An Opto-Splitter is specifically designed to provide electrical isolation between the control circuitry and the output devices in a lighting system. One of its primary functions is to prevent overvoltage situations from affecting sensitive components. By isolating the control signals, it ensures that any excessive voltage that may arise—such as those due to surges or spikes in the electrical system—does not travel back to the control source, which could otherwise damage the lighting control equipment or the connected fixtures.

In this context, overvoltage can be particularly problematic as it can lead to unexpected behavior in lighting systems or even catastrophic failure of the equipment. The Opto-Splitter mitigates this risk, making it an essential component in ensuring the longevity and reliability of lighting systems, especially in environments where fluctuating power conditions are common.

While voltage regulation, overcurrent, and frequency interference are important considerations in lighting systems, they pertain to different protective strategies and technologies. Voltage regulation focuses on maintaining output voltages within desired limits, overcurrent protection involves devices that cut off excessive current flow, and frequency interference deals with problems related to variances in signal frequency. An Opto-Splitter specifically addresses the risk of overvoltage, making it vital for protecting sensitive lighting control
