• 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...

  • 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 ...

  • 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...

  • Characteristics Comparison of PLC and relay

    In terms of application, plc uses microprocessor technology and communication technology, so it can be widely used in sequential control, motion control, communication, data management and other fields, and has extremely strong flexibility. However, ...

  • Application And Advantages Of Automotive Relays

    SWITCHING HIGH CURRENT CIRCUITS: The most common application of automotive relays is to switch a high current circuit using a low current circuit. This application comes into play whereby an in-line switch does not have the capacity to handle the cur...

  • Relay electrical symbols and contact form

    The relay coil is represented by a long box symbol in the circuit. If the relay has two coils, draw two long boxes in parallel. At the same time, the letter symbol "J" of the relay is marked inside or beside the long box. There are two ways to repres...

  • Electromagnetic relay structure and type

    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 lower current and lower cu...

  • What is the working principle of electromagnetic relay

    If the electromagnetic relay works in simple words, when the electromagnet is energized, the armature is sucked down to make the two contacts and the working circuit is closed. The electromagnet loses its magnetism when it is powered off, and the spr...
