METSO A413222 I/O Interface / Channel Board

The METSO A413222 is a specialized electronic module within the Valmet / Metso DNA (Distributed Control System) hardware family. 

It is primarily identified as an I/O Interface Card or Channel Board, often used for specific signal processing tasks between field devices and the system controllers.

1. Product Description

The METSO A413222 is a modular circuit board designed for industrial automation.

 Its primary role is to act as an interface for field signals (such as sensors or actuators), converting and conditioning these signals for use by the central processing units (like the A413654 or A413665). 

It is built for high-density environments where space and reliability are critical.

Manufacturer: Valmet / Metso Automation

System Family: Metso DNA / Damatic XDi

3. Related Models

The A413222 is part of a broader ecosystem and is typically used alongside:

A413110 (TIU6): Terminal Interface Unit for wiring connections.

A413665 (ACU): The Active Control Unit that processes the logic for this board.

D100532: The Bus Connection Module that facilitates data transfer to the backplane.

A413220 / A413221: Variants of the interface card with different channel densities or signal types.

4. Application Cases

Chemical Processing: Monitoring flow meters and pressure transmitters in volatile environments where electrical isolation is required.

Mining & Metal: Handling the digital and analog feedback from heavy-duty motors and conveyor systems in Lokotrack® or stationary plants.

Power Plants: Managing the I/O for auxiliary systems such as cooling water or lubrication loops.

Pulp & Paper: Integration into Valmet DNA systems for paper machine drying and pressing sections.

5. Product Features and Advantages

High Signal Accuracy: Precision components ensure that the conversion between analog field signals and digital system data is highly accurate.

Rugged Construction: Designed to operate in high-temperature and high-vibration industrial cabinets.

Advanced Self-Diagnostics: The board can detect internal faults or line breaks, reporting them immediately to the operator to reduce MTTR (Mean Time To Repair).

Galvanic Protection: Protects the expensive central processor from electrical spikes or grounding issues originating in the field.

Density: Multi-channel design allows for more I/O points in a smaller cabinet footprint.
