  • What are the classifications of relays in electrical control equipment

    1. General purpose relay Such relays are further divided into electromagnetic relays and solid state relays, which not only play a protective role and function but also play a switching role. First of all, as a general purpose relay, the electromagne...

  • What is the magnetic latching relay

    A latching relay is a switching device that possesses a magnetic field that acts on an input signal to switch the state of the circuit. These devices can be used for a variety of applications. These devices are characterized by a number of features t...

  • What are electromagnetic relays

    An electromagnetic relay is a device that can switch two different electrical currents with the help of magnetic fields. These devices usually consist of a multiturn coil wound on an iron core and are used to switch various electrical and electronic ...

  • What is the difference between a circuit breaker and a contactor

    The circuit breaker is protective, can extinguish the arc, and has the ability to segment. The contractor uses the coil to control the on-off of the circuit. After the contactor is energized, the normally open is closed, and the long-closed is opened...

  • Troubleshooting Method for High Noise in AC Contactor Operation

    The noise of the AC contactor in operation is very large, which can be dealt with as follows: 1. The power supply voltage is insufficient, and the suction force of the electromagnet is not enough to generate noise. Try to increase the voltage of the...

  • What are the basic structural components of automotive relays

    The relay sets up a bridge of communication between the blocked or isolated circuits in the circuit so that the current flows and the circuit achieve the predetermined function. Basic structural components of automotive relays 1. The shell, also kno...

  • How to choose an electromagnetic relay

    Depending on the application, the electrical power you are using, and the size and functionality of the device, you can choose between different types of electromagnetic relays. You can even buy one that will come with a one-stop learning guide.  To ...

  • How to use a latching relay

    The latching relay is a type of electrical switch. It has input and output terminals and is applicable for circuit control and single or multiple control signals. There are two types of latching relays - magnetic and static. Read on to learn about ea...
