to all common control systems
?Interchangeable communication options:
HART 6 or 7 (H)
FOUNDATION fieldbus
Profibus PA
?Limit switches
?Position transmitter (in HART only)
?Full stainless steel enclosure
?Exhaust adapter
?Remote mounting
?Arctic temperature specifications: (Up to –53°C)
?The ND9000 can be freely interfaced with software and hardware from a variety of
manufacturers. Using this open architecture allows the ND9000 to be integrated with other field
devices to give higher controllability.
?FDT and EDD based multi-vendor support configuration
?Support files for ND9000 are available at the following website: www.neles.com/valves
?Interoperability
Host interoperability
FOUNDATION fieldbus ITK version 6.1.2
Profibus PA profile version 3.0 PNO
?Easy to upgrade; by replacing the HART communication board with a fieldbus communication
board
?Excellent maintainability with firmware download feature
?Advanced communication diagnostics
?Digital communication via the fieldbus includes not only the set point, but also the position
feedback signal. from the position sensor. No special supplementary modules for analog or
digital position feedback are needed when using the fieldbus valve controller.
?Back up LAS functionality available in FOUNDATION fieldbus environment
?Input selector and output splitter blocks available in FOUNDATION fieldbus devices allowing
advanced distributed control
?Standard function blocks enables the freedom to use the ND9000 intelligent valve controller in
either continuous or on-off control applications
?Open and close information is directly available via the fieldbus
?Open and close detection is based on either position measurement (soft limit switch) or
mechanical limit switch information
?Can be mounted on single and double-acting actuators
?Both rotary and linear valves
?Ability to attach options to electronics and mechanics later
?1-point calibration feature enables mounting without disturbing the process

?Wear resistant and sealed components
?Contactless position measurement
?Easy access to collected data with Metso
Device Care software
?Unique Online Valve Signature to detect valve
friction even more accurately.
?Performance view with report, which gives
guidelines for recommended actions.
?Logical trend and histogram collection
?Information collected during process uptime
?Extensive set of off-line tests with accurate
key figure calculations
?Fast notifications with on-line alarms
?Condition monitoring tool available
?Real time monitoring of valve control
parameters
The ND9000 is a 4–20 mA or fieldbus powered microcontroller-
based intelligent valve controller.
The device contains a Local User Interface (LUI) enabling
local configuration.
A PC with Device Care software can be connected to the ND9000 itself or to the control loop.
Advanced self-diagnostics guarantees that all measurements operate correctly.
