Photoelectric isolator: The device is also called a photocoupler, or optocoupler for short. Optical couplers use light as a medium to transmit electrical signals. It has a good isolation effect on input and output electrical signals.The main advantages of optocouplers are: signal transmission in one direction, electrical isolation at the input end and output end, the output signal has no effect on the input end, strong anti-interference ability, and stable operation.
