Pin Function Table (8 pins):
Pin Number Pin Name Pin Function Description 1 Anode (A) The positive lead of the LED inside the optocoupler. It receives the input signal (current). 2 Cathode (K) The negative lead of the LED inside the optocoupler. It connects to ground and is used to complete the LED circuit. 3 NC (No Connect) This pin is unused and has no function in the circuit. It is left open. 4 GND Ground pin, used to connect to the ground of the circuit. 5 VCC Power supply pin for the output transistor side of the optocoupler. This pin should be connected to the positive voltage supply. 6 Collector (C) This is the collector of the output transistor. It is used to connect the output to the next stage in the circuit. 7 Emitter (E) This is the emitter of the output transistor. It is typically connected to ground or the low side of the circuit. 8 VCC This is a second VCC pin used to supply power to the optocoupler’s output transistor side.Circuit Principle:
The ACPL-P480-500E operates by providing electrical isolation between the input and output sections of the circuit. When current flows through the LED (Pins 1 and 2), it generates light that activates the phototransistor on the output side (Pins 6 and 7), thereby allowing the signal to be transmitted across the isolation barrier. This is the basic principle behind optocoupler operation, ensuring that high-voltage sections of the circuit remain isolated from low-voltage sections.
