The difference between relay module and contactor
(Summary description)Expand the scope of control. For example, when the control signal of a multi-contact relay module reaches a certain value, multiple circuits can be switched, disconnected, and connected at the same time according to different forms of contact groups.

The relay module mainly has the following functions:
1) Expand the scope of control. For example, when the control signal of a multi-contact relay module reaches a certain value, multiple circuits can be switched, disconnected, and connected at the same time according to different forms of contact groups.
2) Zoom in. For example, sensitive relays, intermediate relay modules, etc., with a very small control quantity, can control a circuit with a large power.
3) Integrated signal. For example, when multiple control signals are input to a multi-winding relay module in a prescribed form, they can achieve the predetermined control effect after comparison and integration.
4) Automatic, remote control and monitoring. For example, the relay module on the automatic device and other electrical appliances can form a program control circuit to realize automatic operation.
The function of the contactor is to use a small current to control a large current load, which can be remotely controlled, and can be self-locking and interlocked to prevent accidents caused by misoperation. Because of the small current control, the protection circuit is simple and reliable.
