3. Key Technical Specifications
| Parameter | Value |
|---|---|
| Product Type | Automation / Interface / Support Module |
| Compatible System | Metso Damatic XDi / Metso DNA DCS |
| Primary Function | System support, interfacing, or specialized processing within the rack (exact role revision-dependent) |
| Interface | Proprietary high-speed backplane |
| Power | Supplied via rack backplane (typical 24 V DC derived rails) |
| Form Factor | Plug-in printed circuit board for dedicated slot |
| Operating Temperature | Industrial range (typically −20 °C to +60 °C) |
| Mounting | Dedicated slot in compatible Metso/Valmet rack |
| Notes | Exact function, pinout, firmware, and revision details must be verified against the OEM datasheet and your existing system configuration before installation. |
4. Product Introduction
The Valmet A413792 is a printed circuit board module used in Metso Damatic XDi and related Metso DNA distributed control systems. It belongs to the A413xxx family of boards that perform processing, interfacing, communication, or system support functions inside Processing Unit and I/O racks.
These modules remain in service in pulp & paper, power generation, mining, and process plants still running legacy Damatic or early DNA architectures. When a board fails, a verified surplus unit of the correct revision is the practical way to restore the rack without a full system migration.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Module not recognized / no status | Seating issue, wrong revision, or hardware fault | High | Reseat board; confirm part number and revision | Match exact revision; replace if still unrecognized |
| Loss of related I/O or communication | Backplane or module failure | High | Check adjacent modules and backplane continuity | Isolate fault to this board before replacement |
| Intermittent operation | Poor contact, overheating, or marginal power | Medium | Inspect edge connector, temperature, and supply rails | Clean contacts; improve cooling; replace if unstable |
| System faults after installation | Revision or configuration mismatch | High | Compare labels with original failed unit | Use matching hardware revision |
| Physical damage indicators | Corrosion, bent pins, or prior rework | High | Visual inspection of board and connectors | Do not install damaged units |
| No change after swap | Upstream power or network issue | Medium | Verify rack power and network status first | Confirm external factors before condemning the board |
If diagnostics remain inconclusive, collect clear photos of the board labels, rack configuration, and any diagnostic messages before contacting support.
6. Frequently Asked Questions (FAQ)
Q: Is the Valmet A413792 still manufactured as new?
A: No. This is a legacy Damatic XDi / early DNA part. Available units are new surplus or carefully tested used boards. Stock is limited.
Q: Can I use any A4137xx board as a direct replacement?
A: Not reliably. Hardware and firmware revisions must be compatible with your existing system. Always record the full part number and revision from the failed board and match it as closely as possible.
Q: Do I need to reload configuration after swapping the module?
A: In many cases yes. Have a verified backup of the application or configuration ready and plan a controlled download with the appropriate Metso/Valmet engineering tool.
Q: What is the difference between New Surplus and Refurbished units?
A: New Surplus units are unused or factory-overstock boards that have never been installed. Refurbished units have been previously installed, cleaned, functionally tested on a compatible rack, and verified for proper operation. Both are tested before shipment.
Q: Is hot-swapping allowed?
A: No. Power the rack down completely before removing or inserting the module. Hot-swapping risks damage to the board or the backplane.
Q: How are these modules tested before shipment?
A: Visual inspection for corrosion or rework marks, power-on self-test on a compatible Damatic/Metso rack, communication/function verification, and basic operational checks. Test photos and a report are available on request.
Q: What should I confirm before ordering?
A: Exact part number and revision on the existing module, system type (Damatic XDi or DNA), and availability of a current configuration backup. Revision mismatch is the most common cause of post-installation problems.
