The 3952 DC Solid State Relay can be used to switch loads of up to 100A at 30VDC using the digital output from a OUT1100 - 4x Digital Output Phidget. The Relay comes with an optional protective cover to protect people from touching the exposed high power wires, and a diode to protect your SSR from harmful transients. All wires connect to this relay by screw terminals. If you are switching a high power load or find the relay is getting hot, please consider a heat sink. Heat sinks 3955 and 3956 are designed for use with this relay.
This solid state relay can be controlled with Phidget digital outputs. For more details, see the Connection & Compatibility tab.
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.
