5 Pin Relay Wiring Ground Trigger

Correct me if i m wrong but i m assuming that if i send 5v 2a to the trigger pin it will fry it.

5 pin relay wiring ground trigger.

Some older door lock systems found on domestic cars omit the relays and use a thicker gauge wiring instead. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating. Since the relay has 5v trigger voltage we have used a 5v dc supply to one end of the coil and the other end to ground through a switch. Iso mini relays with two circuits one of which is closed when the relay is at rest and the other which is closed when the relay is energised have 5 pins on the body and are referred to as changeover relays.

The power circuit instead of the ground circuit is used to energize the relay s coil. I was thinking of doing this last night but thought i d need a bigger ground wire than was going to the old horn but the ground for the nautilus horn is going to be a separate wire that i ground myself. Otherwise there is no way to do it with a 3 pin relay as shown. That s why i m trying to fiddle with the wires that leave the relay not the relay itself.

So how do i drop the multage and or amperage to safely operate this relay. If you have only a positive signal for horn then you can add a small 12v relay to operate the horn relay or add a transistor and a resistor and a flyback diode. I have attached the electrical wiring diagram from the turn indicator i believe what you will discover is that the turn signal and hazard the 8 pin flasher relay toyota is using here is kinda alien to me. It should have 4 prongs two of which trigger the relay 85 86 open close the switch and the.

No information came with the relay for the voltage. I have the relay in the picture above and have it powered with 5 volts. Normally open relays are the more common type. I don t think so.

These have two contacts connected to a common terminal. So you should connect pin 86 to 12 pin 87 to the horn wire and to make the horn beep you ground pin 85. Think of the relay as an electrically actuated switch.
