Tips: What is the function of the signal relay coil?
The function of the signal relay is that as long as a certain voltage is applied to both ends of the coil, a certain current will flow through it, thus producing electromagnetic effect. The armature will overcome the tension of the return spring and attract to the iron core under the action of electromagnetic force attraction, driving the moving contact of the armature and the static contact (normally open contact) to attract. However, the function of the coil is to make the coil charged through the input voltage to adsorb or bounce off the relevant contact point, in order to achieve mechanical opening or breaking another set of circuits, so as to achieve the desired output. Therefore the coil is the main component of the signal relay and plays an important role of electric energy into mechanical energy to achieve control. Since little current passes through the coil, the current or voltage controlled by the contacts is high, this will achieve the purpose of controlling large current and high voltage with small current or small voltage. When the signal relay coil is power off, the electromagnetic suction will disappear, and the armature will return to the original position in the spring reaction force, so that the moving contact and the original static contact (normally closed contact) attract. In this way, with suction and release, it will achieve the purpose of conducting and cutting in the circuit.
