1769-ECR - 2-Port EtherNet/IP DFB Ring - Industrial Rugged Hot-Swap Network Module

The Allen-Bradley 1769-ECR Right-Hand End Cap is a critical structural and functional component for Rockwell Automation's CompactLogix™ 5370 and CompactGuardLogix™ control systems. Engineered to terminate I/O bus communication channels securely, it incorporates built-in diagnostic LEDs (PWR/RUN/NS) for real-time system status monitoring. With its zinc-alloy construction and IP20-rated protection, it withstands industrial vibration/shock while preventing electromagnetic interference.

• Bus Termination: Precision 120Ω resistor (0.1% tolerance) for CIP Safety™ networks
• Connector Security: M23 screw lock (0.6Nm torque) prevents disconnection under 50g vibration
• Diagnostic Indicators: Tri-color LED shows power (24V DC±10%), processor mode, and safety status
• Environmental: -20°C to +70°C operation / 92% max non-condensing humidity
• Bus Voltage: 5.25V DC regulated backplane power
• EMC Compliance: 30V/m RF immunity per EN 61000-6-2
• Isolation: Reinforced insulation (300V AC) between bus and chassis
• Safety Certifications: TÜV Rheinland SIL 3 (IEC 61508), PL e (ISO 13849)

• Robotic Workcells: GuardLogix™ safety controller termination for collaborative robots
• Packaging Machinery: Emergency-stop circuit termination meeting ISO 12100
• Chemical Processing: SIL-rated burner management system endpoints
• Material Handling: ASRS crane controller termination for IEC 62061 compliance
• Automotive Assembly: Safety light curtain interface termination
• Pharmaceutical: Washdown-rated isolator control panels (GMP Annex 1)
• Energy: Wind turbine pitch control safety backups

• Zero Downtime Locking: Slide-lock physically prevents module extraction without shutdown disables
• Predictive Maintenance: LED color sequences warn of capacitor aging pre-failure
• Space Optimization: 25mm profile saves panel depth for cramped enclosures
• Safety Validation: Embedded UL-recognized component marking simplifies audits
• Corrosion Defense: Chromate plating exceeds 500hr salt spray testing
• Takt Time Reduction: Tool-free installation cuts startup by 50% vs. hardwired ends
• Cost Savings: Eliminates $250+ external termination panels per system
