The PS1201 is an AC Solid State Switch using optical
coupling with dual power SCR outputs to produce an
alternative to optocoupler and Triac circuits. The
PS1201 switches are robust enough to provide a
blocking voltage of up to 400VP and max surge
current rating of 20A. 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 PS1201
is well suited for industrial environments where
electromagnetic interference would disrupt the
operation of electromechanical relays.
