PM1204
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 PM1204switches 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.

Electrical Characteristics
Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the opera-tional sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and effect its reliability.
