The Applications of Phoenix Contact PSR-SPP-24DC/FSP/2X1/1X2 Coupling Relay

1. Safety Valve Control in Chemical Plants

In chemical production, safety valves must respond instantly to prevent dangerous leaks or overpressure conditions. The PSR-SPP-24DC/FSP/2X1/1X2 ensures secure operation by coupling failsafe controller outputs to valve actuators with dual enabling paths. Its test pulse filter prevents spurious activations during diagnostic checks, maintaining stability in demanding environments. The compact housing allows installation in already crowded cabinets, while the SIL 3 certification provides the level of safety required in high-risk industries. By using this coupling relay, operators achieve reliable shutdown of safety valves, reducing the chance of accidents and ensuring compliance with strict international process safety standards.

2. Conveyor Emergency Stop Integration in Manufacturing

In automated manufacturing, conveyors are vital but must stop immediately during emergencies. The PSR-SPP-24DC/FSP/2X1/1X2 enables dependable connection between emergency-stop buttons, safety controllers, and motor drives. With force-guided contacts, it prevents undetected faults that could compromise safety. The integrated signal contact allows proof testing without halting production entirely, giving maintenance teams the ability to confirm system integrity quickly. Its robust isolation shields controllers from electrical noise generated by motors, avoiding false trips. Compact and reliable, this coupling relay ensures that when an emergency-stop command is triggered, conveyor lines shut down consistently, protecting personnel and preventing costly equipment damage.

3. Elevator Door Lock Monitoring in Building Automation

In elevator systems, doors must remain securely closed before the cabin moves. The PSR-SPP-24DC/FSP/2X1/1X2 adds a critical layer of reliability by interfacing the safety logic with the door lock actuator. Its fast switching response ensures faults are detected and acted upon before unsafe movement can occur. The redundant enabling paths increase fault tolerance, while the compact 17.5 mm width allows easy integration into control cabinets with limited space. Designed for SIL 3 applications, the relay meets the stringent requirements of building safety regulations. By using this coupling relay, elevator systems maintain operational safety while ensuring compliance with industry standards.

4. Rail Signal Control & Level Crossing Barriers

In railway systems, safety at crossings and signal points is critical to prevent accidents. The PSR-SPP-24DC/FSP/2X1/1X2 is ideal for coupling railway interlock logic with actuators controlling barriers and warning lights. Its reinforced insulation and dual current paths protect signaling circuits from external faults while ensuring barriers respond reliably. The relay’s switching capacity supports inductive loads from motors commonly used in crossing mechanisms. Meanwhile, the test pulse filter allows continuous system diagnostics without false triggering. This combination of features ensures that railway operators can achieve consistent, safe performance while meeting rigorous safety requirements, maintaining both passenger safety and network reliability.
