Relay, also known as electric relay, is an electronic control device. It has a control system (also known as input circuit) and a controlled system (also known as output circuit).

Rated working voltage: refers to the voltage required by the coil when the 5 pin relay 24v works normally. Depending on the model of the relay, it can be either AC voltage or DC voltage.

It is not just the difference in raw materials that affects the price of 5 pin relay 24v. 5 pin relay 24v For users, the focus is nothing more than product price, product quality,

A relay is a current-controlled switching device. The working principle of the relay is that when the 5 pin relay 24v relay coil is energized, the iron core in the coil generates a strong electromagnetic force, and the armature is attracted to drive the reed
