A Safety Isolated Relay is a specialized type of relay designed to provide electrical isolation between different parts of an electrical system. It acts as a protective intermediary, ensuring that control circuits (often operating at low voltage) are electrically isolated from high voltage or power circuits. This isolation protects sensitive components and operators from electrical faults, such as short circuits or power surges, which could lead to system failure or even personal injury.

    The isolation in a Safety Isolated Relay is typically achieved through components such as opto-isolators, transformers, or magnetic isolation. This separation ensures that any fault occurring in one section of the system does not propagate to other sections, preventing widespread damage or failure. In essence, the Safety Isolated Relay serves as a "safety gatekeeper" within complex automation systems.
