Identification caution
The available evidence is unusually inconsistent for UAC389 HIEE410506P104. One parts reference explicitly identifies HIEE410506P104 as an “input and output board,” while another identifies the same part as a UAC389 processor module.
There are also listings calling it a power supply or intelligent control module and attaching detailed specifications such as ARM9, Linux, Ethernet, RS-232, RS-485, 4–20 mA inputs, and 24 VDC operation. I would not publish those values as confirmed specifications for HIEE410506P104 because I could not corroborate them with an ABB primary document.
Product Introduction
The ABB UAC389 HIEE410506P104 is a legacy ABB electronics assembly associated with the UAC389 designation. Available technical references identify it as a processor/control-related module, while another parts database categorizes HIEE410506P104 as an input/output board. That conflict makes the complete ABB designation and physical nameplate especially important when identifying the component.
From a procurement perspective, this is a part where guessing from a generic online description creates unnecessary risk. The exact host equipment, board revision, connector arrangement, and neighboring ABB assemblies should be checked before approving a replacement. The part also appears in ABB legacy drive/control parts references alongside boards such as XVC769, SCYC51204, SCYC51213, and UFC921A.

Application Scenarios & Field Pitfalls
Engineering Pain Point
The primary difficulty with is not finding a board with the same physical size; it is establishing exactly which ABB system function the installed board performs. Public secondary sources use different classifications for the same identifier.
Typical Applications
- Legacy ABB drive control cabinets requiring board-level replacement.
- Industrial power-control equipment where electronics remain installed.
- Plant maintenance and retrofit work involving discontinued ABB assemblies.
- Spare-parts restoration where the original board revision must be preserved.
Technical Pitfalls to Avoid
- Do not automatically classify it as a 24 VDC power supply. That description appears in reseller material, but the supporting technical parameters are not sufficiently authoritative.
- Do not assume it is a generic PLC processor. The term “processor module” appears in secondary documentation, but that does not establish compatibility with ABB AC 800M, Freelance, or other PLC platforms.
- Do not mix with XVC769 AE101. Some ABB parts references display 3BHE006373R0101 / XVC769 AE101 / together, but this does not establish that the three identifiers are interchangeable.
- Use the physical board markings for final verification. Check the designation, number, revision code, connectors, and the assembly position in the host equipment before replacement.

Procurement Check
For ABB , I recommend purchasing against the full designation rather than a generic functional description:
ABB —
Before approving the part, verify the host ABB equipment, board revision, connector layout, physical board markings, neighboring modules, and original system documentation. The available sources do not justify publishing specific voltage, processor, memory, Ethernet, analog-I/O, or operating-temperature figures as guaranteed specifications for this exact part.
