Relay: "Magician" in Circuit

Relay is a magical electrical control device, which plays an important role in the circuit. In this paper, the internal structure and multiple functions of relay will be discussed in depth to help readers better understand the "magician" in this circuit.

Simple connection

Installing the relay is very simple, just press the pin to connect it directly.

Multiple roles

Relays play multiple roles in the circuit, including automatic adjustment, safety protection, conversion circuit and so on. To ensure the stable operation of the circuit.

♂? A man of extraordinary strength

In the automatic control circuit, the relay is like a "Hercules", which can easily control the operation of large current with small current and is as flexible as an automatic switch.

Exquisite structure

The internal structure of relay is quite exquisite, including induction mechanism, actuator and driving part. The induction mechanism senses the change of input variables, the execution mechanism controls the on-off of the controlled circuit, and the driving part plays the role of coupling isolation, function processing and driving output.
