Description
Foxboro F3322Z7316
Technical Specifications
- Product Type: Pre-Terminated Wiring Harness Assembly.
- System Compatibility: Foxboro I/A Series FBM.
- Connector Type: Proprietary high-density FBM connectors.
- Cable Type: Shielded, multi-conductor industrial control cable.
Functional Features
- Plug-and-Play Installation: Pre-terminated and tested to eliminate field wiring errors and drastically reduce installation time.
- Signal Integrity: High-quality shielding protects against electromagnetic interference (EMI) and radio frequency interference (RFI).
- Strain Relief: Integrated strain relief boots protect the cable-to-connector interface from mechanical stress.
- Clear Identification: Factory-printed wire labels for rapid troubleshooting and maintenance.
Application Scenarios
Deployed in control cabinets across oil & gas, chemical, and power generation industries to interface FBM cards with field wiring terminal assemblies.
Performance Parameters
- Dielectric Strength: High insulation resistance to prevent signal leakage.
- Current Rating: Sufficient ampacity for standard industrial control signals and loop power.
- Operating Temperature: Rated for continuous operation in harsh industrial environments.
Material Composition
Constructed with high-purity, tinned copper conductors for excellent conductivity. The outer jacket is made of flame-retardant, oil-resistant PVC or PUR. Connectors feature gold-plated contacts for low-resistance connections.
Structural Characteristics
A multi-conductor, shielded cable with precision-molded connectors at both ends. The assembly is designed for neat routing in cable ducts and includes a ruggedized outer jacket for physical protection.
Working Principle
The harness acts as a passive electrical bridge, providing a dedicated, low-impedance path for electrical signals and power to travel between the FBM’s backplane connector and the field devices. The shielding continuously diverts external electrical noise to ground.
Installation Requirements
Route the cable away from high-voltage power lines to minimize EMI exposure. Secure the cable with appropriate clamps at regular intervals, ensuring the minimum bend radius is strictly observed. Connect the shield drain wire to the cabinet’s grounding busbar.
Usage Precautions
- Always verify the pinout diagram against the field device wiring before applying power.
- Inspect the cable jacket for any cuts or abrasions before installation.
- Never pull the cable by the wires themselves; always handle by the connector body.
