Description
The PM1204 is a AC Solid State Switch using optical cou-
pling with dual power SCR outputs to produce an alter-
native to optocoupler and Triac circuits. The PM1204
switches are robust enough to provide a blocking voltage
of up to 400V. In addition, tightly controlled zero cross cir-
cuitry ensures switching of AC loads without the genera-
tion 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 PM1204 is well suited for industrial environments
where electromagnetic interference could disrupt the
operation of electromechanical relays.
