It plays the role of automatic adjustment, safety protection and conversion circuit in the circuit. Electromagnetic relays are generally composed of electromagnets, armatures, springs, contacts, etc., and their working circuits are composed of two pa...
Relay selection 1. Selection of voltage and current The selection should be based on the supply voltage of the control circuit and the maximum current that can be output, and then be selected according to whether the voltage and current of the contro...
The basic structure and working principle of the electromagnetic relay are similar to the contactor, which is composed of iron core, armature, coil, return spring and contact. Because the electromagnetic relay is used in the auxiliary circuit, its on...
The relay is a device that uses low-current voltage and weak current circuit to control high-voltage and strong current circuit. Electromagnetic relay is a switch that uses an electromagnet to control the working circuit. When the protected component...
Electromagnetic relay is an electronic control device. It has a control system (also called input loop) and a controlled system (also called output loop). It is usually used in automatic control circuits. It actually uses a smaller current. Applicati...
