The Applications of Phoenix Contact PSR-SCP-24UC/THC4/2X1/1X2

1. Operator Safety in Mechanical Presses

Mechanical presses pose significant risk if an operator’s hand enters the danger zone during operation. With a two-hand control relay, activation only occurs when both hands press separate buttons within a strict timing window. If one hand is released, the relay immediately disables outputs, halting the press. The PSR-SCP ensures this through fast synchronous monitoring and dual enabling paths, preventing unsafe single-hand triggers. Its compact size simplifies integration into existing panels while still meeting demanding SIL 3 and PL e standards. This balance of reliability and safety makes it ideal for retrofit or new installations in high-risk press operations.

2. Sheet-Metal Cutting Lines

In sheet-metal cutting processes, operators must frequently feed material close to moving blades. The PSR-SCP safety relay requires both hands on separate controls before allowing blade movement, eliminating the chance of one hand being exposed during operation. Its signaling output can connect to machine status displays, improving operator awareness and reducing mistakes. Force-guided contacts provide dependable switching, while safe isolation protects wiring circuits from electrical hazards. By enforcing two-hand operation and offering quick stop response, the device effectively reduces accidents in cutting applications where precision and operator safety are equally important.

3. Automated Assembly Stations

Assembly lines often involve presses or powered tools where an operator might need to hold components in place. The PSR-SCP relay ensures that tools only function when both hands are firmly on the controls, preventing accidental starts during alignment. With rapid release times, the tool stops immediately once buttons are released, keeping workers safe during fast production cycles. Clear LED indicators on the device provide quick status feedback, helping operators and supervisors stay confident in safe operation. Its durable design, combined with DIN rail mounting, supports continuous use in demanding environments without compromising productivity.

4. Punching and Stamping Machines

Punching and stamping machines apply high forces at high speeds, creating serious hazards if activated unexpectedly. The PSR-SCP relay eliminates this risk by requiring two-hand control with synchronized activation. Its redundant channels detect faults in the wiring or control circuit, ensuring that any failure results in a safe lockout. With two enabling outputs and one signaling output, it integrates smoothly into complex safety systems. Built for long service life and tested to Category 4, PL e, and SIL 3 standards, it provides manufacturers with confidence that worker safety is fully maintained during heavy-duty stamping operations.
