10a 24vdc relay working principle

10a 24vdc relay belongs to a classification of relay products, and it also has certain requirements for the environment in which it is used and operated. So the popular knowledge today is about the working principle of 10a 24vdc relay and the content of reference value in power calculation. Friends who are interested can learn from the actual situation.

1. What is the power of the 10a 24vdc relay coil?

The coil current of 10a 24vdc relay is about 30 to 70mA, and the typical value is 45mA.

2. Working principle of 10a 24vdc relay

The working principle of 0a 24vdc relay is generally composed of iron core, coil, armature, contact reed, etc. 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. When the coil is de-energized, the electromagnetic attraction will also disappear, and the armature will return to its original position under the reaction force of the spring, releasing the moving contact and the original static contact (normally closed contact). This pulls in and releases, so as to achieve the purpose of conducting and cutting off in the circuit. Regarding the relay's "normally open and normally closed" contacts, it can be distinguished as follows: 0a 24vdc relay The static contact that is in the off state when the coil is not energized is called "normally open contact"; the static contact that is in the on state The points are called "normally closed contacts".
