In metal stamping facilities, press machines must be able to stop instantly to protect operators from injury. By using the PSR-SPP-24UC/URM/5X1/2X2, the emergency-stop button can reliably cut off the drive power through its force-guided contacts. This ensures that if one contact sticks, the feedback path still reveals the fault, preventing unnoticed failures. The relay’s rapid switching and compliance with safety standards allow presses to meet strict safety regulations, keeping both operators and equipment secure while minimizing downtime caused by undetected faults.
Material handling lines often require guards and access doors to prevent accidental entry into moving conveyor zones. This coupling relay allows interlock switches on safety doors to directly control the belt’s power circuit. The device’s combination of normally open and normally closed contacts ensures that a door left open, or a contact fault, is quickly recognized by the system. The compact design fits neatly into control cabinets, while its reliable fault detection supports continuous operation without compromising worker safety, making it an essential part of modern conveyor protection strategies.
Robotic welding stations pose risks from moving arms, sparks, and heat. Light curtains provide the first line of defense, but they require a trusted relay to carry the stop signal to the robot controller. The PSR-SPP-24UC/URM/5X1/2X2 excels here by using mechanically linked contacts that provide instant feedback if a switching failure occurs. This ensures the robot cannot resume operation if a fault is present. Its small housing saves cabinet space, while its robust safety certification gives integrators the assurance needed to meet global safety compliance in automated welding environments.
In chemical plants, safety valves must close reliably during conditions such as overpressure or overheating. This coupling relay provides a secure link between the process monitoring system and the valve actuator. With its force-guided contacts and SIL certification, it guarantees that if one output path fails, the failure will not go unnoticed. This feature is crucial in preventing hazardous leaks or equipment damage. Additionally, the relay’s durability and long service life make it suitable for harsh environments, ensuring critical shutdown functions operate correctly whenever needed, protecting both personnel and production assets.
