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
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
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
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
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
Relays are commonly used devices in automatic control systems, used to connect and disconnect circuits to form automatic control and remote control circuits. Whether as the core component of the relay signal system, or the interface component of the electronic or computer signal system, it plays an... read more
What is called a relay, a relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the input quantity (excitation quantity) changes to the specified requirements. When we ... read more
A power relay is a device that can produce a jump in one or more electrical output circuits when the input (or excitation) meets certain prescribed conditions, and can be used in a neutral point directly grounded system, as The directional element of zero sequence current protection. It has a wide ... read more
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
