Description
Product Introduction & Engineering Value
The A413015 belongs to an older generation of Valmet/Metso Automation control hardware, where individual circuit boards were maintained as replaceable plant-floor components. Its identification as an NCU board makes revision and system compatibility particularly important when sourcing a replacement.
This is not a part where a generic “same-looking PCB” is an adequate substitute. A413015 references appear with different revision numbers, including Ver.05, so the revision printed on the installed board should be recorded before procurement.
Technical Specifications
| Parameter | Specification / Identification |
|---|---|
| Part Number | A413015 |
| Manufacturer | Metso Automation / Valmet |
| Board Designation | NCU |
| Hardware Type | PC board / circuit board |
| Application | Valmet/Metso industrial automation systems |
| Board Revision | Revision-dependent; Ver.05 is documented in secondary listings |
| Product Status | Discontinued according to current aftermarket references |
| Installation | System/rack-mounted industrial control board |
| Part Category | Automation control PCB |
| Replacement Consideration | Exact revision and installed system configuration should be matched |
Important: Publicly available documentation for this legacy part is limited. I would not treat unverified marketplace specifications—such as voltage, processor type, memory capacity, or connector pinout—as authoritative. The available evidence confirms the A413015 identity and NCU/PCB classification, but does not provide a reliable OEM electrical specification sheet.
Field Application & the “Trench” Experience
Picture a legacy Valmet automation cabinet that has been operating for years. The control system itself is still serviceable, but one NCU board begins producing intermittent faults during startup. The plant does not necessarily need a complete control-system migration; the immediate requirement is an accurately matched replacement board.
This is where the A413015 revision becomes important. A field listing specifically identifies an A413015 Ver.05 NCU circuit board, while other listings simply use the base A413015 number. For an installed system, the correct procurement process is therefore to photograph the board label, record the revision, and compare the connector and board layout before shipment.
Specific application scenarios
- Legacy Valmet process-control cabinets where the original NCU architecture remains in production.
- Paper and pulp automation systems using older Valmet control hardware.
- Plant-floor control-system maintenance where replacing an individual PCB is preferable to disturbing a larger installed control architecture.
- Obsolete-system spare stocking, where one verified A413015 is retained as a contingency replacement.

Transparency SOP: QA & Testing
For New Surplus or refurbished A413015 inventory, the inspection should concentrate on board identity and physical/electrical condition.
- Part-number verification — confirm the PCB is marked A413015.
- Revision verification — record the revision number, such as Ver.05 where applicable.
- PCB inspection — check the board for corrosion, damaged components, lifted traces, cracked solder joints, and connector damage.
- Storage-condition inspection — look for evidence of moisture exposure, contamination, or prolonged improper storage.
- Functional testing — where the appropriate Valmet/Metso test environment is available, verify operation in the corresponding system rather than relying solely on a visual inspection.
- Documentation — provide available photographs, identification information, and test records with the supplied unit.
Current aftermarket references identify A413015 as discontinued, which makes condition and revision verification especially important when purchasing surplus inventory.
The Veteran’s Tech Trap Guide
⚠️ Do not order from the base part number alone.
If the installed board says A413015 Ver.05, document that revision. Legacy Metso/Valmet boards can have revision-specific hardware or firmware characteristics, and a seller listing that only says “A413015” does not establish revision equivalence.
⚠️ Do not confuse A413015 with nearby A413xxx boards.
The same product family contains boards such as A413016, A413043, A413044, A413077, A413082, A413111, A413125, and A413135, but their functions are different. The A413015 should be identified by its complete part number and board marking.
PRO TIP: For a legacy control cabinet, photograph both the component side and the identification label before requesting a replacement. If the supplier cannot confirm the board revision, connector arrangement, and physical match, the procurement risk is higher than the base part number suggests.
⚠️ Be careful with third-party technical claims.
Some current marketplace pages attach detailed electrical specifications to A413015 without providing an OEM document to support them. Those figures should not be used for engineering substitution without verification.
Dynamic FAQ
1. What is the Metso A413015?
The A413015 is identified as a Metso Automation / Valmet NCU circuit board or PC board used in legacy industrial automation equipment.
2. Is A413015 still manufactured?
Current aftermarket references list the A413015 as discontinued by the manufacturer. As a result, sourcing commonly involves surplus, unused-stock, or refurbished inventory.
3. Are different A413015 revisions available?
Yes. Secondary industrial-parts listings document versions including A413015 Ver.05. The revision should be checked against the installed board before ordering.
4. Is A413015 a CPU?
Available references identify it as an NCU board, not simply a generic CPU module. Other nearby Valmet part numbers, such as A413044 and A413082, are separately identified as CPU boards. Therefore, the exact function should not be inferred from the A413015 part number alone.
5. Can a refurbished A413015 be used as a replacement?
Potentially, provided the board revision, physical configuration, system compatibility, and functional test results match the installed application. For a legacy controller, testing in the appropriate system environment is preferable to a basic power-on test.
6. What should be confirmed when buying New Surplus A413015?
Ask for the exact part number, revision, photographs of the PCB and label, physical condition, available test report, and warranty terms. “New Surplus” describes inventory condition; it should not by itself be treated as proof of current OEM production status.
7. What warranty is available?
Warranty depends on the supplier and stock condition. For a discontinued A413015, obtain the warranty period and coverage in writing, particularly for refurbished inventory.
