A Safety Isolated Relay is a type of relay designed to provide electrical isolation between different parts of an electrical circuit, particularly between low-voltage control circuits and high-voltage or high-current load circuits. The primary function of these relays is to protect sensitive components or systems from electrical faults such as short circuits, surges, and overloads. By isolating the control and load circuits, safety isolated relays ensure that an electrical fault in one part of the system does not cause damage to other areas.

    The core feature of a safety isolated relay is its ability to "break" the electrical connection between the control and power circuits through a physical or electrical barrier. This barrier could be a mechanical relay contact, a solid-state device, or an optical isolator like a phototransistor. By doing so, it prevents potential damage and provides a higher level of safety for both the equipment and personnel working with or around the system.
