the pm1205 is an ac solid state switch that uses optical coupling with dual power scr outputs to produce an alternative to optocoupler and triac circuits. the pm1205 switches are robust enough to provide a blocking voltage of up to 500v. in addition, tightly controlled zero crossing 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 pm1205 is well suited for industrial environments where electromagnetic interference could disrupt the operation of electromechanical relays.
The CLARE PM1205 is an AC Solid State Switch designed to provide robust switching of AC loads up to 500V. It utilizes optical coupling with dual power SCR outputs to ensure high noise immunity and isolation between the control circuit and the load, making it suitable for environments where electromagnetic interference could disrupt electromechanical relays.
