2-Channel PLC Amplifier Board AC Output Thyristor Protection Board Bidirectional Optocoupler Isolation Board Contactless

SCR- Is short for thyristor rectifier components, is a four-layer high power semiconductor device with three PN junctions, also known as a thyristor.
It has small volume, relatively simple structure, strong function, high power control with low power, power amplification up to several hundred thousand times; fast response, open and close in microseconds; no contact operation, no spark, no noise, high efficiency and long life such as features
Optocoupler- photoelectric isolators or photoelectric optocouplers, also referred to as optocouplers
It is a device that transmits electrical signals by means of light. Generally, an illuminator (infrared light emitting diode (LED)) and a light receiver (photosensitive semiconductor tube) are packaged in the same package. When the input terminal adds a signal, the illuminator emits light, and after receiving the light, the photocurrent is generated and flows out from the output end, thereby realizing "electro-optical" conversion, and an optocoupler that couples the input signal to the output with light as a medium.
It has the advantages of small size, long life, no contact point, strong anti-interference ability, insulation isolation between output and input, one-way transmission signal, etc.
