□ Low power comsumption enables installation to all

common control systems

Open solution

□ Metso is committed to delivering products that freely

interface with software and hardware from a variety of

manufacturers; ND9000 is no exception. This open

architecture allows the ND9000 to be integrated with

other field devices to give an unprecedented level of

controllability.

Neles ND9000 in fieldbus networks

□ Approved interoperability

□ Host interoperability ensured

□ FOUNDATION fieldbus ITK version 6.1.2 certified

□ Profibus PA profile version 3.0 PNO certified

□ 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 enviroment

□ 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 onoff 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

TECHNICAL DESCRIPTION

The ND9000 is a 4–20 mA or fieldbus powered microcontrollerbased intelligent valve controller. The device contains a Local

User Interface (LUI) enabling local configuration. A PC with FieldCare software can be connected to the ND9000 itself or to the

control loop. 

The powerful 32-bit microcontroller controls the valve position.
