Definition of relay Relay is a kind of automatic control device [1] whose output will jump when the input (electricity, magnetism, sound, light, heat) reaches a certain value. The factory specializes in producing all kinds of time relays, electromagnetic relays, electronic relays, high-power relays, liquid level relays, solid-state relays, high-power relay small relays, timers, counters, relays, etc
Relay is essentially a kind of electrical apparatus that transmits signals. It achieves different control purposes according to the input signals. Relays are generally used to turn on and turn off control appliances (motors)
For example, the current relay in the DC motor, when the current is too small or too large, will control the start and stop of the motor after detecting this current signal |
