Would it be possible to take the 12V from the Computer Power Supply (CPS) and run it through a security light motion detector. I would like to use the motion sensor as a trigger.
Ok, you have a black, white and green wire on the cord that goes to the wall plug and a black, white and red wire on the sensor. Connect the black and white wires on the cord and sensor black to black and white to white. Just ignore the green wire, there's no ground on the relay or sensor. Connect a piece of white wire (just to keep the color coding consistent) to the white wires you connected. Connect that white wire to one of the coil terminals. Connect the red wire from the sensor to the other coil terminal. The sensor is now setup to activate the relay.So I connect the black and white wire to the Coil terminals on the relay...?
You can either solder the wires or use crimp on terminal like these: http://www.radioshack.com/product/index.jsp?productId=2103313Chewy-
How do I connect wires to the relay...solder? or is there a proper way?
