It outputs the signal transmitted from the LED to the external circuit. 8 Output Transistor Emitter This is the emitter pin of the phototransistor inside the optocoupler. The phototransistor's collector-to-emitter resistance changes based on the input LED current.Circuit Principle and Operation of HCPL-0710-500E:
The HCPL-0710-500E is an optocoupler that operates based on light transmission between an LED and a phototransistor. Here’s how the circuit works:
LED Activation: When a current is applied to the anode and cathode (pins 1 and 2), the LED inside the optocoupler lights up. This generates light, which is the signal input to the circuit.
Signal Transmission: The light emitted by the LED is detected by the phototransistor inside the optocoupler. The phototransistor’s conductivity is modified based on the intensity of the light received.
Signal Output: The changes in conductivity of the phototransistor (pins 7 and 8) are transmitted as an electrical signal to the output side of the circuit. This allows electrical isolation between the input and output circuits, with the optocoupler ensuring that there is no direct electrical connection between the two.
