3950_0 DC Solid State Relay - 30V 50A

£29.38

The 3950 DC Solid State Relay can be used to switch loads of up to 50A at 30VDC using the digital output from a 1012 - PhidgetInterfaceKit 0/16/16.

Package includes:

  • A Protective Relay Cover
  • A Heat Transfer Pad
  • A Diode

Details

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.

Have a look at the relay's characteristic curve in the Data Sheet to decide if you need a heat sink. Without a heat sink, the maximum current that can be handled by this relay is 18A up to an ambient temperature of 40°C.

In order to be able to switch currents of up to 80A, you have to use the 3955 - Heat Sink 

This relay connects to the 1012 - PhidgetInterfaceKit 0/16/16.
Just connect the positive control terminal of the SSR to the +5V terminal on the 1012, and connect the negative terminal to an open collector digital output on the 1012.
