Solid-state relay (SOLIDSTATERELAYS, hereinafter abbreviated as "SSR") is a new type of non-contact switching device composed of solid-state electronic components. It uses the switching characteristics of electronic components (such as semiconductors such as switching triodes and triacs). , Can achi... read more
Because solid state relays have no mechanical contacts and other mechanical parts, their reliability is very high. The solid-state relay does not generate electric sparks and has no noise at the moment of on and off. Its switching speed is quite fast and the operating frequency is also quite high. T... read more
Dedicated solid state relays can have short-circuit protection, overload protection and over-temperature protection functions, and combined with logic-cured package to realize the intelligent modules required by users, directly used in the control system. Solid state relays have been widely used in ... read more
Time relay principle: Air-damped time relays are often used in AC circuits, which use the principle of air throttling through small holes to obtain delayed action. It consists of three parts: the electromagnetic system, the delay mechanism and the contacts. Wiring method for time relay: 1. Control w... read more
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
