Here’s a detailed description of the 16 pins in the SO-16 package:

Pin # Pin Name Description 1 Anode Anode of the LED (Light Emitting Diode ) inside the optocoupler. Connect to positive supply. 2 Cathode Cathode of the LED. Connect to negative side of the supply or ground. 3 No Connection No internal connection for the specified package. 4 Collector Collector of the photo transistor . This is connected to the output side of the optocoupler. 5 Emitter Emitter of the phototransistor. This connects to the signal side or ground. 6 Base Base of the phototransistor, often used for biasing to control its switching characteristics. 7 No Connection No internal connection for the specified package. 8 No Connection No internal connection for the specified package. 9 No Connection No internal connection for the specified package. 10 Base Another base of the phototransistor (similar to pin 6). 11 Collector Another collector of the phototransistor. 12 Emitter Another emitter of the phototransistor. 13 No Connection No internal connection for the specified package. 14 No Connection No internal connection for the specified package. 15 Vcc Power supply for the internal circuitry of the optocoupler. 16 GND Ground for the internal circuitry of the optocoupler.

Circuit Principle:

The ACPL-C87A-500E uses an internal LED to convert electrical signals into light and a phototransistor to convert the light signal back into an electrical signal. The LED side is typically connected to the input side of the circuit, and the phototransistor side is connected to the output side, effectively isolating the input and output signals while allowing the signal to pass through.
