Product Introduction

A sensor-control board failure can leave an otherwise serviceable ABB drive or automation assembly unavailable for operation. The ABB 086339-501 is identified as a PWA, Sensor Micro Intel, also described by industrial automation repair specialists as an ABB SMI Sensor Micro Intel PCB.

For maintenance teams supporting older ABB equipment, this part number provides a direct identification point when sourcing a replacement PCB. It is listed within VFD spare-part references, so procurement should be based on the complete 086339-501 marking rather than PCB appearance alone.

The product description and listed physical specifications are documented by industrial automation parts references.

Application Scenarios & Pain Points

For legacy ABB drive maintenance, exact board identification matters. The 086339-501 is cataloged as an ABB SMI Sensor Micro Intel PCB, making it relevant when a failed sensor-related board needs to be replaced without changing the surrounding equipment.

In VFD spare-parts inventory, the board can serve as a replacement component for equipment requiring the specific 086339-501 assembly. Available product references place it directly within ABB VFD spares.

When intermittent sensor behavior appears, maintenance personnel should inspect the PCB together with its connectors and associated wiring. This approach is particularly important in cabinets operating around 50°C or higher, where accumulated thermal stress can accelerate electronic component aging.

For repair-center applications, the part is also listed by an industrial electronics repair provider with completed repair records, indicating that the 086339-501 is encountered as a serviceable PCB assembly rather than only as a complete equipment component.

Common Error Codes & Diagnostic Symptoms

Symptom: Sensor-related control function becomes intermittent
→ Diagnosis: A PCB-level fault, connector problem, or associated sensor circuit can interrupt normal SMI electronic operation.
→ Action: Check supply, connectors, wiring, and the board; replace the 086339-501 when PCB failure is established.

Symptom: Sensor information is no longer processed correctly
→ Diagnosis: Failure within the SMI Sensor Micro Intel PCB can prevent the associated electronic circuitry from handling the expected sensor signal.
→ Action: Verify the complete board identification and replace the defective PCB.

Symptom: Equipment remains unavailable after external wiring checks
→ Diagnosis: If external connections and incoming electrical conditions are correct, an internal PCB fault becomes a primary suspect.
→ Action: Install a correctly identified 086339-501 and perform system-level functional testing.

Important: No reliable source located for this exact part provides a manufacturer-specific numeric error-code list. Numeric ABB fault codes should therefore be taken from the manual for the host equipment, not assigned directly to the 086339-501 PCB.

Cross-Reference & Lifecycle Migration

• Primary replacement identifier: ABB 086339-501.
• Product description match: PWA, Sensor Micro Intel / SMI Sensor Micro Intel PCB.
• Related ABB numbers: 086339-001, 086345-001, 086348-001, 086362-001 and other nearby numbers appear in supplier catalogs. They should not be treated as direct substitutes without equipment-specific compatibility verification.
• Revision interchangeability: No documented revision matrix was located for this exact part number. Match the installed board’s complete part marking before replacement.
• Firmware: This PCB is identified as a hardware PWA/PCB; no reliable source reviewed specifies a firmware-flashing procedure for 086339-501.
• Lifecycle position: The part appears primarily through industrial automation spare-parts and repair channels rather than current-generation ABB product documentation. For plants retaining legacy equipment, maintaining a spare can reduce procurement exposure.

Field Engineer’s Tech Notes

Warning 1 — Verify the entire part number.
Do not substitute another ABB board simply because the PCB dimensions or connector arrangement looks similar. The distinction between 086339-501 and related 086xxx part numbers can be critical to system compatibility.

Warning 2 — Protect the board during installation.
Handle the PCB under ESD-controlled conditions. Before energizing the equipment, inspect every connector and mating socket for oxidation, bent contacts, contamination, or mechanical damage (a poor connection can mimic a failed replacement board).

Strict QA & Testing SOP

1. Part-number inspection — Verify the ABB marking 086339-501 against the purchase requirement.
2. Label documentation — Photograph the identification label and any revision or serial markings.
3. PCB visual inspection — Examine connectors, solder joints, components, traces, and the PCB surface for physical damage.
4. Contamination check — Inspect for corrosion, moisture residue, dust accumulation, or evidence of previous overheating.
5. Electrical inspection — Verify applicable supply and continuity conditions against the host-equipment documentation.
6. Connector inspection — Check mating connectors and terminal interfaces before connecting the board.
7. Functional testing — Install the PCB into a compatible test assembly and verify the associated sensor/control functions.
8. Operational observation — Monitor startup, sensor response, control behavior, and intermittent symptoms during the test period.
9. Final inspection — Record test results and photograph the tested unit.
10. ESD-safe packaging — Place the PCB in antistatic protective packaging with suitable mechanical cushioning for transportation.

Test videos are available upon request for units that undergo functional testing.

Buyer’s FAQ

Q: Can the 086339-501 be hot-swapped?
A: Do not assume it can. Unless the documentation for the specific ABB host equipment explicitly permits energized PCB replacement, isolate power and follow the approved maintenance procedure.

Q: How can I verify that the replacement is the correct ABB board?
A: Check the complete 086339-501 part number on the board and compare the physical revision and connector arrangement with the installed unit. Avoid selecting a replacement solely from a similar product photograph.

Q: Is this a current-generation ABB control module?
A: The available references identify the unit as an ABB SMI Sensor Micro Intel PCB and list it through spare-parts and repair channels. It is best treated as a legacy equipment spare for procurement planning.

Q: What warranty can be provided with a replacement unit?
A: Warranty terms depend on the supplier and unit condition. For example, EU Automation advertises a 12-month warranty for its 086339-501 offering, while Lektronix states a 12-month whole-unit warranty for its repair and spare services. These are supplier warranties and should not be represented as an ABB OEM warranty unless specifically documented as such.
