Description
Woodward 8200-508
Technical Specifications
- Part Number: 8200-508
- Communication: HART or Modbus RTU protocol
- Power Supply: 24 VDC
- Input Signal: 4-20 mA with HART overlay
Functional Features
- Digital Communication: Supports HART protocol for remote configuration, calibration, and diagnostics.
- Advanced Diagnostics: Records valve travel history, cycle count, and friction trends for predictive maintenance.
- Fail-Safe Operation: Configurable fail-open, fail-close, or fail-in-place modes upon signal loss.
Application Scenarios
Ideal for critical process valves in power generation, petrochemical refining, and pipeline compression where predictive maintenance is essential.
Performance Parameters
- Resolution: 12-bit or better position resolution.
- Repeatability: ±0.05% of span.
Material Composition
Corrosion-resistant enclosure with premium pneumatic seals rated for extended service life.
Structural Characteristics
- Mounting: NAMUR-compliant direct mount or bracket mount.
- Display: Optional local LCD display for real-time parameter viewing.
Working Principle
Combines traditional pneumatic positioning with digital intelligence. The microprocessor processes both the analog command and digital HART signals, executing advanced control algorithms while communicating diagnostic data back to the host system.
Installation Requirements
- Wiring: Use shielded twisted-pair cable for HART communication.
- Grounding: Ensure proper grounding to prevent communication interference.
Usage Precautions
- HART Compatibility: Verify HART version compatibility with the host DCS.
- Configuration: Save configuration parameters to a backup file after commissioning.
