The Applications of Phoenix Contact PSR-SCP-24DC/URD3/4X1/2X2

1. Packaging Line Emergency Stop Control

In a modern packaging facility, ensuring a safe stop of conveyors, fillers, and labeling systems is critical. The PSR-SCP-24DC/URD3/4X1/2X2 module allows emergency stop buttons and door interlocks to extend safety signals to multiple machines. Its adjustable dropout delay ensures machines complete their current action before halting, preventing product spillage or mechanical lockups. By using force-guided relay contacts, the system detects faults immediately, reducing risks of undetected failures and guaranteeing compliance with global safety standards. This provides both protection for operators and consistent productivity on high-speed packaging lines.

2. Robotic Welding Cell Safety Integration

Automotive welding cells involve high energy, moving robots, and heat hazards. This extension module is integrated with guarding systems and light curtains to expand the reach of the main safety relay. When a gate is opened or a beam is broken, the module disables the welding circuit after a configurable short delay, allowing power to shut down in a controlled manner. Its signaling path alerts operators or supervisory systems to the trigger event, enabling quick intervention. By ensuring outputs are force-guided and monitored, manufacturers maintain the highest level of safety while still keeping robots productive.

3. Injection Molding Machine Guarding

Plastic injection molding machines require reliable interlocking to protect workers from moving clamps and heated tooling. The module provides delayed enabling outputs for drives and injection systems, allowing machinery to stop in a staged and controlled process. This avoids tooling damage and prevents hydraulic surges when a guard door is opened unexpectedly. Its confirmation path helps ensure every stop signal has been correctly transmitted. The compact 22.5 mm width saves cabinet space, making it ideal for crowded control panels in molding operations where precision and reliability are essential.

4. Conveyor Systems in Food Processing

Large-scale conveyor systems in food plants must balance operator safety with continuous material flow. The PSR-SCP-24DC/URD3/4X1/2X2 supports synchronized shutdown of conveyor motors when safety gates are opened or jams occur. The dropout delay function ensures belts slow to a halt without sudden stops that could cause product pile-ups. A confirmation contact monitors system integrity, ensuring every shutdown command is executed properly. With strong insulation and robust design, the module withstands challenging conditions such as humidity and electrical noise, keeping production lines safe and efficient while minimizing costly downtime.
