What is the use of the relay?

Answer:

1 isolation, so that the control signal and the controlled signal isolation 2 control of large energy, you can use tens of milliwatts - tens of watts of power, control a few hundred watts - tens of kilowatts or more power (high current contactor) 3 control different forms of load, available DC, AC control AC, DC or other electrical signals

4 plus additional devices, can achieve a variety of functions, such as delay, short circuit protection, overcurrent protection, additional switching signal 5 remote control, remote control through a small cable signal, wireless signals, control the remote large equipment 6 Through the combination of relay contacts, you can achieve a variety of control functions, such as bistable.

The relay is an electronic control device, it has a control system (also known as the input circuit) and the control system (also known as the output circuit), usually used in automatic control circuit, it is actually a small current to control the larger A "automatic switch" of the current. So in the circuit plays an automatic adjustment, security protection, conversion circuit and so on.
