Hello friends, I hope you all are doing great. Today, I am going to share the new PC817 Optocoupler Library for Proteus . An optocoupler joins two circuits with nothing but light: an infrared LED on one side, a phototransistor on the other, and a clear gap between them that can hold off thousands of volts. It is how a 3.3 V or 5 V microcontroller reads a 24 V machine signal, how it switches a load on another supply without sharing its ground, and how a mains power supply tells its controller what the output is doing.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to PC817. PC-817 is also known as an optocoupler / optoisolator. It consists of Infrared Emitting Diode (IRED). This IRED is coupled to a photo transistor optically and not electrically. It is closed in a four (4) pin package. This package is usually available in two different forms. The first one is wide lead (Pb) spacing option and the second one is SMT gullwing lead form option.
