Case Study of Optical Coupler for Relay Protection

This circuit uses optocouplers paired with 220-ohm resistors to interface an Arduino Nano with an external device via a 5-pin relimate connector, providing electrical isolation and signal transfer while protecting the microcontroller. Optocouplers are used to isolate signals for protection and safety between a safe and a potentially hazardous or electrically noisy environment. The optocoupler uses light to transmit signals between its input and output. Optocouplers, also known as opto-isolators, uses infrared light to transfer electrical signals between two electrically isolated circuits and are commonly classified by their photosensitive output device What is an Optocoupler? An optocoupler (also called an opto-isolator, photo-coupler, or optical.
