The HCPL-0631-500E operates by using an LED to generate light on the input side. The LED is driven by the incoming electrical signal. The light then activates the phototransistor on the output side, creating an electrical signal that is isolated from the input.
The key components:
LED (Pins 1, 2, and 3): The LED emits light when a current flows through it, depending on the input signal. Phototransistor (Pins 5, 6, and 7): The phototransistor on the output side receives light from the LED, resulting in an electrical signal that can be used by the output circuit.This isolation prevents high voltages or spikes on the input side from affecting the output side, thereby protecting sensitive components and improving system stability.
