• 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...

  • What is the structure of automotive relays

    Automotive relays are widely used to control car startup, preheating, air conditioning, lights, wipers, EFI, fuel pumps, anti-theft, audio, navigation, electric fans, cooling fans, electric doors and windows, airbags, anti-lock brakes, suspensions In...

  • What are the principle characteristics of electromagnetic relays

    Electromagnetic relay is an electronic control device. It has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. It actually uses a smaller current and ...

  • What is the difference between time relay and speed relay

    The time relay is a kind of delay control relay. It does not make the contacts act immediately after receiving the action signal, but delays for a period of time to make the contacts act. Time relays are mainly used in various automatic control syste...

  • Where is solid state relay better than electromagnetic relay

    1. Longevity and high stabilityIn fact, the life of mechanical contacts determines the life of mechanical relays. Since there are no mechanical contacts inside the solid-state relay, the service life of the SSR relay will not be shortened by the stra...
