What is the working principle of safety control relays

Electromagnetic relays are generally composed of iron cores, coils, armatures, and contact reeds. As long as a certain voltage is applied to both ends of the coil, a certain current will flow in the coil, which will produce electromagnetic effects. Under the action of electromagnetic force, the armature will overcome the pull force of the return spring and attract to the core, thereby driving the armature. The moving contact and the static contact (normally open contact) are pulled together.

Terminal function description
System module diagram
To sum up the application functions of safety control relays, relays have the following functions:

1) Expand the control range: For example, when the control signal of a multi-contact relay reaches a certain value, you can switch, break, and connect multiple circuits at the same time according to different forms of contact groups.

2) Amplification: For example, sensitive safety control relays, intermediate relays, etc., can control a circuit with a large power with a very small control amount.

3) Integrated signal: For example, when multiple control signals are input to a multi-winding relay in a prescribed form, they will achieve the predetermined control effect through comparative integration.

4) Automatic, remote control, and monitoring: For example, the relay on the automatic device and other electrical appliances can form a program control circuit to realize automatic operation.
