The PM1205 is an AC Solid State Switch using 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 500VP. 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 3750Vrms 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.
