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.

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:
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.
Truly capitalizing on the power of digital technology, the DVC2000 also supports the unique Performance Diagnostics (PD) capability of FIELDVUE instruments. 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 identified problems.
|FIELDVUE™ DVC6200||Instruction Manual||Product Bulletin|
|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:
This instrument provides one platform for any pneumatic actuator application. The DVC6200 can be installed on sliding-stem, rotary, single- or double-acting actuators.
Designed for ruggedness and easy maintenance, the DVC6200 is modular. The single master module can be removed from the instrument housing without disconnecting the field wiring, pneumatic connections, or stem linkages. This master module contains the critical sub-modules so component removal is quick and simple.
|FIELDVUE™ DVCSIS||Instruction Manual||Product Bulletin|
The operation of many industrial processes involves inherent risk. Instrumented protection systems are specifically designed to reduce the severity of the impact of an emergency event. These systems, such as Safety Instrumented Systems (SIS), are designed to monitor a process for potentially dangerous conditions. During an emergency event, the SIS instrument activates the valve to move the process to a safe state.
What happens if the valve does not move when an emergency event occurs? Personnel safety, equipment damage, and environmental protection could be at serious risk.
Traditionally, a pneumatic test panel located near the valve provides a means to exercise the valve to ensure operation when called upon. However, the procedures to test the valves are labor-intensive, cumbersome, and may require the valve to be locked in a fixed position or bypassed.
FIELDVUE™ digital valve controllers installed on emergency shutdown valves offer state-of-the-art testing methods. Using HART® communication, the 375 Field Communicator or ValveLink™ Software replace the function of the pneumatic test panel to verify operation of the emergency shutdown valve. The results are improved system performance and valve diagnostic capability along with a reduction in testing time and initial investment cost.
Automatic testing – A scheduling and batch running tool within ValveLink Software can be used to automate multiple diagnostic tests.
|Smart Wireless 775 THUM Adapter||Product Bulletin|
|The Smart Wireless THUM adapter allows you to wirelessly gain the full benefits of FIELDVUE instruments by unlocking stranded diagnostic information. 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.|
