Description
- Model: UAC389AE02
- ABB Part Number: HIEE300888R0002
- Part Type: Pulse Amplifier Interface (PAI) / control interface module
- Application: ABB industrial drive and automation systems
- Condition: New surplus or refurbished availability should be confirmed by lot
- Weight: Approximately 1.1 kg for the listed transport unit; verify actual packed weight before shipment.
Technical Introduction
A failed interface module can stop an otherwise serviceable ABB control or drive assembly from operating correctly.
The ABB UAC389AE02 HIEE300888R0002 is identified in available industrial spare-parts references as a Pulse Amplifier Interface (PAI) and is also marketed as a control/interface board. Its role is associated with conditioning and interfacing pulse-related signals within ABB automation and drive architectures. Because documentation for this legacy part is limited in publicly indexed sources, buyers should verify the installed system, board designation, connector arrangement, and application before treating it as a direct replacement.
The part number appears in industrial automation inventories alongside ABB drive and control-system components, making it relevant for maintenance teams supporting legacy ABB equipment where an exact board-level replacement is preferred over a wider system migration.

Field Engineer’s Tech Notes
- Do not treat the part number alone as proof of compatibility. Before installation, compare the existing board’s full identification label, revision information, connectors, and cabinet documentation against the replacement. The UAC389AE02/HIEE300888R0002 is described inconsistently across secondary-market listings, so application-level verification is recommended.
- Preserve the existing signal configuration. If the module is being replaced in a pulse-interface application, document connector wiring and signal routing before removal. A visually identical replacement can still create commissioning problems if the installed system uses a different board revision or signal configuration.
Adaptive QA & Testing Protocol
For an UAC389AE02 HIEE300888R0002, inspection should focus on board condition, connectors, identification labels, and evidence of previous electrical damage.
For tested units, the QA process can include:
- Visual inspection for corrosion, cracked components, damaged connectors, and PCB contamination.
- Verification of the ABB model and HIEE part number against the purchase specification.
- Connector and terminal inspection before functional testing.
- Power-up testing where a suitable OEM-compatible test setup is available.
- Interface/pulse-signal verification appropriate to the installed application.
- Functional confirmation of associated communication or control interfaces when supported by the test configuration.
- Recording of test results and unit identification for traceability.
Test reports, inspection photographs, and available test videos can be provided upon request.

Buyer’s FAQ
Is UAC389AE02 HIEE300888R0002 a direct replacement for my existing board?
It may be, but direct replacement should be confirmed from the existing board revision, system application, connector configuration, and OEM documentation. The part number alone should not be used to approve a substitution.
Is this part available new or refurbished?
Availability and condition vary by inventory lot. New surplus, new old stock, and refurbished units may exist in the aftermarket. Confirm the exact condition before placing the purchase order.
Can you provide a test report before shipment?
Yes. For units that undergo functional testing, a test report and supporting inspection evidence can be requested before shipment, subject to the available test setup.
What should I provide when requesting a replacement?
Send the / HIEE300888R0002 part number, quantity, existing equipment/system model, nameplate photographs, required condition, destination, and target delivery date. This allows compatibility, stock condition, and lead time to be checked before quotation.
