Available part records identify 3BHE014967R0001 / UNS2880B-P V1 as an ABB COB control board. One technical listing describes it specifically as a control/operator board for UN5000/UNITROL systems.
V1 Versus V2 — Procurement Warning
This part requires special attention because secondary databases are inconsistent. ABB-related parts indexes list UNS2880B-P V2 as 3BHE014967R0002, while V1 is listed as 3BHE014967R0001.
Some suppliers nevertheless advertise 3BHE014967R0002 as “UNS2880B-P V1.” That is a catalog-data conflict, not evidence that V1 and V2 are interchangeable. For procurement, the material number printed on the existing board should take precedence over a reseller’s V1/V2 text.
Product Introduction
The ABB UNS2880B-P V1 is a COB control-board assembly associated with ABB UN5000/UNITROL generator excitation systems. It is a board-level control component rather than a conventional AC 800M I/O module, PLC CPU, or standalone drive.
In a replacement application, the host excitation system and exact board revision matter more than generic electrical specifications. The available documentation does not provide enough authoritative evidence to safely publish detailed voltage, I/O-channel, Ethernet, or protocol specifications for the exact V1 assembly, so those values should be taken from the installed system documentation and board nameplate rather than copied from inconsistent supplier listings.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
The biggest risk with is incorrect identification. Several secondary sources mix the V1 and V2 material numbers, while others describe the board as a generic PLC or servo-drive module. Those descriptions are not reliable enough for a field replacement decision.
Typical Applications
- ABB UN5000 generator excitation systems
- ABB UNITROL excitation control equipment
- AVR and excitation-control hardware
- Maintenance replacement of legacy ABB COB control boards
Technical Pitfalls to Avoid
- Verify the material number, not only “ V1.”
The strongest evidence associates V1 with 3BHE014967R0001, while 3BHE014967R0002 is separately identified as V2. - Do not assume generic PLC specifications.
Listings claiming 110/220 VAC input, 300 W output, specific Ethernet protocols, or broad temperature ratings are not adequately supported for this exact board and should not be used as procurement specifications. - Check the complete excitation-system architecture.
The COB board works within a larger excitation-control assembly. Confirm the mating boards, firmware/configuration, connectors, rack or mounting arrangement, and system revision before installation. - Do not substitute V2 solely because the part number looks similar.
Even if V2 is physically compatible, the installed excitation system may depend on revision-specific hardware or firmware behavior. Treat any V1-to-V2 substitution as an engineering compatibility check, not a routine part swap.

Procurement Check
Before approving an , verify:
- Exact designation:
- Material number: 3BHE014967R0001
- Board revision and PCB marking
- Host system: UN5000 / UNITROL
- Existing excitation-system configuration
- Firmware/configuration compatibility
- Mating boards and connectors
- Board mounting arrangement
- Existing parameter/configuration backup
- Whether the proposed replacement is actually V1 or V2
- Photographs of the original board label when the material number is unclear
Recommended procurement description:
ABB V1, 3BHE014967R0001, COB Control Operator Board / Control PCB Assembly for ABB / UNITROL Generator Excitation System.
The key procurement point is revision control. For this part, I would not approve a quotation simply stating “ V1.” The safest purchase description is V1 + 3BHE014967R0001, with the board label and host excitation-system configuration checked before shipment. The frequent appearance of 3BHE014967R0002 under V1 listings is a clear reason to verify the physical nameplate rather than trusting catalog text alone.
