The Applications – Phoenix Contact PSR-PC32-2NO-1NC-24-230UC-SC Coupling Relay
1. Safety Gate Control in Automated Packaging Lines
In packaging and conveyor systems, access doors and safety gates must remain locked while machinery operates. The PSR-PC32 relay ensures these safety interlocks communicate correctly with the controller. Its force-guided contacts verify both contact movement and signal integrity, preventing machine start-up if a gate is open or wiring fails. With dual enabling paths and a confirmation channel, the system gains redundancy for dependable operator protection. The compact design allows quick DIN-rail installation inside tight control panels, keeping space use efficient without compromising safety.
2. Light Curtain Safety Interface for Robotic Work Cells
Industrial robots require fast reaction to human intrusion for operator safety. The PSR-PC32 coupling relay connects light curtain sensors to main control systems, immediately cutting power when a beam break occurs. Its wide 24–230 V AC/DC input range supports integration across different control standards. Built-in LED indicators simplify troubleshooting and maintenance during production, minimizing downtime. The SIL 3 safety certification ensures consistent and verifiable protection, making it an ideal component for modern robotic cells in automotive or electronics assembly lines.
3. Process Safety Isolation in Chemical and Energy Plants
In chemical or refining operations, safe shutdown control is vital to protect personnel and equipment. The PSR-PC32 relay provides galvanic isolation between safety instrumented systems and field actuators, ensuring signal integrity even under electrical noise or overload. Its corrosion-protected PCB and temperature tolerance from –40 °C to +70 °C make it suitable for harsh plant environments. The confirmation path adds verification feedback, enabling operators to confirm that shutdown commands are executed safely and fully, reducing the risk of equipment damage or hazardous releases.
4. Elevator and Lift Door Interlock Systems
Elevator control units depend on reliable verification that doors are closed and brakes engaged before movement. The PSR-PC32 relay supports this safety logic through redundant contacts that transmit and confirm status signals. The force-guided mechanism prevents simultaneous closure of conflicting contacts, safeguarding against short circuits or false positives. Its compact 17.5 mm housing and DIN-rail mount allow easy integration into multi-relay panels. By ensuring precise and fail-safe switching, the relay enhances passenger safety and meets stringent building automation standards.
