Description
Product Introduction & Engineering Value
The Metso A413792 is a legacy PEFT power-supply module, not an analog I/O or communications card. Its primary role is power conversion/distribution within the Metso/Valmet automation architecture. Multiple industrial inventories associate the exact part number with the PEFT designation and power-supply function.
For plants maintaining older Metso automation equipment, the important procurement detail is the complete hardware identity: A413792 + PEFT + model/revision information. Publicly available sources provide very limited OEM-level electrical specifications, so input voltage, output rails, current rating, and connector pinout should be verified against the installed module before replacement.

Specification caution
Several online pages attach unrelated specifications to A413792. One supplier describes it as a modern industrial control-interface module with analog inputs, digital outputs, Modbus TCP/IP, Profibus, and other specifications. That description conflicts with multiple independent listings identifying A413792 specifically as a PEFT power-supply module.
For that reason, specifications such as 24 VDC input, 4–20 mA channels, communication protocols, IP rating, temperature range, or output current should not be published as OEM specifications for A413792 without a primary Metso/Valmet document or the module’s nameplate confirming them.

Field Application & Practical Maintenance Scenario
A typical A413792 replacement situation occurs in a legacy Metso/Valmet control cabinet where the automation system remains operational but the original power module develops an output-voltage fault, thermal problem, or startup failure.
The maintenance team should first determine whether the fault is actually inside the PEFT module. A failed downstream load, damaged wiring, or cabinet-side power problem can produce symptoms that resemble a failed power supply.
Practical application scenarios
- Legacy Metso/Valmet PLC and process-control cabinets where PEFT power hardware remains in service.
- Pulp and paper automation systems maintained with original-generation Valmet electronics.
- Continuous-process control cabinets where an exact power-module spare is required to minimize restoration time.
- Obsolete-system maintenance programs where OEM replacement hardware is no longer readily available.
A413792 should therefore be treated as an exact-replacement power component, rather than a generic industrial 24 VDC supply.
QA & Testing SOP
For New Surplus or refurbished A413792 stock, use a controlled inspection sequence:
1. Identity check
Confirm:
- A413792 part number
- PEFT designation
- Model/revision marking
- Manufacturer label
- Serial or date information where present
2. Physical inspection
Inspect the enclosure, PCB, terminals, connectors, mounting hardware, labels, and insulation surfaces. Look for corrosion, impact damage, burned areas, cracked components, or evidence of previous repair.
3. Revision verification
A current inventory source specifically lists Model 07. Compare the complete identification marking against the customer’s installed unit before approving the replacement.
4. Pre-power electrical inspection
Check for obvious short circuits and abnormal resistance across the relevant power paths before energization. Do not apply production power to an unverified spare.
5. Controlled power-up
Use an appropriate laboratory or OEM-compatible test setup with current limiting. Monitor startup behavior and output stability rather than relying on a simple power-on indication.
6. Load testing
Where the correct test fixture and electrical documentation are available, test the module under a controlled representative load and monitor voltage stability, current behavior, and abnormal temperature rise.
7. System verification
After installation, verify the downstream Metso/Valmet equipment, power-good indications, and system startup sequence. Record measured values against the approved system documentation.
New Surplus authenticity
For New Surplus A413792, the unit should be unused original Metso/Valmet hardware rather than a newly manufactured generic substitute. A sealed Model 07 unit has been documented in secondary industrial inventory.
Request photographs of the actual module label and revision before purchasing.
Veteran’s Tech Trap Guide
⚠️ Trap 1: Confusing A413792 with an I/O module
One current web listing describes A413792 as an industrial control-interface module with analog inputs and digital outputs. That conflicts with several independent sources that identify A413792 as PEFT power-supply hardware.
PRO TIP: Search and quote the complete identification as “Metso/Valmet PEFT A413792”, not simply “A413792 module.”
⚠️ Trap 2: Assuming the output voltage from the system name
Do not assume A413792 is a generic 24 VDC supply simply because many Metso control cabinets use 24 VDC equipment.
The exact input range, output rails, current capacity, protection characteristics, and pin assignment need to come from the applicable system documentation or the actual module.
⚠️ Trap 3: Ignoring Model 07
At least one current inventory record identifies an A413792 Model 07 unit.
When sourcing a replacement, photograph the complete label. A base part-number match without revision/model confirmation is not sufficient for a legacy control-system power module.
⚠️ Trap 4: Treating any “PEFT” listing as equivalent
The PEFT designation is useful for identifying the product family, but it does not eliminate the need to check the exact A413792 part number, model, connector arrangement, and installed system.
Dynamic FAQ
Q1. What is the Metso A413792?
A413792 is identified in multiple industrial inventories as a Metso/Valmet PEFT power supply module used with legacy automation equipment.
Q2. What does PEFT mean on A413792?
PEFT is the module designation associated with A413792 in available Metso/Valmet spare-part inventories. The exact electrical architecture should be confirmed from the applicable system documentation rather than inferred from the acronym alone.
Q3. Is A413792 a PLC or I/O module?
The better-supported identification is power supply module, not CPU, analog input, or digital output module. Several independent inventory sources explicitly pair A413792 with “PEFT Power Supply Module.”
Q4. Is Model 07 available?
Yes. A current industrial inventory listing specifically identifies a Metso A413792 Power Supply Module Model 07 and describes the unit as sealed.
Q5. What are the input and output specifications?
Public sources located for this part do not provide sufficiently reliable OEM documentation for publishing exact input voltage, output voltage rails, current rating, or terminal pinout. Those values should be checked against the installed A413792 label, Metso/Valmet system documentation, or an OEM technical drawing.
Q6. How do I verify New Surplus A413792 authenticity?
Ask for photographs of the actual unit showing the Metso/Valmet label, A413792 part number, PEFT designation, Model 07 or other revision marking, connectors, and overall physical condition. A sealed original unit is preferable to a listing that only supplies a stock photograph.
Q7. What warranty should I request?
For legacy spare hardware, warranty terms depend on the supplier and stock condition. Confirm the warranty period, DOA coverage, test procedure, and return conditions before purchase. New Surplus status should also be distinguished from refurbished or previously installed stock.
