Description
Product overview
The ABB 3BHE039426R0101 UF C912 A101 EOI protection board is an ABB drive spare associated with medium-voltage power-conversion equipment. ABB’s product information identifies the item by the type designation UF C912 A101: EOI and classifies it as a protection board within its drive spare-parts portfolio. It is not a general-purpose PLC input/output module; replacement decisions should be based on the installed drive configuration and the board’s exact identification.
For maintenance teams supporting ABB ACS2000 and ACS6000 equipment, the main purchasing consideration is exact application compatibility. Available product information identifies 3BHE039426R0101 for ACS2000 and certain ACS6000 configurations, but it does not establish that the board is interchangeable across every drive variant. In particular, the application needs to be checked for ACS6000 synchronous-drive configurations. ABB’s product information also specifies that the drive serial number is required before ordering, making the nameplate and installed hardware details important parts of the procurement process.
When sourcing the ABB 3BHE039426R0101, confirm the complete order number, type designation, physical board markings, and the drive model and serial number before committing to a replacement. Ask the supplier to identify the actual condition of the offered unit and state whether functional testing or inspection records are available. A matching part number is a necessary identification check, but it does not independently establish the board’s condition, revision suitability, or correct operation in a particular drive. For equipment supporting critical processes, confirm compatibility with the applicable ABB documentation or service channel before installation.
Product introduction
The UF C912 A101 is cataloged as an EOI protection board. It belongs to the spare-parts category for ABB drive equipment, so its application should be assessed in the context of the host converter rather than by treating it as a standalone automation controller. Publicly available listings do not consistently document the board’s detailed electrical characteristics, connector pinout, firmware requirements, or complete protection logic. Those parameters should not be inferred from unrelated boards or generic drive specifications.
For a planned replacement, compare the removed board with the proposed spare before installation. Record the full part number, type designation, revision markings, connector arrangement, and any visible damage. Confirm that the drive-specific replacement instructions permit the proposed part, then follow the equipment manufacturer’s isolation, handling, installation, and commissioning procedures. This is particularly important for medium-voltage drives, where an incorrectly selected component or an unverified installation can extend downtime and create additional equipment risks.

Related products and replacement considerations
- 3BHE039426R0111 — UF C912 A111: ABB identifies this as a one-to-one replacement for 3BHE039426R0101 in ACS2000 applications. ABB notes that the R0111 version does not support SSI encoder functionality, which it says is not used in ACS2000. Confirm the installed application before substituting.
- ABB ACS2000 medium-voltage drives: Relevant host equipment for application and replacement verification.
- ABB ACS6000 drives: Compatibility depends on the particular configuration; check the drive serial number and whether the unit is an asynchronous-drive (AD) or synchronous-drive (SD) application.
These are related parts or equipment families, not universal substitutes. Do not assume compatibility based solely on a shared manufacturer or similar type designation.
Frequently asked questions
Q1: What is ABB 3BHE039426R0101?
It is the ABB UF C912 A101 EOI protection board, cataloged as a drive spare part. Its suitability must be verified against the host drive configuration.
Q2: Which drives use this part?
Available ABB product information associates it with and selected ACS6000 applications. The exact drive model and configuration should be confirmed before ordering.
Q3: Can 3BHE039426R0111 replace 3BHE039426R0101?
ABB identifies 3BHE039426R0111 (UF A111) as a one-to-one replacement for . ABB notes the absence of SSI encoder support on the R0111 version and states that does not use this function. Do not extend this substitution to other applications without verification.
Q4: What information is required to confirm compatibility?
Provide the complete drive model, drive serial number, existing board’s full part number and type designation, and any visible revision markings. ABB’s product information specifically states that the drive serial number is needed before ordering.
Q5: Are the operating voltage and power consumption confirmed?
They are not confirmed by the cited ABB catalog entry. Obtain the applicable technical documentation rather than relying on unverified third-party specifications.
Q6: What should be checked when receiving a replacement board?
Verify the order number and type designation, inspect the PCB and connectors for damage, confirm the declared condition, and request any available inspection or functional-test records. Complete compatibility and commissioning checks under the drive manufacturer’s procedures.
Q7: Does a matching part number guarantee that the board is ready to install?
No. Part-number matching establishes identity, not operating condition or application suitability. The drive configuration, replacement authorization, physical condition, and available test evidence still need review.
Procurement recommendation
Before requesting a quotation for ABB 3BHE039426R0101, provide the drive serial number and the existing board’s identification details. Ask the supplier to confirm:
- Exact order number and type designation.
- Offered condition: new, unused surplus, refurbished, or used.
- Whether inspection or functional testing was performed, and what evidence is available.
- Whether the proposed part is approved for the specific host-drive configuration.
- Actual stock status, dispatch estimate, warranty terms, and return conditions.
For an replacement, ask specifically whether ABB’s documented 3BHE039426R0111 / UF A111 alternative is applicable to the installed unit. For equipment—especially an SD configuration—obtain application-specific confirmation before purchase. This reduces the risk of ordering a physically similar board that is not suitable for the intended drive.
