  • How to divide the relay into AC and DC

    A relay is an electrical control device. It is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches the specifi...

  • How to distinguish between AC relay and DC relay

    Choose DC relay or AC relay, many customers have a lot of confusion on their products. Customers often ask: My relay input is DC, and the output is AC; or the input I want is AC, and the output is DC; or DC to DC, AC to AC, will not work. Faced with ...

  • What Is The Difference Between Relay Control And Contactor Control

    The reason why there is "what is the difference between relay control and contactor control" is because there are both similarities and differences between the two. The difference between the two is that they rely on controlling the on and off of sma...

  • Why Doesn't The Relay Light Up?

    If the relay does not light, it means that the relay may not work. Generally, the red light of the intermediate relay indicates AC voltage, and the green light indicates DC voltage. When it is found that the relay does not light, it is necessary to u...

  • Diodes Or Resistors Designed In Automotive Relays

    Some automotive relays are designed with diodes or resistors built in. These devices help suppress coil voltage spikes and protect the electronic circuit. DIODE RELAY PROTECTIONWhen the voltage is removed and a relay is denergised the magnetic field ...

  • How Do Latching Relays Work

    A latching relay, which is a subtype of electromechanical or electromagnetic switch, commonly chosen in scenarios where the operator needs to control (either switch off or amplify) a large amount of current flow. The key components in a magnetic or ...

  • Differences Between Latching And Non-latching Relays

    Latching relays can be designed to operate using either a magnetic or a mechanical model. We’ve already touched on the fact that the core difference with latching relays, in comparison to other relay switch types, is their ability to hold and retain...

  • Latching Relays Are Bi-stable

    In the most simple terms an automotive relay is an electronically operated switch. The type most commonly used in the automotive industry is an electro-mechanically operated switch. They are found in all types of vehicles - cars, trucks, vans, traile...
