will fail to start. If the ignition switch relay is broken, the car will not start, and if the power window relay is broken, the car's power windows will not be able to raise and lower. There are multiple relays on the car that control multiple lines...
As one of our common switching devices, relays belong to a class of controllable switches. Relays are widely used, especially in electrical control. Since there are more than one or two types of relays, they are sometimes confused. Next, let's learn ...
The difference between the current relay and the voltage relay in structure. Mainly the coils are different. The coil of the current relay is connected in series with the load to reflect the load current, so the number of coil turns is small and the ...
First, understand the necessary conditions: 1. The power supply voltage of the control circuit and the maximum current that can be provided; 2. The voltage and current in the controlled circuit; 3. How many groups and what form of contacts are requir...
A relay is an electrical control device, which is an electrical appliance that makes a predetermined step change in the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) reaches the speci...
For electromagnetic (voltage, current, intermediate) relays, the sensing mechanism is an electromagnetic system. The faults of the electromagnetic system are mainly concentrated in the coil and the moving and static iron cores. (1) Coil Troubleshooti...
The technical parameters of the main products of the relay have five aspects. 1. Rated working voltage It refers to the voltage required by the coil when the relay is working normally. Depending on the model of the relay, it can be either AC voltage ...
Magnetic latching relays are very similar to polarized relays, with two static contacts, one moving contact, and multiple coils, which are equivalent to a "bistable relay" (which can also be regarded as a "current-driven" SPDT switch") The polarized ...
