Description
Product Overview
The ABB UNC4672AV1 HIEE205012R1 is associated with an analog measuring card used in ABB UNITROL P excitation systems. ABB’s product identification and UNITROL P spare-parts references identify the corresponding UNC 4672A, V1 measuring interface under product ID HIEE205012R0001. Its role is to provide measurement functionality within the excitation-system architecture, where accurate signal acquisition supports monitoring and control of generator excitation.
For plant maintenance teams, this component should be treated as a system-specific measuring interface, not assumed to be a general-purpose PLC analog input card. The available public documentation does not establish its exact channel count, supported signal types, input ranges, conversion resolution, accuracy, or connector pinout. Those parameters must be checked in the hardware documentation and drawings for the specific UNITROL P installation. Do not rely on unverified supplier specifications when planning wiring changes or calibrating measurement circuits.
When purchasing the ABB UNC4672AV1 HIEE205012R1, resolve the part-number discrepancy before approving the order. Compare the board and packaging labels with the verified ABB product ID, confirm the V1 designation, and match the card to the cabinet bill of materials and installed hardware revision. Also check the card’s position, connected measurement circuits, and associated system configuration. For used or refurbished inventory, request clear photographs and documented inspection or functional-test results. A physical fit alone does not demonstrate that a measuring card is electrically or functionally suitable for the installed excitation system.
Product Introduction
The ABB UNC 4672A, V1 is documented as an analog measuring interface for the UNITROL P excitation system. Its exact signal characteristics and replacement compatibility must be established from the relevant system documentation.
Before ordering, verify the official product ID, revision marking, cabinet slot, and measurement-circuit references. This is particularly important when maintaining legacy generator-excitation equipment.

Frequently Asked Questions
Q1. What is the ABB UNC4672AV1 used for?
It is associated with the UNC 4672A, V1 analog measuring interface in the ABB UNITROL P excitation system.
Q2. Is HIEE205012R1 the verified ABB order number?
Not conclusively. The verified product ID in the available references is HIEE205012R0001. Treat HIEE205012R1 as unconfirmed until the physical label or ABB documentation establishes the mapping.
Q3. How many measuring interfaces are used in a UNITROL P unit?
The referenced UNITROL P spare-parts information lists two UNC 4672A, V1 measuring interfaces per unit. Confirm the configuration of the specific cabinet before ordering quantities.
Q4. What analog signals does the card support?
The available public references do not specify the exact signal types, channel count, or measurement ranges. Consult the hardware manual and measurement-circuit drawings for the installed system.
Q5. Can it replace another UNITROL P measuring card?
Only with documented confirmation. Verify the product ID, revision, slot assignment, connected circuits, and system configuration. Do not assume that cards with similar UNC designations are interchangeable.
Q6. Can the card be replaced while the system is running?
Hot-swap capability has not been confirmed for this card. Follow the applicable UNITROL P maintenance procedure and plant isolation requirements before removing or installing hardware.
Q7. What should buyers request when purchasing used or refurbished stock?
Request photographs of the actual board and packaging labels, confirmation of the complete part number and revision, a clear statement of condition, and available inspection or functional-test records.
Q8. What information is needed to confirm compatibility?
The most useful records are the UNITROL P system version, cabinet bill of materials, slot assignment, measurement-circuit drawings, and a photograph of the installed card label. These allow the supplied unit to be checked against the actual application before installation.
