Ac relay switch wiring. This circuit has one relay a refrigerant pressure switch and a micro switch. Checking an a c clutch relay is a process of eliminating possible connection failures. The square relay pinout shows how the relay socket is configured for wiring. The factory wiring in modern cars is light gauge and is not designed for additional loads.

Wire ac relay. The tb6560 has an onboard relay switch however it is a dc relay and only capable of handling voltages from 12v to 36v dc. The air conditioning clutch relay transfers power like a switch from the interior a c controls of an automobile to the a c compressor engaging the compressor clutch. 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.

Npn relay switch circuit. Relay switch instructions when using the halo led on a newer hvac unit utilizing a variable speed fan or ramping motor with constant on 24 volt control it is recommended the enclosed relay or similar 24vac coil spdt be used in order to turn off the power to the halo led when the hvac unit is turned on and off. Every circuit added to a modern car should be run through an automotive relay. Relay is an electro mechanically operated switch however other operating principles are also used in relays such as solid state relays.

A relay can be used to power a new circuit with very little added current draw on the original wiring. Wiring the relay to the tb6560. A relay is generally used when it is required to control a circuit by a separate low power signal or when several circuits must be controlled by one signal. Using a relay can also shorten the distance.

These instructions will explain how to wire the relay to the tb6560 driver board power supply and auxiliary power panel. This pinout image is only a 2 pole diagram for room on the page purposes but you can get the picture here with this one since a 3 pole will just have 1 more set of contacts. When the base voltage of the transistor is zero or negative the transistor is cut off and acts as an open switch. The micro switch is a w o t or wide open throttle switch used to disengage the compressor clutch during wide open.
