Introduction to Optocoupler
An optocoupler, also known as an opto – isolator, 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 converts electrical input signals into light, and a photosensitive device (such as a phototransistor, photodiode, or photo – SCR) that detects the light and converts it back into an electrical signal. One of the key advantages of optocouplers is their ability to provide electrical isolation between input and output circuits, which helps in preventing electrical interference, voltage spikes, and ground loops. They are widely used in various applications, including power supplies, communication systems, industrial control systems, and automotive electronics. Optocoupler
