Hello, today I'd like to talk to you about the contact form of Suzhou relay. In Suzhou, a region where the economy is booming, many people know about Suzhou relay. Suzhou relay technology is at the forefront of the industry.
Relay (English name: relay) is an electrical control device, which can make the predetermined step change in the electrical output circuit when the input (excitation) change reaches the required requirements. It has the interaction relationship between the control system (also called the input loop) and the controlled system (also called the output loop). Usually used in automatic control circuit, it is actually a small current to control the "automatic switch" operated by large current. Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.
There are three basic forms of relay contacts:
1. When the movable (long open) (H) coil is not powered on, the two contacts are disconnected, and when the power is turned on, the two contacts are closed. It is represented by the pinyin "H".
2. When the dynamic disconnection type (Changbi) (D) coil is not energized, two contacts are closed, and the two contacts will be disconnected after being energized. Use the pinyin "D" to express in the deciphered words.
3. Conversion type (Z type) This is a contact configuration. There are three contact points in the contact group, namely the active contact point in the middle and a static contact point at the top and bottom. When the coil is not energized, the dynamic contact and one static contact open and the other close. After the coil is energized, the moving contact moves to make the original broken wire closed and off, so as to achieve the purpose of conversion. This contact group is called transfer contact. "Z" is represented by the pinyin head of the word "Zhuan".
