Product BulletinD104791X012May 2024 Fisher™ FIELDVUE™ DVC7K-HDigital Valve Controller for On/Off ApplicationsDVC7K-H Digital Valve Controller for On/Off Applications Product Bulletin May 2024 D104791X012The FIELDVUE DVC7K digital valve controller is reliableand intuitive, featuring diagnostics that are targeted foryour On/Off applications. It converts a 4-20 mA or 24 V DCinput signal into a pneumatic output signal that controlsthe actuator on the valve. Perform setup and configurationprocedures, check the valve health, and get Advice at theDevice™ using the simple-to-use Local User Interface(LUI). The interface can be configured to support multiplelanguages with a few button pushes.FeaturesReliabilityLinkage‐Less Non‐Contact Position Feedback — Thehigh performance, linkage-less feedback system, shownin Figure 1, eliminates physical contact between the valvestem and the instrument. There is no wearing of partsso cycle life is maximized. Additionally, the eliminationof levers and linkages reduces the number of mounting parts and mounting complexity. Instrument replacement and maintenance is simplified because the feedback parts stay connected to the actuator stem.Built to Survive — The DVC7K's field-proven conformal coated electronics resist the effects of vibration, temperature and corrosive atmospheres per the ISA.75.13 standard. A weather‐tight housing construction protects the wiring terminal box and critical components from harsh environmental conditions.Eliminate Solenoids — DVC7Ks in the On/Off Application Mode provide a more reliable solution over traditional solenoid valves. They also provide diagnostic alerts to support early identification of problemsPerformanceAccurate and Responsive — The two‐stage instrument design provides quick response. Additionally, the DVC7K allows users to customize the performance of their valve, with a configurable ramp open rate and ramp closed rate.Stroke Time Analysis available for On/Off applications Ease of UseEnhanced Safety — The DVC7K is a HART®communicating device; information can be accessed anywhere along the loop. This flexibility can reduce exposure to hazardous environments and make it easierto evaluate valves in hard-to-reach locations.Local User Interface (LUI) — The full text display inthe local interface is easy to navigate due to the six button LUI (Figure 2). Each unit can be configured to display Arabic, Chinese, Czech, English, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian or Spanish. View the Travel vs. Travel Setpoint, Instrument Mode and Valve Health instantly from the home screen.Valve Health — Identify the health status of the valve assembly at a distance with the NE 107 LED indicator. Quickly troubleshoot issues and identify recommended actions with Advice at the Device. Additionally, use theLUI to view primary variables like supply pressure and input current.Faster Commissioning — HART communications allow the user to quickly commission loops with a varietyof tools from a remote location or locally at the valve assembly with the LUI.Figure 1.Linkage-Less Non-Contact Feedback SystemROTARY MAGNET ARRAY12Product BulletinDVC7K-H Digital Valve Controller for On/Off ApplicationsD104791X012May 2024Flexible Connectivity — Emerson's secure Bluetooth ®wireless technology implementation (future release) enables ability to see health across multiple valves.Easy Maintenance — The DVC7K is modular in design.Critical working components can be replaced without removing field wiring or pneumatic tubing.ValueHardware Savings — When installed in an integratedcontrol system, significant hardware and installation cost savings can be achieved. Valve accessories such as limit switches and position transmitters can be eliminated due to the integrated position transmitter and switch option. Solenoid valves can also be eliminated with the On/Off application mode capabilitiesIncreased Uptime — The self‐diagnostic capabilityof the DVC7K provides valve performance and health evaluation without shutting down the process or pulling the valve assembly from the line.Improved Maintenance Decisions — Digitalcommunication provides easy access to the condition of the valve. Sound decisions can be made by analysis of valve information through any HART communicating asset management software.Figure 2. Local User InterfaceValve DiagnosticsWith the DVC7K digital valve controller's enhanced memory, it is able to provide a comprehensive library of valvediagnostic alerts, as shown in Figure 3. These diagnostics and recommended actions are easily accessed with an Emerson handheld communicator or from the LUI. When installed as part of a HART communicating system, the DVC7K delivers prompt notification of current or potential equipment issues directly to the asset management system and supports NAMUR NE107 alert categorization.Alerts assist in identification and notification of the following situations:Stroke open and/or stroke close degradationValve travel deviation identifies stuck valves that don'tmake full travelCycle count / Travel AccumulatorVarious instrument mechanical and electrical issuesLeverage an Emerson handheld communicator to view the instrument Event Log which stores alerts in memory on board the DVC7K, view graphical data, and quickly identifythe stroke open and stroke close times.3DVC7K-H Digital Valve Controller for On/Off ApplicationsProduct BulletinMay 2024D104791X012Figure 3.Remote Interface Examples [via DD (Device Description) and FDI (Field Device Integration) Package]ACTIVE ALERTSProduct Bulletin DVC7K-H Digital Valve Controller for On/Off Applications D104791X012 May 2024- continued -4DVC7K-H Digital Valve Controller for On/Off Applications Product Bulletin May 2024 D104791X0125Product Bulletin DVC7K-H Digital Valve Controller for On/Off Applications D104791X012 May 2024- continued -6DVC7K-H Digital Valve Controller for On/Off Applications Product Bulletin May 2024 D104791X012- continued -7Product Bulletin DVC7K-H Digital Valve Controller for On/Off Applications D104791X012 May 20248DVC7K-H Digital Valve Controller for On/Off Applications Product Bulletin May 2024 D104791X012910Product BulletinDVC7K-H Digital Valve Controller for On/Off ApplicationsD104791X012May 2024Typical model number:D104791X012 © 2024 Fisher Controls International LLC.
