Crydom's CW24 line of solid state relays offer

an SCR AC switch output featuring low off-

state leakage (1mA, snubberless), zero and

random voltage switching and a broadened

operating range (24-280Vac). This wide

range permits optimum perfomance at both

120Vac and 240Vac line voltages.

Manufactured in Crydom's ISO 9001

Certified facility for optimum product

performance and reliability.
