METSO A413345 Power Supply / Filter / Distribution Board
the METSO A413345 is a specialized module belonging to the Valmet / Metso DNA (formerly Damatic) automation family.
This specific part is generally identified as a Power Supply and Distribution Module or a Power Filter Unit used to provide stable, filtered energy to the processing boards within the system rack.
1. Product Description
The METSO A413345 is a high-reliability power management card. In a Distributed Control System (DCS), sensitive processor boards (like the A413665) require clean, surge-protected power to prevent data corruption or hardware failure.
The A413345 filters the incoming cabinet power (typically 24V DC) and distributes it across the backplane to various I/O and control modules.
Manufacturer: Valmet / Metso Automation
Component Type: Power Supply / Filter / Distribution Board
System Compatibility: Metso DNA / Damatic XDi
Installation: Slot-mounted in a standard Metso system sub-rack.

4. Application Cases
Refining & Chemicals: Ensuring the DCS remains powered during minor voltage fluctuations to prevent hazardous unplanned shutdowns.
Pulp & Paper: Providing stable power to the logic controllers governing massive paper machines where electrical noise from large motors is prevalent.
Power Plants: Used in turbine control systems where power reliability is a regulatory requirement.
Mining: Protecting control electronics from the “dirty” power often found in remote sites using generator sets or long-distance power lines.
5. Product Features and Advantages
Electrical Noise Suppression: Features advanced filtering circuitry to remove electromagnetic interference (EMI) that can disrupt digital signals.
Hot-Swap Support: In many rack configurations, the power system is designed to allow module replacement without interrupting the process (Redundancy).
Industrial Grade: Built to withstand high-ambient temperatures in sealed control cabinets.
Diagnostic Feedback: The integrated LEDs provide instant visual confirmation of power health, reducing troubleshooting time.
Galvanic Isolation: Helps isolate the sensitive control logic from external electrical faults.
