Description

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.
