Ac Relay Switch Wiring
Relays have many purposes and are used in a variety of ways such as electronic circuit boards machines appliances automobiles and the list can go on.
Ac relay switch wiring. This is done by energizing a coil which is internal to the relay and by energizing the coil the relay changes state just like a wall switch would. This setup turns the fan on as soon as the a c switch is turned on. Make sure the power switch on the power chassis is in the off position. It s now time to connect everything up.
Run the wire connected to pin 1 on tb6560 to terminal 2 on the power supply and tighten the screw. Without this relay the ac compressor will not have power and the ac system will not function. The actual wiring may contain other components such as transistors and ic computer chips but the control itself is the same. A relay is switched by electrical power and not a human.
Ac relay wiring diagram 2007 dodge caliber 20 without a c engine diagram wiring diagram name ac relay wiring diagram wiring diagram is a simplified pleasing pictorial representation of an electrical circuit. With the engine running turn the a c control or switch to on at the dashboard. The low voltage signal passing through the coil creates an electromagnetic field which closes the relay s contact points. I will show how to make an automatic fan control switch which will switch on a 12v dc fan in case when the power company 220v will be absent.
Check the three wires again. Almost every single electrical system on a car is powered through some kind of switch or electrical relay and the ac system and compressor are no exception. Now run the wire connected to pin 3 on the tb6560 to terminal 3 on the ac relay and tighten screw. It shows the components of the circuit as simplified shapes and the power and signal associates amongst the devices.
Therefore when you energize a relay you are switching circuits off and on. Unplug any relay terminal wiring with the interior car a c controls in the off position. In all cases these extra components are used to control the relay. Check all three wires with the test light.
If you have a c and would like to have the option of turning on the electric fan when the a c is turned on you can use an additional 500479 relay kit wired as shown. The ac compressor relay is responsible for supplying power to the ac compressor and clutch.
