Description
Foxboro AD908JS
Technical Specifications
- Product Type: Pre-Terminated Communication Cable.
- System Compatibility: Foxboro I/A Series FBM.
- Connector Type: Proprietary Foxboro fieldbus connectors.
- Cable Type: Shielded, twisted-pair industrial communication cable.
Functional Features
- Plug-and-Play: Pre-terminated and tested to eliminate field wiring errors and reduce installation time.
- Signal Integrity: High-quality shielding protects against electromagnetic interference (EMI) and radio frequency interference (RFI).
- Durability: Ruggedized construction for long-term reliability in industrial environments.
- Strain Relief: Integrated strain relief boots protect the cable-to-connector interface.
Application Scenarios
Used in control cabinets to connect FBM cards to their corresponding field wiring terminal blocks, ensuring reliable communication in process control, power generation, and manufacturing facilities.
Performance Parameters
- Data Rate: Supports high-speed fieldbus communication.
- Impedance: Controlled impedance for minimal signal reflection.
- Shielding Effectiveness: High attenuation of external noise.
Material Composition
Conductors are made of high-purity copper. The insulation and outer jacket are made of flame-retardant, oil-resistant PVC or similar industrial-grade material. Connectors feature gold-plated contacts for low-resistance connections.
Structural Characteristics
A multi-conductor, shielded cable with molded connectors at both ends. The cable is typically flat or rounded for easy routing in cable ducts. Includes clear labeling for easy identification.
Working Principle
Provides a dedicated physical layer path for digital signals to travel between the FBM and the terminal assembly. The twisted pairs cancel out magnetic interference, while the shield diverts electric field interference to ground.
Installation Requirements
Route the cable away from high-voltage power lines. Secure the cable with appropriate clamps, avoiding sharp bends. Ensure connectors are fully seated and locked.
Usage Precautions
- Do not cut or modify the pre-terminated connectors.
- Avoid pulling on the cable itself; handle by the connector body.
- Inspect the cable jacket for damage before installation.
