    What is a magnetic latching relay

    Magnetic latching relay is a new type of magnetic latching relay developed in recent years. It is also an automatic switch. Like other electromagnetic relays, it can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latchin... read more

    What are the differences between several common relays

    The relay is an automatic control device. When the input (electricity, magnetism, sound, light, heat) reaches a certain value, its output will undergo a jump change. We often use electromagnetic relays, single-phase relay, thermal relays and time relays. The principle and characteristics of the rela... read more

  • What are the advantages and disadvantages of solid state relays

    What are the advantages and disadvantages of solid state relays

    Solid state relays are non-contact electronic switches with isolation function. There are no mechanical contact parts during the switching process. Therefore, solid state relays have the same functions as electromagnetic relays, but also have logic circuit compatibility, vibration resistance and mec... read more

    What are the selection methods of solid state relays

    Selection method of solid state relay:1. When selecting solid state relays used on printed circuit boards with low current specifications, since the lead terminals are made of high thermal conductivity materials, the soldering should be carried out under the conditions of a temperature less than 250... read more

    What is the role of the intermediate relay

    The intermediate relay is a relay. Its principle is the same as that of an AC contactor. It is composed of a fixed iron core, a moving iron core, a spring, a moving contact, a static contact, a coil, a terminal and a shell. When the coil is energized, the moving iron core acts to pull in under the a... read more

    Why install a trip and lockout relay? What's the role

    Locking refers to "self-locking", which automatically locks the state of the relay after it is energized and keeps the loop connected, even if the control current is turned off at this time, it will not change its state.That is to say, when the power is turned on and the control current is turned of... read more
