For AC switching applications, this solid state relay is economical and reliable.


Using the digital outputs from a Phidgets device such as the OUT1100 - 4x Digital Output Phidget, you can control the relay to silently switch an AC circuit at 280V/20A or less.


This relay has a random turn-on, which means it doesn't wait for the AC signal to cross zero before switching on.

If your SSR is overheating, you should consider getting a heat sink for safety. See the related products for compatible heatsinks. This SSR comes with a heat transfer pad that can be placed between the metal base of the SSR and the surface it's mounted to in order to help encourage heat flow. It also comes with a varistor that can be used to protect your SSR against voltage spikes in some applications.

Comes Packaged with

Accessories

This SSR comes with a heat transfer pad and a protective cover. Use the heat transfer pad whenever mounting the SSR on a heat sink or metal surface. We recommend that you use the plastic cover if there is any risk of a person or conductive material accidentally touching the load side contacts. The other AC we relays we've sold in the past have come with an external varistor. This relay has additional protective circuitry inside, so an external varistor is not needed.
