A Safety Isolated Relay functions primarily by providing electrical isolation between its input and output circuits. The isolation ensures that high-voltage or noisy electrical signals do not interfere with the rest of the system, making it a vital tool in environments where system reliability and personnel safety are critical. By incorporating technologies like transformers or optical isolators, this relay maintains a secure separation between circuits, preventing damage and reducing the risk of malfunction.

    The main feature of a Safety Isolated Relay is its ability to disconnect the electrical supply to potentially dangerous equipment when a fault is detected. In doing so, it minimizes the risk of electrical hazards, like short circuits, overloads, or even fires. This safety feature is what sets it apart from standard relays, as it is specifically designed for high-risk applications.
