PSC1-C-10-SDM1-FB2 10A Single Contact Interlock IP67 SS Modular Heavy Duty Flange Guard

1. Product Overview​

The Schmersal PSC1-C-10-SDM1-FB2 represents a fully integrated safety solution combining ​10-meter emergency stop cabling (C-10)​​ with the ​SDM1 diagnostic monitoring unit​ and ​FB2 dual-channel control unit. This system delivers SIL 3/PL e compliant emergency stopping with predictive maintenance capabilities for critical infrastructure. The FB2 unit features force-guided relays in an IP66-rated zinc housing, while the SDM1 adds real-time cable integrity analytics through integrated microprocessors. Stainless steel tension cables with polyurethane sheathing (UV-resistant RAL 1023 yellow) withstand oils, chemicals, and temperature extremes (-30°C to +80°C). Designed for kilometer-scale installations, it supports cascading configurations while maintaining <100ms stop response times. Continuous monitoring detects micro-fractures, elongation, and contact degradation before failures occur.

​2. Key Technical Parameters​

• ​Cable System: 10m Ø4mm AISI 316L core with PUR sheath, 70-180N adjustable tension
• ​Safety Ratings: ISO 13849-1 PL e (Cat. 4), IEC 62061 SIL 3
• ​Electrical:
  • Voltage: 24V DC to 230V AC ±10% (50/60Hz)
  • Safety Outputs: 2 NC contacts (10A/250V AC)
  • Diagnostic Outputs: 3 semiconductor channels (cable health/contact status/system fault)
• ​Monitoring Resolution:
  • Cable elongation detection: ±0.5mm
  • Strand break detection: >15% resistance change
• ​Environmental: IP66 (FB2)/IP69K (cable glands), -30°C to +80°C, 100m/s² vibration immunity
• ​Response: <100ms activation time, 500ms diagnostic scan cycle
• ​Connections: M20 entries with screw terminals (max 2.5mm²)

​3. Primary Applications and Use Cases​

This system is engineered for extreme environments where failure prevention is critical:

• ​Mining conveyors: Monitoring multi-kilometer runs with predictive cable replacement alerts
• ​Steel hot-rolling mills: Emergency stops along 200°C casting lines with thermal compensation
• ​Chemical tank farms: Perimeter protection in corrosive vapor zones
• ​Port loading arms: Providing emergency stops across articulating marine structures
• ​Airport baggage systems: Curved conveyor networks requiring elongation compensation
• ​Automotive test tracks: High-vibration emergency stops along robotic vehicle pathways
• ​Power plant coal handlers: Emergency trip systems in combustible dust environments
• ​Wastewater treatment: Cable systems resisting H₂S corrosion with ATEX compliance

​4. Product Advantages and Functional Benefits​

• ​Predictive Safety Analytics: SDM1 detects cable fatigue 6-8 weeks before failure
• ​Zero False Trips: Temperature-compensated tensioning (±0.05N/°C)
• ​Lifecycle Optimization: 60% cable lifespan extension through wear-based replacement
• ​Cyber-Resistant Design: Physical-only reset prevents remote manipulation
• ​Maintenance Efficiency:
  • Automatic tension logs via IO-Link (optional)
  • Quick-release cable splices for <10min segment replacement
• ​Harsh Environment Resilience:
  • Salt spray testing >1,000hrs (ISO 9227)
  • Hydrocarbon-resistant PUR sheath
• ​Compliance Simplified: Pre-certified templates for ISO 13850, ANSI B11.19, IEC 62061
• ​Redundancy Architecture: FB2 maintains safety function during single-component failure
• ​Global Certification: ATEX/IECEx Zone 21, UL Class I Div 2, SIL 3 TÜV report included

​5. Core Functionality and Diagnostic Integration​

Operation merges mechanical safety with Industry 4.0 diagnostics:
​Safety Activation:​​

1. Cable pull (≥70N) mechanically disengages FB2's spring-loaded latch
2. Force-guided contacts positively open within 100ms (Category 0 stop)
   ​Diagnostic Oversight (SDM1):​​

• ​Continuous Cable Monitoring:
  • Micro-Ohm resistance measurement detects strand fractures
  • Laser-engraved fiducials track sheath elongation with 0.5mm resolution
• ​Contact Surveillance:
  • Redundancy checks validate NC contact separation distance (>0.5mm)
  • Current monitoring detects contact welding precursors
• ​Fault Management:​​
  • Stage 1 alert (NO output): 15% cable elongation
  • Stage 2 lockout (NC output): Contact welding detected
  • Event logging: Stores last 20 faults with timestamps
    ​Reset Protocol:​​

1. Physical key turn at FB2 unit
2. SDM1 validation:
   a) Cable tension within 5% of calibration
   b) Contact resistance <50mΩ
3. PLC confirmation via diagnostic handshake
