AC Solid State Relay – 280V 25A

Product Description

For AC switching applications, this solid state relay is economical and reliable. Using the digital outputs from a Phidgets device, you can control the relay to silently switch a AC circuit at 280V/25A or less. There’s an indicator LED on the control side of the circuit so you can tell the state of the relay at a glance.

If your SSR is overheating, you should consider getting a heat sink for safety. See the “Compatible Products” tab for a list of 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

This SSR comes with a heat transfer pad and a TMOV20RP200E varistor. Use the heat transfer pad whenever mounting the SSR on a heat sink or metal surface. If you’re switching a load at 120V or less, you can put the varistor across the load terminals in parallel with the rest of the load circuit in order to protect your relay from voltage spikes. If you’re switching a load higher than 120V, do not use the varistor. For more information, see the Solid State Relay Primer.

Connection

This relay can be controlled using a Phidgets relay output board. See the “Compatible Products” tab for details.
