The 3953_0 AC Solid State Relay can be used to switch loads of up to 120A at 20VAC using the digital output from a Phidget I/O board.


Package includes:



  • A Heat Transfer Pad

  • TMOV20RP200E varistor

If your SSR is overheating, you should consider getting a heat sink for safety. Heat sinks 3955 and 3956 are compatible with this device. 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.

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.
