The Schneider Electric/Invensys/Foxboro P0912CM is a dual coaxial cable assembly engineered for high-speed, redundant communication within Foxboro I/A Series and InFusion Enterprise Control Systems. It connects Processor Modules to Field Device Interconnects and facilitates node-to-node communication across Fieldbus and Nodebus environments, delivering minimal signal loss and superior EMI/RFI immunity in demanding industrial settings.
Technical Specifications
• Manufacturer: Schneider Electric / Invensys / Foxboro
• Model: P0912CM
• Product Type: Dual Coaxial Cable Assembly
• Impedance: 75 Ohms
• System Compatibility: Foxboro I/A Series Distributed Control Systems, InFusion Enterprise Control System
• Jacket Material: Industrial-grade, interference-resistant construction
• Design: Twin-axial arrangement
– Key Features
• Redundant Communication Paths: Dual coaxial design enables Path A and Path B operation. Automatic failover to the alternate path ensures uninterrupted process control if one path degrades or fails.
• Signal Integrity: Coaxial geometry maintains high signal-to-noise ratio in high-voltage environments without performance degradation.
• EMI/RFI Shielding: Industrial-grade construction provides robust immunity to electromagnetic and radio frequency interference.
• Bending Considerations: Avoid sharp bends; excessive bending radius stress can cause center conductor migration and intermittent faults.
– Typical Applications
• Processor-to-FBM backplane integration across distributed control architectures
• Cross-cabinet and adjacent-rack network expansion
• Redundant field device monitoring and control in mission-critical processes
– Compatibility & Integration
The P0912CM connects directly to Processor Modules (CPs), Field Device Interconnects (FDIs), and Fieldbus Module (FBM) backplanes within Foxboro I/A Series systems. Its 75 Ohm characteristic impedance and dual-path architecture align with Foxboro’s Fieldbus and Nodebus communication protocols, enabling transparent integration into existing control network topologies.
