The Fisher Fieldvue DVC6000 series digital valve controller is a communicating, microprocessor-based current-to-pneumatic instrument. Describing the DVC6000 as a 'positioner' (an industry accepted term) ignores the power of digital technology. Digital valve controllers do more than position valves. The controllers can be used on single- or double-acting actuators. The digital valve controller receives feedback of the valve travel position plus supply and actuator pneumatic pressure. This allows the instrument to diagnose not only itself, but also the valve and actuator to which it is mounted. This provides users with cost effective maintenance information, so that required maintenance can be performed on the instrument and valve when there really is a need.
The DVC6000 digital valve controller from Fisher
Three important functions are performed by the DVC6000 Series instrument:
* Traditional positioning of a control valve by converting the 4-20 mA d.c. input signal from the process controller to a pneumatic output signal to the actuator.
* Automatic calibration and configuration utilising 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 advantages realised with Fieldvue instruments include:
* Improved control - two-way digital communications gives users current valve conditions. This realtime information enables users to make sound process management decisions.
* Enhanced safety - users can check instrument and valve operation and keep the process running smoothly and safely from a remote location. Personnel exposure to hazardous environments is minimised and hard-to-reach valve locations need to be accessed less frequently.
* Environmental protection - additional field wiring can be avoided by connecting a leak detector or limit switch to the auxiliary terminals in the Fieldvue digital valve controller. In this way, the instrument will issue an alert if limits are exceeded.
* Built to survive - the valve controllers are field-tough with fully encapsulated printed wiring boards that resist the effects of vibration, temperature and corrosive atmospheres. A separate weather-tight field wiring terminal box isolates field-wiring connections from other areas of the instrument.
* Increased uptime - with the self-diagnostic capability of the valve controller, users can answer questions about a valve's performance, without pulling the valve from the line.
* Faster commissioning - the two-way communication capability allows you to quickly commission loops by remotely identifying each instrument, verifying its calibration, reviewing stored maintenance notes, and more.
Designed for ruggedness and easy maintenance, the DVC6000 Series 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.
