Description
Foxboro P0800DC
Technical Specifications
- Product Type: Cable Isolator.
- System Compatibility: Foxboro I/A Series Fieldbus Network.
- Isolation: High-voltage galvanic isolation between field and system sides.
Functional Features
- Signal Protection: Effectively cuts ground loops and prevents field-side surges from damaging the control system.
- Signal Regeneration: Enhances signal integrity over long cable runs by reshaping and amplifying the signal.
- Fault Containment: Isolates short circuits or faults on the field side to prevent them from bringing down the entire network segment.
Application Scenarios
Used in industrial environments with high electromagnetic noise, long cable runs, or significant ground potential differences between field devices and the control room.
Performance Parameters
- Isolation Voltage: High dielectric strength to ensure safety and signal purity.
- Transmission Delay: Minimal latency to maintain real-time control performance.
Material Composition
Industrial-grade internal components with high-quality insulation materials. Enclosed in a protective housing suitable for panel mounting.
Structural Characteristics
Compact form factor designed for DIN rail or panel mounting. Features clearly labeled input/output terminals and status LEDs.
Working Principle
Utilizes optical or magnetic isolation technology to transmit data across an isolation barrier without a direct electrical connection, thereby breaking ground loops while maintaining signal fidelity.
Installation Requirements
Install as close to the field entry point as possible. Ensure the isolation ground is connected to a clean earth reference.
Usage Precautions
- Do not bridge the isolation barrier with external wiring.
- Verify the isolation rating matches the potential difference in the application.
- Replace immediately if physical damage to the enclosure is observed.
