Types of automotive relays. The type b layout is arguably easier to work with as the connected terminals are in line making the wiring easier to visualise. However the real benefit behind a relay is more than just automation. The purpose of an automotive relay is to automate this power to switch electrical circuits on and off at particular times. Evolute solutions private limited. Types of automotive relays change over relays. If you need to.
You will notice that on the type b layout pins 86 and 30 are swapped over compared with the type a layout. 12v dc relay switches are the best solution for full voltage. A make and break relay has four pin terminals and a single high current circuit. Look for relay diagrams or a relay schematic that is printed on the side of the relay to determine its function. Trustseal verified call 91 8048600726. The most common relays used to control electrical accessory devices in the automotive industry are iso mini and micro relays.
Wiper alarm system power antenna power window towing bar air conditioning system lamp control. These automotive relays have the standard five pins and can. 20 30 and 40 amp relays are common in automotive use. Relays are switches controlled by electrical power like another switch computer or control module. Automotive relay types in order to cope with a variety of applications installed in vehicles we have lined up of several external shapes and specifications suitable for each application. Types of automotive relays.
Below are some examples of basic 12 volt dc car relays. They also provide the ability to switch multiple circuits including different voltage types within the same relay at the same time. Single pole single throw v. A potted relay. This is the most common type of relay. 125 madhuram industrial estate behind visava hotel sativali road vasai east palghar 401208 dist.
4 and 5 pin designs spst spdt are used in both styles of automotive relays. Make and break relays. Normally open or normally closed types. A changeover relay is built with two circuits instead of one and five pins rather than four. Contact supplier request a quote. While a change over relay could be wired to be normally open no these normally open relays.
