For high current loads, this solid state relay is the way to go. Using the digital outputs from a Phidgets device such as the OUT1100 - 4x Digital Output Phidget, you can control the relay to silently switch a DC circuit at 120V/75A 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 Connection & Compatibility 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 diode that can be used to protect your SSR against back EMF.
This relay comes packaged with a heat transfer pad and a 10A02-T diode. Use the heat transfer pad whenever mounting the SSR on a heat sink or metal surface. Use the diode in parallel with your load in order to protect your SSR. For more information, see the Solid State Relay Primer.
This relay can be controlled using a Phidgets relay output board. See the Connection & Compatibility tab for details.
This SSR can be controlled either by using a high-power digital output (such as those on the OUT1100 - 4x Digital Output Phidget) or by using an open-collector digital output and a 5V source, which can be done with the 1012 - PhidgetInterfaceKit 0/16/16.

If you're switching high current devices or circuits, we recommend that you use a heatsink. In some applications, you may be able to mount the relay to a metal surface which can act as a heatsink by itself. This relay comes with a heat transfer pad that you can sandwich between the relay and the heatsink or mounting surface. When screwed on tight, it will eliminate any air gaps and ensure that the heat conducts from the relay to the heatsink. In cases where the heatsink cannot dissipate heat fast enough, you should add a fan to one end of the heatsink so that air is constantly moving through the fins.
