FIELDVUE™ DVC6200f digital valve controllers are communicating, microprocessor-based current-to-pneumatic instruments with linkage-less, non-contact travel feedback. Three important functions are performed by the DVC6200f instrument:
Controlling the movement of a valve stem or shaft by converting the digital input signal from the process controller to a pneumatic output signal to the actuator.
Automatic calibration and configuration using the power of microprocessor technology.
Communication capability via the FOUNDATION™ fieldbus protocol to provide instrument and valve diagnostic information..Registered by the Fieldbus Foundation, the DVC6200f uses the patented linkage-less, non-contact travel feedback technology. It offers an all digital Foundation fliedbus open communication protocol..
When installed in an Emerson Process Management PlantWeb™ system, the instrument will continually run valve diagnostics on-board. If and when problems are detected, the information can be directed to the appropriate personnel, automatically.
FIELDVUE™ DVC6200 and DVC2000 digital valve controllers are HART® communication instruments approved for non-incendive, intrinsic safety, flameproof and explosion proof applications. Digital valve controllers work on single- or double-acting actuators. FIELDVUE digital valve controllers provide online valve diagnostics and are a core part of the Emerson PlantWeb™ digital plant architecture.
The Smart Wireless THUM adapter is a device for use on HART® communicating instruments such as the Fisher FIELDVUE™ digital valve controller. The THUM adapter adapts the wired HART protocol to the Wireless HART protocol. The Smart Wireless THUM™ adapter is an easy way to unleash otherwise “stranded” valve diagnostics. This reduces unplanned shutdowns by using existing diagnostics available within your current control system. FIELDVUE digital valve controllers coupled with the Smart Wireless THUM adapter power the PlantWeb™ digital plant architecture by delivering more advanced field intelligence for better decision-making to help you achieve unparalleled efficiency and productivity.
FIELDVUE™ DVC2000 digital valve controllers are HART® communicating, microprocessor-based current-to-pneumatic instruments. Using 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 a 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-less 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.
Fisher® FIELDVUE™ DVC6200 digital valve controllers are HART® communicating, microprocessor-based current-to-pneumatic instruments with linkage-less, non-contact travel feedback. Three important functions are performed by the DVC6200 instrument:
Traditional positioning of a control valve by converting the 4-20mA DC input signal from the process controller to a pneumatic output signal to the actuator. Automatic calibration and configuration utilizing the power of microprocessor technology. Communication capability via the HART communications protocol to provide instrument and valve diagnostic information..This instrument provides one platform for any pneumatic actuator application. The DVC6200 can be installed on sliding-stem, rotary, single- or double-acting actuators.
