Description
- Model: B09261
- Brand: ABB
- Part Type: ABB automation spare part
- Identification: Exact functional designation requires OEM documentation or nameplate verification
- Application: Legacy industrial automation equipment
- Compatibility: Verify the complete assembly, revision, and installed equipment before ordering
Technical Introduction
Part-number accuracy matters here because ABB B09261 is indexed in ABB-related industrial automation catalogs, but the publicly available records reviewed do not provide enough reliable technical information to identify its exact electrical function, system family, or interface specification. It appears alongside established ABB automation references such as LDMUI-01, UFC921A, UAC389, NTAC-02, and other ABB spare references, confirming that the number is used within an ABB automation spare-part catalog context.
For procurement and maintenance purposes, B09261 should therefore be quoted against the exact part number, with the host equipment and existing nameplate checked before release. This is especially important for legacy systems where a short internal or assembly reference may not contain the complete ordering information.
Best Suited For

Field Engineer’s Tech Notes
- Do not substitute based on the short number alone. B09261 should be matched against the equipment nameplate, assembly reference, revision information, and any ABB parts list available at the site. A visually similar replacement can still have different electrical or mechanical characteristics.
- Photograph the original before removal. Record connector locations, PCB markings, terminal assignments, jumpers, switches, and any secondary ABB identification labels. For legacy equipment, those details can be more useful than the short ordering reference when validating the replacement.
Adaptive QA & Testing Protocol
Because the exact function of is not sufficiently established from the available public records, testing should be tailored after the assembly type is confirmed.
Incoming QA should include part-number verification, visual inspection, connector and mechanical inspection, label/serial-number recording, and comparison with the customer’s installed unit. Functional testing should then follow the applicable ABB equipment test procedure rather than applying a generic PLC or I/O test.
Inspection photographs, test documentation, and available test videos can be provided upon request.
Buyer’s FAQ
Q: Is ABB a direct replacement for my existing unit?
A: Direct replacement should be confirmed from the complete equipment documentation and the installed part identification. The number alone is not sufficient to establish interchangeability.
Q: Is this part available as New Surplus or refurbished?
A: Availability and condition depend on current inventory. New OEM, New Surplus (NSFP), and refurbished stock should be quoted separately.
Q: Can you verify compatibility before shipment?
A: Yes. Provide the host ABB equipment model, existing part label, revision information, and clear photographs of the installed unit for a more reliable compatibility check.
Q: Can inspection or testing records be supplied?
A: Yes. Request available inspection photos, test reports, or test videos with the quotation.
