In packaging plants, moving conveyors and robotic arms require operator protection. Safety guards equipped with sensors are monitored through the relay’s N/C feedback path, while N/O contacts provide enabling signals for the system. If a guard door is opened, the force-guided design ensures the fault is detected and the machine stops immediately. This dual function simplifies wiring and reduces the number of components needed inside control cabinets, while ensuring safety standards are met consistently.
CNC machines need reliable emergency stop circuits to protect both operators and equipment. The coupling relay’s multiple N/O paths allow redundant circuits to shut down drives, while the N/C path confirms that the emergency stop has been activated. Even if a contact welds, the forced guidance prevents hidden faults from going unnoticed. With this arrangement, machine builders can maintain compliance with stringent safety certifications while minimizing the risk of unexpected hazards.
Robotic welding and assembly cells often use light curtains as protective barriers. The coupling relay provides enabling current paths when the barrier is clear, while the monitoring contact ensures system controllers receive reliable fault feedback. Because the relay can handle multiple enabling circuits, it supports several robot axes at once. Its high insulation strength and resistance to electrical surges also make it dependable in noisy environments such as welding areas, where electromagnetic interference is common.
In chemical or water treatment systems, valves must be securely closed in case of failure. The relay drives the valve actuator through its N/O contacts, while the N/C contact monitors whether the valve reached the closed position. If the actuator malfunctions, the feedback contact reveals the problem, triggering a safe shutdown or alarm. With long mechanical life and a robust 24 V AC/DC supply range, the relay performs reliably even in demanding, high-cycle industrial environments.
