Emerson DVC2000 Digital Valve Controller
FIELDVUE® DVC2000 Series digital valve controllers are HART® communicating, microprocessor-based current-to-pneumatic instruments. Utilizing technologies and experience learned from the DVC6000 product line, new features and capabilities have been added to address additional application needs including:
- Linkage-less, non-contact valve position feedback system
- Local user interface including an LCD and pushbuttons for navigation
- 7-language support
- Automatic tuning
- 2 Integrated limit switches (1 mA or 4 mA output for open or closed indication)
- Integrated valve position transmitter (4-20mA output)
- NAMUR mounting
- Compact size for small valves and tight spaces
These features and capabilities were developed to support a global customer base that requires a simple, easy to use, digital valve controller. Most striking is the patented non-contact, linkage-free valve position feedback system. With no touching parts, the feedback system capitalizes on magnetic technology while improving instrument reliability on linear or rotary valves. Configuration of the DVC2000 is simple with the full text, multilingual local user interface. English, German, Italian, Spanish, French, Chinese and Japanese languages are supported in every device.
Truly capitalizing on the power of digital technology, the DVC2000 also supports the FIELDVUE instrument’s unique Performance Diagnostics capability. While the control valve is operating, critical valve performance information is available to evaluate and make decisions regarding the health of the entire control valve assembly. Information is communicated to the appropriate personnel via a red-yellow-green snapshot and is further supported with recommendations on how to correct any problems identified.
