Optocoupler

Optocoupler (OC), also known as optoisolator, is a device that uses light as a medium to transmit electrical signals, usually encapsulating a light-emitting device (infrared light-emitting diode LED) and a photoreceptor (photosensitive semiconductor tube) in the same tube shell. When the input terminal is energized with a signal, the luminaire emits light, and the light receiver generates an electrical signal after receiving the light, and outputs it from the output terminal, thus realizing the "electricity-optical-electric" conversion. According to the output mode, the photocoupler can be divided into: photodiode output type, phototransistor output type, Darlington tube output type, photocyclist output type, logic gate circuit output type (gate circuit output type, Schmitt trigger output, totem pole output type, three-state gate circuit output type), power output type (IGBT/MOSFET output), etc. The main advantages of optocouplers are: the input and output terminals are completely insulated; The signal is transmitted in one direction, the output signal has no impact on the input terminal, and the anti-interference ability is strong; The input impedance of the optocoupler is smaller than that of the general interference source, so it has a strong common-mode rejection ability, and it can greatly improve the signal-to-noise ratio as a terminal isolation element in long-term transmission of information. As an interface device for signal isolation in computer digital communication and real-time control, it can greatly improve the reliability of computer work. Optocoupler is a photoelectric device developed in the 70s of the last century, and has been widely used in electrical insulation, level shifting, interstage coupling, driving circuits, switching circuits, choppers, multivibrators, signal isolation, pulse amplification circuits, digital instruments, long-distance signal transmission, solid-state relays (SSR), instrumentation, communication equipment and microcomputer interfaces.
