Working Principles

The ACPL-C870-500E utilizes an optocoupler to transmit signals between two circuits. It consists of an LED on the input side and a phototransistor or photodiode on the output side. When an electrical signal is applied to the input side, the LED emits light, which is then detected by the phototransistor or photodiode on the output side. This optical coupling ensures electrical isolation while allowing signal transmission.
