Relay manufacturers for everyone to popularize the knowledge of relays
Role of the relay:
Relays use a small current to control a large current for automatic adjustment, safety protection, and conversion circuits. In order to allow more friends to understand the related problems of relays, here is a popular science by relay manufacturers.
How the relay works:
When the change of the input quantity (excitation quantity) reaches the specified requirements, it is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop).

Type of relay
Relay manufacturers provide popular science for you. According to the working principle or structural characteristics of relays, they can be divided into electromagnetic relays, temperature relays, time relays, etc. Different relay junctions have different working principles and different functions, as follows:
Electromagnetic Relay:
An electrical relay that uses the suction effect of the current in the input circuit between the electromagnet core and the armature.
Temperature relay:
A relay that works when the external ambient temperature reaches a certain value.
Time Relay:
When the input signal is added or removed, the output part needs to be delayed or limited to a specified time before closing or opening its controlled circuit relay.
The relay manufacturer tells you that although there are many types of relays, in summary, relays are used for automatic adjustment, safety protection, and conversion circuits.
