Working Principles

ACPL-790A-000E utilizes an optocoupler configuration, consisting of an LED (Light Emitting Diode) as the input and a phototransistor as the output. When an electrical signal is applied to the input side, the LED emits light, which is then detected by the phototransistor on the output side. This optical coupling ensures electrical isolation while transmitting the signal.
