A Safety Relay is a specialized relay designed to monitor safety functions and ensure that hazardous machinery or systems stop in a controlled and safe manner when required. It is primarily used in circuits where high levels of protection are necessary to ensure the safety of personnel and equipment. Safety relays are most commonly employed in emergency stop circuits, safety door monitoring, light curtains, and other safety-related applications in industries such as manufacturing, robotics, and automation.

    The primary function of a Safety Relay is to monitor safety devices (such as emergency stop buttons, safety interlocks, or light curtains) and trigger a safe response, such as deactivating equipment, when a fault is detected or when an unsafe condition arises.
