AC Relay Wildcard

Optically isolated, solid-state AC relays (AC SSR) control AC line operated devices

I/O interface board contains optically isolated AC Solid State Relays using Crydom AC solid state relay modules

The AC Solid State Relay Wildcard™ gives you independent control of up to four, 5 amp AC devices. Each AC relay is fully isolated from the others and switches at zero crossings of the AC line. These solid state opto-isolated relays (SSRS) are manufactured by Crydom and provide excellent reliability with a long life. Connect your AC Load to the easy to use Screw Terminal Connectors. Use the AC Solid State Relay WildCard to turn on and off larger relays, motors, pumps, heaters, refrigerators, valves, and fans.
