Rated operating voltage It refers to the voltage required by the coil when the relay is working normally, that is, the control voltage of the control circuit. Depending on the type of relay, it can be either an AC voltage or a DC voltage. 2. DC resistance Refers to the DC resistance of the coil in t... read more
The principle of magnetic holding relay (detailed magnetic drive relay drive circuit diagram and wiring method), there are many classifications of relays, but the principle of most relays is the same. Compared with ordinary electromagnetic relays, magnetic retention relays have the advantage of low ... read more
1. Electromagnetic relay: An electrical relay that works by the suction force generated between the electromagnet core and the armature in the input circuit. 2. Solid state relay: A type of relay in which the electronic component performs its function without mechanical moving parts, and the input a... read more
The action of the contact can be divided into two parts: contact closure and contact disconnection, that is, the pull-in and release process of the relay, which are cyclically switched at a certain frequency to form a contact opening and closing phenomenon. There are many special physical and chemic... read more
A power relay is a device that can be converted in one or more electrical output circuits when input (or excitation) meets certain specific conditions. It can be used in a neutral point direct grounding system as a directional component for zero sequence current protection. The action of the contact... read more
