The Applications of Phoenix Contact PSR-SCP-24DC/ESD/5X1/1X2/300

1. High-Speed Packaging and Conveyor Systems

Modern packaging and sorting machines operate at high throughput, requiring precise safety control when guards or doors are opened. The PSR-SCP relay provides both instant and delayed shutdown paths, ensuring immediate protection while still allowing controlled stopping of conveyors or auxiliary units. Its dual-channel monitoring helps detect wiring or component faults, keeping the system compliant with strict safety standards. By adjusting delay times to match production speeds, operators can reduce false stops, improving uptime while maintaining a secure working environment.

2. Industrial Presses with Operator Two-Hand Control

Press machinery demands robust safeguarding to protect operators during stamping or forming cycles. The PSR-SCP relay verifies both input channels from two-hand controls, ensuring that the machine only cycles when both buttons are pressed simultaneously. Its force-guided contacts provide dependable fault detection, while the delayed outputs enable coordinated engagement of safety locks or barriers before the press begins. This combination enhances operator security, supports regulatory compliance, and minimizes the chance of accidental activation.

3. Chemical Handling and Spray Booth Systems

In facilities using volatile or hazardous substances, safe machine shutdown is critical when access points are opened. The PSR-SCP relay can provide undelayed interruption of power to pumps, fans, or agitators, while delayed contacts maintain ventilation or purging cycles for a set time. This ensures a safe environment without prematurely cutting processes that need controlled deactivation. Its SIL 3 safety rating guarantees reliable performance even in demanding industrial conditions, helping protect workers from exposure while safeguarding valuable equipment.

4. Food Processing Equipment with Safety Interlocks

Machines used in food production—such as slicers, cutters, and automated fillers—rely on protective doors and light curtains to prevent accidental access. The PSR-SCP relay supports one- and two-channel monitoring of these safety devices, ensuring redundancy and quick response to any fault. Instant contacts bring dangerous motion to a stop, while delayed contacts allow machine cycles to finish cleanly, preventing wasted product. Its compact design and wide environmental tolerance make it suitable for wash-down areas, providing consistent protection while supporting efficient production flow.
