The use of relays in our home is very important, which can provide the most basic life guarantee for home life. However, we should also pay attention to the use of relays to avoid unnecessary troubles. Then what is the function and principle of relay, and the correct use of relay, do you understand? Now let's find out.
First, what is the function and principle of relay
The function of relay: it can increase the scope of the whole circuit, and achieve the purpose of controlling the high-power circuit, so that it can operate automatically. The principle of relay: when the input is at a fixed value, the working state can be changed, and the working state can be changed to avoid accidents.
Two, the correct use of relay
1. When using the relay, it should be used according to the instructions as far as possible, and each parameter should be within the prescribed range, so as to ensure sufficient safety. Moreover, the load and service time of relay cannot be determined, after all, it will change according to the surrounding environment and load.
2. If you plan to use DC relays indoors, you need to use rectangular waves to perform the work. Indoor use of AC relays requires the use of sine waves to perform the work. If you want the relay to be better used, do not let the relay be hit, otherwise it is very easy to damage the internal components.
3. During the use of the relay, the ambient temperature and humidity should be moderate, and the air should not contain more harmful gases. Otherwise, the use of the relay will be affected. If it is a relay that belongs to polarization, then the voltage properties of the coil should be taken into account to ensure that it can be used normally.

The new relay refers to the electromagnetic relay developed and produced in order to meet the new special requirements and meet the use under special environmental conditions. Its main characteristics are small volume, light weight, vibration resistance, shock resistance, load range from low level load to 5A, 28V rated load, and the product has reliability index (failure rate level) requirements. The product adopts resistance fusion welding or laser fusion welding sealing air-tight sealing structure, mainly used in electronic control equipment signal transmission and weak current power switching.

There are many types of relays, which can be divided into voltage relay, current relay, time relay, speed relay and pressure relay according to the input quantity, electromagnetic relay, induction relay, electric relay and electronic relay according to the working principle, and control relay and protection relay according to the purpose. According to the input quantity change form can be divided into whether there is a relay and measuring relay.

The relay coil is represented in the circuit by a long box symbol, and if the relay has two coils, two long boxes are drawn side by side. At the same time, mark the relay word symbol "J" in or beside the long box. There are two ways to represent the contacts of relays: one is to draw them directly on one side of the long box, which is more intuitive.

Measure contact resistance: use the electric barrier of a multimeter to measure the resistance of normally closed contact and moving point, and the resistance value should be 0; The resistance of normally open contact and moving point is infinite. So you can tell that one is a normally closed contact and that one is a normally open contact.
