Magnetic retention relay works: The magnetic holding relay is composed of a core, a coil, an armature, a contact spring, and the like. A certain voltage is applied to both ends of the coil, and a certain current flows through the coil, thereby generating an electromagnetic effect. Under the action o... read more
There are four test methods for single-phase relay. There are many test methods for power relays in common relays. Relays are also often used in various industries, such as automobiles, electrical and electronic products. The role of relays is to protect circuits. , limit the current, can achieve th... read more
Electromagnetic relays (EMR) have been in use for over 150 years since the initial use of telephone relays. Along with the development of the electronics industry, especially the breakthrough of optical coupling technology in the early 1970s, solid-state relays (SSRs, also known as electronic relays... read more
According to the principle of action 1. A relay that produces a predetermined response by the relative motion of mechanical components under the action of current in the input circuit. It includes DC electromagnetic relay, AC electromagnetic relay, magnetic holding relay, polarization relay, reed re... read more
1. According to the purpose classification, it can be divided into two types: functional type and control type relay. Flash relays such as wiper relays are functional relays, and ordinary relays that simply turn the circuit on and off are controlled relays. 2. According to the contact status, it is ... read more
