It is a non-contact switching device with relay characteristics that uses semiconductor devices instead of traditional electrical contacts as switching devices. Single-phase SSR is a four-terminal active device, in which two input control terminals, two output terminals, and light between input and output. Isolation, when the input terminal adds a DC or pulse signal to a certain current value, the output terminal can be converted from an off state to an on state

Solid State Relay(abbreviated SSR), is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation between the control end and the load end uses photoelectric coupling or pulse signal. The input end of the solid state relay uses a tiny control signal to directly drive a large current load.
In addition to the same functions as electromagnetic relays, solid-state relays also have logic circuit compatibility, vibration resistance and mechanical shock resistance, unlimited installation positions, good moisture-proof, mildew-proof and corrosion-proof performance, and excellent performance in explosion-proof and ozone pollution prevention. , The input power is small, the sensitivity is high, the control power is small, the electromagnetic compatibility is good, the noise is low and the operating frequency is high. The solid state relay dedicated to the solid state relay can have the functions of short circuit protection, overload protection and overheat protection, and the combination logic curing package can realize the intelligent module required by the user, which can be directly used in the control system. Solid state relays have been widely used in computer peripheral interface equipment, constant temperature systems, temperature regulation, electric furnace heating control, motor control, numerical control machinery, remote control systems, industrial automation devices; signal lights, dimming, flashers, lighting stage lighting control systems; Instrumentation, medical equipment, copiers, automatic washing machines; automatic fire protection, security systems, and power capacitor switches used as power factor compensation for power grids, etc. In addition, there are a large number of explosion-proof, moisture-proof, and anti-corrosion occasions in chemical industry, coal mines, etc. use
