Metso A413600 PLC Rack Fan Assembly

Description

Product Introduction & Engineering Value

The Metso A413600 is a cooling assembly rather than a control or I/O module. Its job is straightforward: maintain forced airflow around the electronics installed in a legacy Metso/Valmet PLC rack or cabinet. Available part-specific documentation identifies three 24 VDC brushless fans in the assembly.

For maintenance teams supporting older automation installations, the fan assembly matters because degraded airflow can turn a marginal cabinet-temperature condition into an electronics reliability problem. Fan replacement should therefore include an airflow and temperature check, not just a visual confirmation that the blades rotate.

Technical Specifications

Radwell reports a 1.10 kg weight and identifies the unit as a cabinet fan with three 24 VDC brushless fans. The older River City Industrial listing associates A413600 with a PLC module rack and gives approximate dimensions of 17 × 9 × 5.5 inches. Those dimensions are from an aftermarket inventory listing, not an OEM mechanical drawing, so they should not be used as controlled installation dimensions.

Identification note

There is conflicting secondary-market information for A413600. One 2025 conformity-document extract associates the same part number with a Metso DI8P digital input module, while multiple independent industrial-part records identify A413600 as the three-fan cabinet assembly.

For procurement, the physical assembly, label, connector arrangement, and installed cabinet position should therefore be checked against the customer’s existing A413600. Do not rely on a generic marketplace title alone.

Field Application & Practical Maintenance Scenario

A typical maintenance situation involves an older Valmet PLC cabinet where the control system itself is still operating correctly, but the rack cooling assembly has developed noisy or intermittent fans.

An engineer may initially see only a temperature increase during extended operation. The actual problem can be mechanical: a fan bearing begins to deteriorate, airflow falls, and the remaining fans carry a greater thermal burden.

Practical applications

• Valmet/Metso PLC module racks requiring dedicated forced-air cooling.
• Legacy pulp-and-paper automation cabinets where the original rack cooling hardware remains in service.
• Process-control cabinets where cabinet temperature must remain within the installed electronics’ operating limits.
• Maintenance spare inventories for older automation systems where an exact fan assembly is preferable to field-modifying the cabinet.

The important point is that A413600 is a cooling assembly, not a PLC processor or signal module. Current industrial listings consistently place it in the fan/ventilation category.

QA & Testing SOP

For a New Surplus or refurbished A413600, a practical inspection sequence is:

1. Part identification
Verify the A413600 marking, manufacturer label, revision information if present, and physical configuration.

2. Fan-count verification
Confirm that the assembly contains the expected three fan positions and that the actual hardware matches the supplied photographs.

3. Mechanical inspection
Check mounting hardware, fan guards, brackets, wiring, connectors, and the fan housings for damage or corrosion.

4. Individual fan test
Energize each fan using the appropriate controlled 24 VDC test source. Check startup behavior, abnormal vibration, bearing noise, and intermittent stopping.

5. Current and operating check
Where the correct test fixture is available, monitor fan current and operating stability rather than relying only on whether the blades turn.

6. Airflow verification
Confirm that all three fans produce useful airflow in the intended direction.

7. Cabinet-level test
After installation, verify rack airflow and cabinet temperature under normal operating load.

8. Documentation
Record the supplied part number, condition, visible revision markings, test results, and photographs before shipment.

New Surplus authenticity

A New Surplus A413600 should be unused original inventory, not a newly manufactured generic fan assembly. Radwell distinguishes between unused original packaging, unused repackaged stock, and refurbished units, which is a useful distinction when comparing inventory descriptions.

Veteran’s Tech Trap Guide

⚠️ Trap 1: Treating A413600 as an electronic control card

Some online listings describe A413600 generically as an automation control module. A current conformity-document record even associates the number with a DI8P digital-input module. However, several independent part-specific records identify A413600 as a cabinet fan unit with three 24 VDC brushless fans.

PRO TIP: If the supplier cannot provide a clear photograph of the actual A413600 assembly, do not rely on the product title alone.

⚠️ Trap 2: Replacing one failed fan without checking the assembly

A single noisy fan does not necessarily mean the entire assembly is electrically defective. Check all three fans, wiring, airflow direction, and cabinet temperature before deciding on the replacement scope.

PRO TIP: Test all three fan positions before returning the cabinet to continuous operation.

⚠️ Trap 3: Treating aftermarket dimensions as OEM dimensions

The 17 × 9 × 5.5 inch dimensions found in a historical listing are useful for inventory identification but are not an OEM mechanical drawing.

Do not fabricate mounting modifications from those dimensions. Compare the actual replacement assembly with the installed unit before installation.

⚠️ Trap 4: Confusing fan voltage with cabinet supply voltage

The available documentation identifies the individual fans as 24 VDC. That does not by itself establish the complete cabinet’s incoming power specification.

Verify the cabinet wiring diagram and the original assembly’s connection points before applying power.

Dynamic FAQ

Q1. What is the Metso A413600?

A413600 is identified by multiple industrial-part sources as a Metso Automation / Valmet cabinet fan unit containing three 24 VDC brushless fans. It is used for cooling PLC rack or automation-cabinet hardware.

Q2. Is A413600 a PLC I/O module?

The stronger part-specific evidence identifies A413600 as a fan/ventilation assembly, not a CPU, analog I/O, or digital I/O card. However, one 2025 conformity-document extract associates the same number with a DI8P digital-input module, so the actual part label and physical configuration should be verified before purchase.

Q3. How many fans does A413600 contain?

The available product records identify three 24 VDC brushless fans.

Q4. Is Metso A413600 discontinued?

Yes. Radwell identifies A413600 as discontinued by the manufacturer. Remaining inventory is therefore commonly offered as unused surplus, never-used stock, used equipment, or refurbished hardware.

Q5. Can I replace A413600 with individual 24 V fans?

Electrically, a 24 VDC fan may appear similar, but that does not establish mechanical or system compatibility. The original assembly’s airflow direction, dimensions, mounting, connector, current characteristics, and fan spacing should be checked before substituting individual fans.

Q6. How do I verify New Surplus A413600 authenticity?

Request photographs of the actual assembly, including the Metso/Valmet identification label, fan arrangement, connectors, wiring, and mounting structure. Confirm that the supplied hardware matches the installed assembly rather than relying solely on an online product description.

Q7. What warranty should I expect?

Warranty depends on the supplier and stock condition. For example, Radwell currently states that its own two-year warranty applies to its A413600 inventory, while another historical supplier listing offered a 30-day warranty on used units. Always confirm the warranty applicable to the exact condition being purchased.
