PSC1-E-37-14D1-4D0-2R0-RI0 14/4-Contact Interlock IP67 Plastic Redundant Industrial Safety Switch

1. ​Product Overview​

The Schmersal PSC1-E-37-14D1-4D0-2R0-RI0 is an industrial-grade modular emergency stop system engineered for large-scale hazardous zones requiring extended cable runs and advanced diagnostics. This configuration features a ​37-meter stainless steel cable (E-series corrosion-resistant core)​​ with ​RI0 marine-grade coating​ for extreme environments. The ​14D1 control unit​ provides dual-channel safety monitoring with integrated diagnostics, while ​4D0 heavy-duty tensioners​ maintain precise cable tautness across long spans. Designed for SIL 3 applications, the system includes ​2R0 key-release reset functionality​ to prevent unauthorized reactivation. The zinc die-cast enclosure (IP66 rated) houses force-guided relays capable of interrupting high-current circuits. Modular splice kits allow cable extensions beyond 100 meters while maintaining <150ms emergency response times across the entire run.

• ​Precision Tensioning: 4D0 tensioners maintain ±2% force variance across 37m
• ​Diagnostic Intelligence:
  • Predictive cable replacement alerts
  • Contact wear monitoring
• ​Security Compliance: 2R0 key reset prevents unauthorized restart
• ​Seismic Resilience: Withstands 0.5g seismic loads (IEC 60068-3-3)
• ​Maintenance Optimization:
  • Hot-swappable cable segments
  • Splice kits for field repairs
• ​Global Certification: ATEX Cat 2D, UL 1203, IECEx Ex db IIC T6

5. ​Core Functionality and Safety Integration​

​Safety Activation:​​

1. Cable pull ≥150N anywhere along 37m span
2. Mechanical linkage releases 4D0 spring-loaded tensioners
3. Force-guided contacts positively open within 120ms
4. Dual NC outputs de-energize hazardous equipment

​Diagnostic Monitoring (14D1 Unit):​​

• ​Cable Integrity:
  • Micro-resistance measurement (accuracy ±0.1Ω)
  • Fiber-optic strain gauges detect 0.5mm elongation
• ​Contact Surveillance:
  • Separation gap verification (≥0.8mm)
  • Current signature analysis for welding precursors
• ​Environmental Compensation:
  • Automatic tension calibration for thermal expansion
  • Vibration filtering (5-500Hz)

​Reset Protocol:​​

1. Insert and turn safety key (2R0 mechanism)
2. System validation:
   a) Cable tension within 5% of setpoint
   b) Contact resistance <100mΩ
3. PLC confirmation via diagnostic handshake

​Fault Management:​​

• Stage 1: Diagnostic NO output signals 10% cable elongation
• Stage 2: Safety lockout triggers at 15% elongation or contact anomaly
• Event memory stores 50+ faults with millisecond timestamps
