Product Overview

A solid state relay is a non-contact on-off electronic switch, in which two small terminals are input control terminals, and the other two terminals are output controlled terminals, one in and one out, with photoelectric isolation in the middle, and photoelectric coupling between input and output. .

When a DC or pulse signal is applied to the input terminal, the output terminal can be converted from the off state to the on state (blocking state when there is no signal), so as to control a large load. The whole device has no moving parts and contacts, which can be It realizes the same function as the commonly used mechanical electromagnetic relay.

Since the solid state relay is a non-contact switching element composed of solid components, it has the characteristics of reliable operation, fast switching speed, no noise, long life, small size, no spark, corrosion resistance, explosion-proof and vibration resistance compared with electromagnetic relays. It has a series of advantages such as small external interference, compatibility with logic circuits, strong anti-interference ability, fast switching speed and convenient use. It has been widely used in computer peripheral interface equipment, electric furnace heating and constant temperature equipment; numerical control machinery, remote control systems, industrial automation devices; signal lights, traffic lights, lighting stage lighting control equipment; instrumentation, medical equipment, Copiers, color expansion machines, rubber and plastic machinery, automatic washing machines; in addition, they are widely used in chemical, coal mines and other occasions that require explosion-proof, moisture-proof and corrosion-proof, and have become an ideal replacement product for relay families.
