What is a general-purpose relay? General-purpose relay is a relatively abstract concept in physics. Many people may not understand what a general-purpose relay is. The relay is usually used in an automatic control circuit. It actually uses a small current to control high-current operation. An "autom... read more
The structure and working principle of the electromagnetic relay are similar to those of the contactor, and are mainly composed of an electromagnetic mechanism and a contact. Electromagnetic relays are also available in both DC and AC. The suction and release values of the relay can be adjusted with... read more
We will explain the working principle of the relay according to the example. The following figure is a diagram of a relay control bulb. The relay has a normally open contact and a normally closed contact. The movable contact is a common terminal. This is a smart home relay, that is, when the relay c... read more
The role of the car relay, the role of the relay, the relay function is to use the switch to control the relay coil, then the relay working contact is closed or open, the contact is connected to the main line current, and the other end is connected to the electrical appliance to be controlled to ach... read more
1. Signal relay The signal relay is a commonly used device in the automatic control system. It is generally used to turn the circuit on and off. It releases the control command and reflects the status of the device by dropping the card. After the device returns to normal, the signal is released by t... read more
