Working Principles

The ACPL-C784-500E optocoupler consists of an infrared light-emitting diode (LED) and a phototransistor. When an electrical signal is applied to the input side, the LED emits light that is detected by the phototransistor on the output side. This optical coupling ensures electrical isolation between the input and output circuits while allowing for signal transmission.
