SUMMARY
Optoisolation is essential for preventing current from one part of a circuit from affecting another, particularly when interfacing high-voltage and low-voltage components. It is commonly employed in scenarios where different voltage supplies are utilized, such as +/- 15 V for logic circuits and 30 V for drive circuitry. This technique also facilitates a "floating ground," allowing independent grounding of circuit sections while maintaining communication.
