Principle of signal relay

Apply a certain voltage to both ends of the coil , A certain amount of current will flow through the coil , And then the electromagnetic effect , The armature will overcome the tension of the return spring and attract to the iron core under the action of electromagnetic force , So as to drive the moving contact and the static contact of the armature （ Normally open contact ） Imbibition . When the coil is de energized , The electromagnetic attraction disappears , The armature will return to its original position under the reaction of the spring , Make the moving contact and the original static contact （ Normally closed contacts ） Release . Pull in like this 、 Release , Thus, the conduction in the circuit is achieved 、 The purpose of the cut is . For relays “ Normally open 、 Normally closed ” contact , It can be distinguished in this way ： A static contact that is disconnected when the relay coil is not energized , be called “ Normally open contact ”; A static contact in the on state is called “ Normally closed contacts ”. Relays usually have two circuits , For low-voltage control circuit and high-voltage working circuit .

effect 1)

Expand the scope of control . for example , When the control signal of multi contact relay reaches a certain value , It can be in different forms of contact groups , Simultaneous connection 、 Disconnect 、 Turn on the multiplex circuit .

Zoom in 2)

for example , Sensitive relay 、 Intermediate relay, etc , With a very small amount of control , A circuit that can control a large amount of power .

Integrated signal 3)

for example , When multiple control signals are input to the multi winding relay in the specified form , After comparison and synthesis , Achieve the predetermined control effect .

4) Automatically 、 remote control 、 monitoring

for example , The relay on the automatic device works with other electrical appliances , It can form a program control circuit , So as to realize automatic operation .
