  • What is the function of the voltage relay

    A voltage relay is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.Voltage relay structure and prin...

  • How does a voltage relay work

    Electromagnetic relays are generally composed of iron cores, coils, armatures, contact reeds, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow in the coil, resulting in an electromagnetic effect, and ...

  • Composition of basic structural components of automotive relays

    It is composed of the basic structural components of an automobile relay. The relay builds a communication bridge between the blocked or isolated circuits in the circuit so that the current can flow and the circuit can realize the predetermined funct...

  • Four functions of electromagnetic relay module

    Electromagnetic relays are generally composed of iron cores, coils, armatures, contact reeds, etc. As long as a certain voltage is applied to both ends of the coil of the relay module, a certain current will flow through the coil, which will produce ...

  • What is an intermediate relay

    Intermediate relays are used in relay protection and automatic control systems to increase the number and capacity of contacts. They are also used to transmit intermediate signals in control circuits. The structure and principle of the intermediate r...
