Relay Board for 2 x 1A Miniature Relays
 
Quite often the hobbyist needs to use a relay. For example the output of a PIR has output pads for the alarm signal which must be connected to a remote switching device. To fill needs like these we have two kits which are just a relay, PCB and terminal blocks for the input/output signals. There are many relay pin-outs & drive voltages to select from. We have standardized on two 12V relays from Goodsky Relay Board for 2 x 1A Miniature Relays(CPS45)
