The CPC1961 is a dual single-pole AC solid state
relay that uses optical coupling with dual monolithic
SCR outputs to produce an alternative to optocoupler
and Triac circuits. The CPC1961 switches are robust
enough to provide up to a 600VP blocking voltage. 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 CPC1961 is well suited for industrial environments
where electromagnetic interference would disrupt the
operation of electromechanical relays. The CPC1961 is
offered in a space saving 8-pin DIP package with two
independent switches.
