CPC1966BX8 is an AC Solid State Switch utilizing
dual power SCR outputs. This device features Rapid
Turn-On (non-zero-cross) control of the output SCRs,
which makes it ideal for precisely switching AC loads
independent of the load voltage phase.

The optically coupled input and output circuits
provide 3750Vrms of isolation and noise immunity
between the control and load circuits. As a result, the
CPC1966BX8 is well suited for industrial environments
where electromagnetic interference would disrupt the
operation of plant facility communication and control
systems.
