DC Solid State Relay - 30V 100A

£50.80 £42.33

This SSR switches up to 30VDC/100amp and connects to a PhidgetInterfaceKit 0/16/16 or OUT1100.


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.
