Description
ABB UNS0017A-P.V1 HIEE305106R0001
Product Introduction
The ABB UNS0017A-P.V1 HIEE305106R0001 is a dedicated firing unit used in ABB UNITROL 5000 excitation systems. ABB’s own spare-parts documentation identifies the exact order number HIEE305106R0001 as UNS 0017 A-P V1, with the description “Firing unit.” This places the board directly in the converter firing-control portion of the excitation system rather than in the general-purpose PLC I/O category.
The ABB HIEE305106R0001 UNS 0017 A-P V1 is associated with the controlled power-converter section used by generator excitation equipment. In a thyristor-based excitation system, the firing circuitry is responsible for generating correctly timed gate-control signals for the power semiconductor stage. That makes the board’s hardware configuration directly relevant to converter operation. ABB’s spare-parts documentation also lists a later set of UNS 0017 A-P V1 firing-board order numbers with different BOD ratings, including 1000 V, 1200 V, 1400 V, 1600 V, 1800 V, 2000 V, 2200 V, 2400 V, and 2600 V versions.
For procurement, the complete UNS0017A-P.V1 / HIEE305106R0001 identification should be retained. The presence of other UNS 0017 A-P V1 order numbers demonstrates why the short model designation alone is insufficient for substitution. A board that appears physically similar may have a different BOD configuration or electrical application. ABB specifically lists HIEE305106R0001 as a UNITROL 5000 spare part, while newer order numbers in the same family carry explicit voltage-related configurations.

Main Features and Engineering Considerations
Dedicated Thyristor Firing Function
The ABB UNS0017A-P.V1 is a specialized firing unit within the UNITROL 5000 converter architecture. It should not be treated as a standard control processor, analog-output module, or generic gate-driver card.
Part of the Converter Control Chain
In a controlled thyristor excitation system, the firing stage has a direct relationship with the power converter. Correct firing timing and synchronization are therefore essential to the intended converter operation. A fault in this section can manifest as excitation-control problems rather than simply a communication or I/O fault.
Exact Order Number Matters
ABB identifies specifically as the UNS 0017 A-P V1 firing unit. The same ABB documentation lists later UNS 0017 A-P V1 firing-board versions under different order numbers and different BOD voltage ratings.
This is a significant procurement issue. Do not replace solely because another board carries the same “UNS 0017 A-P V1” designation.
BOD Configuration Requires Verification
ABB lists newer versions with 1000 V, 1200 V, 1400 V, 1600 V, 1800 V, 2000 V, 2200 V, 2400 V, and 2600 V BOD configurations. The correct BOD level depends on the associated power-converter design. It should be confirmed from the original board marking, excitation-system documentation, and cabinet electrical drawings.
UNITROL 5000 Compatibility
ABB categorizes under UNITROL 5000 spare parts. The associated converter topology and excitation-system configuration should therefore be established before purchasing a replacement.
Field Replacement
Before removing the installed board, record its complete identification, PCB revision, connector arrangement, and cabinet location. Photograph the wiring and connector positions. After replacement, the excitation system should be checked for converter diagnostics and firing-related faults before the generator is returned to normal operation.
Do Not Assume Hot-Swap Capability
Secondary sellers sometimes describe this board as hot-swappable, but the available ABB documentation does not establish that claim for . Treat the firing unit as an energized-power-converter component and follow the site’s approved shutdown, isolation, and discharge procedures.
Application Scenarios
- ABB UNITROL 5000 excitation systems
- Synchronous generator excitation
- Static excitation systems
- Thyristor-controlled excitation converters
- Generator voltage-regulation systems
- Power-generation plants
- Excitation-system maintenance
- Legacy UNITROL 5000 refurbishment
- Planned outage spare-part replacement
- Converter firing-control troubleshooting
Engineer’s Guide: Field Pitfalls
Do not classify this as a generic PLC control board. ABB explicitly identifies it as a Firing Unit within UNITROL 5000.
Do not substitute by model name alone. Multiple UNS 0017 A-P V1 order numbers exist.
Check the BOD configuration. ABB lists later versions with different BOD voltage ratings from 1000 V through 2600 V.
Verify the converter topology. The firing unit must correspond to the installed power-converter arrangement and excitation-system design.
Do not infer the board’s supply voltage from the generator voltage. The firing electronics and power semiconductor circuit have their own defined electrical interfaces.
Inspect the complete board marking. Record , the UNS designation, revision information, and any additional PCB identification before ordering a replacement.
Test the complete excitation chain after replacement. A firing-board replacement should be followed by appropriate converter and excitation checks rather than simply confirming that the board powers up.
Frequently Asked Questions
What is ABB UNS0017A-P.V1?
It is the designation for an ABB UNS 0017 A-P V1 Firing Unit used in UNITROL 5000 excitation equipment. ABB identifies the order number as .
What is ?
is ABB’s identification/order number for the UNS 0017 A-P V1 Firing Unit.
Is an I/O module?
No. It is documented as a Firing Unit, not a conventional analog or digital I/O module.
Which ABB system uses .V1?
ABB lists under the UNITROL 5000 family of excitation-system spare parts.
Are all UNS 0017 A-P V1 boards interchangeable?
No. ABB lists several later order numbers under the same general UNS 0017 A-P V1 designation with different BOD voltage configurations. The complete order number and converter configuration must be matched.
Is the same as the later 3BHE035495R0010?
They share the UNS 0017 A-P V1 designation, but they should not be treated as automatically interchangeable. ABB identifies 3BHE035495R0010 as a Firing Board with 1000 V BOD, whereas is separately listed as the original Firing Unit.
Procurement Note
For purchasing, specify the complete identification:
ABB UNS 0017 A-P, V1 — — Firing Unit — UNITROL 5000
Before approving a replacement, verify:
- Exact UNITROL 5000 system configuration.
- Existing board order number and revision.
- Converter topology and associated thyristor stack.
- Applicable BOD voltage configuration.
- Connector and cabinet position.
- Any supersession information supplied by ABB for the installed system.
The most important point is not to substitute another UNS 0017 A-P V1 board solely because the front designation looks identical. ABB’s own parts documentation confirms multiple electrically differentiated versions in this family.
