Detection of the eight legs of an optocoupler
We know from our tutorials about Transformers that they can not only provide a step-down (or step-up) voltage, but they also provide electrical isolation between the higher voltage on the primary side and the lo.

Identifying the pins of an optocoupler
How can I identify the input and output pins of an optocoupler? Refer to the optocoupler's datasheet or a circuit diagram. If a diagram is unavailable, carefully examine the physical layout and compare it to other. In this pinout diagram of PC817, pin1 and pin2 are parts of the input side and pin3 – pin4 are output pins. Apply a varying voltage to the input pin. If. Optocouplers, also known as opto-isolators, are components that transfer electrical signals between two isolated circuits by using infrared light. It typically consists of an LED (light-emitting diode) and a photodetector (such as a phototransistor) housed within a single package.
