Metso D201291 | ACN SR1 Small Rail-Mounted Controller

Description

Core Product Summary (Brand / Model / Key Attributes)

The Metso D201291 is an ACN SR1 small rail-mounted controller used within the Metso DNA automation platform. It provides compact process control capability for applications that require a space-efficient controller node mounted on a DIN rail or similar rail system.

The module is designed for field or cabinet installation and supports the control, I/O, and communication functions of the ACN SR1 series within the DNA distributed control architecture.

Key Technical Specifications

Detailed Product Overview

The Metso D201291 belongs to the ACN SR1 family of compact controllers in the Metso DNA automation system. ACN SR1 nodes are designed for installations where a full rack-mounted controller is not required, offering a smaller footprint suitable for distributed or local control tasks.

The D201291 functions as a process control node capable of executing control logic, handling associated I/O, and communicating within the DNA network. It is typically mounted on a standard industrial rail and integrates with other DNA system components such as I/O modules, operator interfaces, and higher-level engineering tools.

Because it is a system-specific controller, configuration and application programming are performed using Metso DNA engineering software. Power, communication, and I/O connections follow the standards defined for the ACN SR1 series. Correct identification of the exact node type and system revision is required before replacement or expansion.

The module is intended for continuous industrial operation and forms part of the scalable control hierarchy of the DNA platform, ranging from small local nodes to larger plant-wide systems.
