• The basic principle of signal relay

    The signal relay (in the signal system, it can be referred to as the relay), it is composed of two parts: the contact system and the electromagnetic system. The electromagnetic system is composed of a coil, a fixed iron core, a yoke and a m...

  • How to judge the quality of various relays?

    1 When the solenoid coil is applied to the rated voltage of bai, it can normally pull in du, and it can be restored normally after power failure. When the coil is not energized, the dao normally closed contact should be well connected, and...

  • Classification of solenoid valves

    Classification of solenoid valves 1. According to the open structure can be divided into: pilot water valve, straight through water valve 2. According to the number of outlet: single valve, double valve, three valve, four valve and so on 3....

  • Applications and benefits of automotive relays

    Applications and benefits of automotive relays 1: Switch inge switching high current circuits: The most common application of automotive relays is to switch high-current circuits using low-current circuits. This application comes into play,...

  • DIODES & RESISTORS IN RELAYS

    Some automotive relays are designed with built-in diodes or resistors. These devices help to suppress coil voltage spikes and protect electronic circuits. Diode relay protection : When the voltage drops and the relay is de energized, the ma...

  • MICRO RELAY & STANDARD RELAY - WHAT'S THE DIFFERENCE?

    A micro relay is a smaller version of the more popular standard relay and are used when space is at a premium. Note, a standard relay is also sometimes referred to as a Mini Relay. Micro relays are more compact than the standard size and ar...

  • When to use on-off valves?

    Although any bang bang valve is a valve that moves between two different positions (open or closed), it also applies to valves with three positions, such as a 4 / 3 solenoid operated directional valve. But in some cases, a true on-off valve...
