| About the problem of car relay some people just understand car relay is equivalent to a switch, and through small current to control large current, do not know here knowledge big this! Here aifu relay is further complemented by car relays that are less well known in this field. The following text will hopefully give you a different spiritual experience. The same problem is that some people's words are always chicken soup, because that's the public mind, but some people can interpret it from different angles. The following is the expression of the problem of different automobile relay. Relays can be divided into single relay, double relay and multiple relay. Each relay has different functions. A single link is a single working relay. Twinned relays are relays that can work together or individually, as well as multiple relays. The relay is designed to intercept the flow and avoid burning the circuit. As to what kind of relays to use, that kind is much gone. Cars are generally small lights, near light, far light, horn, start, preheat, signal, wiper, air conditioning, lift, brake lights and so on. Basically, there are relays at the place where electricity is used. Not only in the car, but in the electronic circuits of any device, the relay switches another pair (or pairs) of larger contacts on (or off). The goal is to have a high current or high voltage to drive the load behind it. That's what the relay does; Other functions: 1. Isolation (mainly refers to strong or weak current, or ac or dc); 2. 2. Protection; If the display (high-grade) image, sound power amplifier output connected to the speaker (speaker), the use of the relay; 3. Step by step conversion; In electronic circuits, sometimes the control voltage or current is relatively high or large, the first level relay can not complete, then the use of a number of relay to transition. So much for car relays. More new questions about car relays are waiting to be discovered. | ||||
