1C31219G01 Relay module is a semi-finished circuit board with an electronic control circuit added on the basis of the relay, which is provided to the user in the form of a circuit board. It can control high voltages using low voltages, and is often used in applications where low-power signals need to be isolated from high-power loads, such as home automation, industrial automation, automotive electronics, and more.

The working principle of the 1C31219G01 relay module is based on the electromagnetic principle. When electricity is applied through the coil, an electromagnetic field is generated, which attracts the iron core (or magnetic material) in the relay, causing the iron core to move under the action of the electromagnetic force. The movement of the iron core will cause the movement of the mechanical part, and finally make the contact (switch) action. There are two states of contact: normally open contact and normally closed contact. Normally open contact is in the open state when the relay is not powered on, and when the electromagnetic coil is powered on, the contact is closed. The normally closed contact is in the closed state when the relay is not powered on, and the contact is open when the electromagnetic coil is powered on.

In general, the 1C31219G01 relay module is a very important electronic component and plays an important role in electronic circuits.
