The 3954_0 AC Solid State Relay can be used to switch loads of up to 50A at 120VAC using the digital output from a Phidget I/O board.
Package includes:
- A Protective Relay Cover
- A Heat Transfer Pad
- An MOV (Metal Oxide Varistor)
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.
