■Open solution
・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
■Fieldbus networks
・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
■Mounting on actuators and valves
・Can be mounted on single and double-acting actuators
・Both rotary and linear valves

parameters
■Technical Description
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.
■Self-diagnostics
Advanced self-diagnostics guarantees that all measurements operate correctly.
