Allen-Bradley GU-D15 80173-110-01 Gate Commutated Turn-Off Board – PowerFlex Drive Series
When a Gate Commutated Turn-Off (GCT) board fails inside a high-power AC drive, the consequences are immediate and severe: the drive trips on an unrecoverable gate fault, the motor stops dead, and the entire production line grinds to a halt. In steel mills, paper machines, mining conveyors, and marine propulsion systems, an unplanned stoppage of even one hour can cost tens of thousands of dollars. The Allen-Bradley GU-D15 80173-110-01 G651885A is the precision-engineered board that stands between continuous operation and catastrophic downtime.
The GU-D15 80173-110-01 G651885A occupies a critical position within Rockwell Automation’s high-power drive architecture. As the gate commutation control interface, it manages the precise firing sequencing of GCT thyristors — the power semiconductors responsible for converting AC to DC in regenerative and non-regenerative drive topologies. This board is not a commodity component; it is a tightly toleranced, firmware-coordinated assembly that must meet Rockwell’s OEM specifications to ensure safe, synchronized power conversion. Its continued availability in the global aftermarket makes it one of the most sought-after legacy drive boards among maintenance engineers worldwide.

Key Features & Benefits
- OEM-Matched Gate Timing: Maintains the precise gate pulse width and phase angle required by the drive’s DSP controller, preventing nuisance trips and protecting power semiconductors.
- Robust Signal Isolation: Optical isolation between the low-voltage control logic and high-voltage gate drive circuits ensures personnel safety and signal integrity in electrically noisy environments.
- Direct Drop-In Replacement: Designed to the original Rockwell mechanical and electrical footprint — no wiring modifications, no firmware re-flashing required in most applications.
- Tested Before Shipment: Every board dispatched from Konmask undergoes functional bench testing to verify gate pulse output, isolation resistance, and board-level communication.
- Long-Term Availability: Konmask maintains strategic stock of legacy Allen-Bradley drive boards, providing supply continuity for plants running equipment beyond OEM support windows.
Industry & Equipment Applications
- Steel & Metals: Rolling mill main drives, coiler/uncoiler drives, and DC motor field excitation systems.
- Mining & Minerals: Conveyor belt drives, crusher drives, and hoist control systems.
- Pulp & Paper: Winder/unwinder drives, refiner drives, and dryer section drives.
- Marine & Offshore: Thruster drives, winch drives, and dynamic positioning motor controllers.
- Oil & Gas: Pump and compressor variable-speed drives in hazardous-area installations.
- Water & Wastewater: Large pump station VFDs requiring regenerative braking capability.
System Integration & Compatible Parts
The GU-D15 80173-110-01 G651885A is designed to integrate within Allen-Bradley’s high-power drive chassis. When planning a repair or spare-parts strategy, consider stocking the following complementary boards to minimize future downtime risk:
- Firing board / pulse amplifier boards (drive-model specific)
- Power supply boards for the drive control rack
- Feedback interface boards (encoder, resolver, or tachometer input)
- I/O expansion boards for the drive’s PLC interface
Contact our technical team with your full drive nameplate data and we will map out a complete critical-spares list tailored to your installation.
Our Quality Assurance Process
- Incoming Inspection: Visual inspection for physical damage, corrosion, burnt components, and counterfeit markers.
- Electrical Bench Test: Power-on test verifying gate pulse outputs, supply rail voltages, and isolation resistance per OEM test points.
- Functional Verification: Where test fixtures are available, boards are cycled through simulated drive operating conditions.
- ESD-Safe Packaging: Boards are packed in anti-static bags with foam cushioning and clearly labeled with part number and test date.
- Documentation: Test report and condition certificate issued with every shipment upon request.
