The function and principle of the relay

1. Therefore, it plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit. In the 1830s, American physicist Joseph Henry invented relays using electromagnetic induction when studying circuit control.

2. Working principle of the relay: When the relay is working, the electromagnet is energized, and the connecting iron is sucked down to make D and E contact, and the working circuit is closed. When the electromagnet is cut off, it loses its magnetism, and the spring pulls up the connecting iron to cut off the working circuit.It is actually an automatic switch that uses small current to control the operation of large current.

3. [Pacific Automobile Network] The main working principle of the relay is: when the change of the input quantity (excitation quantity) meets the specified requirements, it is an electrical appliance that makes the controlled quantity undergo a predetermined step change in the electrical output circuit. It has an interaction between the control system (also known as the input loop) and the controlled system (also known as the output loop).

4. Working principle and characteristics of electromagnetic relays. Electromagnetic relays are generally composed of iron cores, coils, connecting irons, contact reeds, etc.

What is a relay

What does ems relay mean

EMS (Electro Magnetic Susceptibility) means electromagnetic sensitivity. It refers to the degree to which the performance is easily reduced due to electromagnetic energy. For the sake of ease of understanding, we compare electronic devices to people, and compare electromagnetic energy to cold viruses. The sensitivity is whether they are prone to colds.

The full name of EMS is Emergency Stop System, which is a device used to quickly stop machines and processes in an emergency.

Relay is actually an "automatic switch" that uses a smaller current to control a larger current.

working principle and function of relay

It is actually an "automatic switch" that uses a smaller current to control a larger current.

Working principle of the relay: When the relay is working, the electromagnet is energized, the connecting iron is sucked down to make D and E contact, and the working circuit is closed. When the electromagnet is cut off, it loses its magnetism, and the spring pulls up the connecting iron to cut off the working circuit. It is actually an automatic switch that uses small current to control the operation of large current.

[Pacific Automobile Network] The main working principle of the relay is: when the change of input quantity (excitation quantity) meets the specified requirements, it is an electrical appliance that makes the controlled quantity undergo a predetermined step change in the electrical output circuit. It has an interaction between the control system (also known as the input loop) and the controlled system (also known as the output loop).

Therefore, it plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit. Because the relay is composed of two parts, the coil and the contact group, the graphic symbol of the relay in the circuit diagram also includes two parts: a long square represents the coil; a set of contact symbols represents the contact combination.

What is a relay and what is its function?

It is actually an automatic switch that uses small current to control the operation of large current.The functions of the relay include expanding the control range, amplification, integrated signal, automatic, remote control and monitoring.

Relay is an electrical controller, which is an electrical appliance that makes the controlled quantity undergo a predetermined jump change in the electrical output circuit when the change of the input quantity (excitation) meets the specified requirements. Relay is usually used in automated control circuits. It is actually an "automatic switch" that uses small current to control the operation of large current.

(2), zoom in. For example, sensitive relays, intermediate relays, etc. can control a large amount of power circuits with a very small amount of control. (3). Comprehensive signal. For example, when multiple controller signals are input into the multi-winding relay in the prescribed form, the predetermined control effect is achieved after comparison and synthesis.

The role of the relay The role of the relay has two main aspects: protection circuit and automatic control.Protection circuit: In the power system, relays are used to protect the circuit from overvoltage, overcurrent and other damage. When there is an abnormal situation in the circuit, the relay will act quickly to cut off the circuit and prevent accidents.
