Functional Features:

• High-resolution and high-precision signal output ensuring accuracy and stability

• Channel-to-channel or system electrical isolation enhancing reliability and preventing ground loop issues

• Seamless integration into Metso/Valmet automation control system architectures

• Industrial-grade design for reliable operation in harsh environments with temperature variations, vibration, and electrical noise

• Multiple output channels for simultaneous control of multiple analog actuators

Performance Parameters:

• Converts digital control values to 4-20 mA current signals or 0-10 V voltage signals

• Precision control of valves, variable frequency drives, and analog instruments

• Supports standard industrial current outputs (4-20 mA or 0-20 mA) and voltage outputs (0-10 V)

Material Composition: Aluminum alloy housing with stainless steel internal components and corrosion-resistant coating

Structural Characteristics: Modular I/O form factor designed for rack or backplane mounting within Metso/Valmet control system architecture

Working Principle: The module receives digital command signals from the control system processor and converts them into continuous analog signals. These analog signals drive field actuators such as control valves, variable frequency drives, analog instruments, or variable speed pumps, achieving precise regulation of process variables like flow, pressure, and temperature.

Advantages and Strengths:

• Enables precise closed-loop control of complex process variables

• Ensures efficient and stable production process operation

• SIL 2/SIL 3 certified as part of system

• Compatible with SVI II AP, Series 2000, and early ND9000 positioner bodies

Applicable Industries:

• Pulp and paper

• Power generation and energy

• Mineral processing and mining

• Process industries requiring precision analog output control

Model Series: Valmet/Neles Series 2000 / SVI II AP / ND9000 Smart Positioner Series

Installation Requirements: Module installed in Metso/Valmet control system rack or backplane

Usage Precautions:

• Detailed technical data available in official Metso/Valmet manuals

• Confirm compatibility with specific positioner or control system revision
