ITEM DETAILS -
An optocoupler, also known as an optoisolator, is an electronic component that transfers electrical signals between two isolated circuits by using light. It typically consists of an LED (light-emitting diode) that emits infrared light and a photosensitive device such as a phototransistor, photodiode, or photothyristor. When the LED is activated by an input signal, it emits light that is detected by the photosensitive device, which then generates a corresponding electrical signal in the output circuit. This allows the input and output circuits to be electrically isolated from each other, which helps to prevent high voltages or noise from being transferred.
