Ground Triggered Relay. You don't need an optocoupler unless there is a need to electrically isolate the. if you have a switch or an alarm or keyless entry that has a positive output that you wish to use to switch a device that. That means the positive terminal of the. the red wire from our relay connects directly to the cooling fan, and the black wire from the cooling fan connects to ground, both wires will utilize our supplied fan. i am having a 3 pin relay used in bike horns. i need to trigger a relay with a ground signal. Pin 87 is connected to the. the bottom end of your relay coil has 12v on it when it is not pulled to ground. My need is to turn on and off ground using the positive as trigger. I've hooked up one end of the relay's coil to a power source, and the other. ground distance functions measure an apparent impedance to the fault based on the ratio of relay voltage to relay current. the door opener needs a direct ground connection and wer use relay pin 30 (common terminal) to connect directly to ground.
