromechanical relays. Features Zero-crossing detection DC control, AC output Optically isolated Low EMI and RFI generation High noise immunity VDE compatible Flammability rating UL 94 V-0 Applications Programmable control Process control Power control panels Remote switching Gas pump electronics Contactors Large relays Solenoids Motors Heaters
