Description
ABB UFD128A101 (3BHE012049R0101) – Control Interface Board for ABB Industrial Drive Cabinets
The ABB UFD128A101, ordering code 3BHE012049R0101, is a control/interface board engineered for ABB drive systems. From my experience, this board typically handles high‑reliability signal processing between the drive control core and the power section, with fiber‑optic links and isolated I/O designed for electrically harsh environments inside a drive cubicle. If you’re maintaining an installed ABB drive line, this unit tends to be a straight drop‑in replacement that helps cut downtime to a minimum.

Application Fields
This board is used in ABB industrial drive systems for process lines where uptime matters: steel and metals processing, mining and cement conveyors, pulp & paper winding lines, marine propulsion auxiliaries, and large HVAC or pumping stations. One thing I appreciate is how it slots into existing cabinets with minimal rewiring, which typically shortens the maintenance window on retrofit or spares projects.
Simulated client feedback: “We swapped in the UFD128A101 during a planned stop; fiber links reseated cleanly and the drive came up with previous parameters. Total downtime was under 90 minutes, including checks.”
Advantages & Value
- Reliability – Built for high‑EMI environments; stable operation in most cabinet conditions.
- Compatibility – Matches the original ABB part number 3BHE012049R0101 for straightforward replacement.
- Cost & uptime – Reduces unplanned downtime vs. third‑party workarounds; fits existing harnesses and optics.
- Support – Pre‑shipment test reports and technical guidance on installation and parameter alignment if needed.
Installation & Maintenance
- Environment – Install in a sealed drive cabinet with adequate ventilation; keep ambient within 0…+55°C.
- Power – Use a clean 24 VDC control supply; verify grounding and shield terminations.
- Wiring – Route fiber‑optic cables with gentle bend radius; avoid tight bundles with power cables. Reseat connectors until you feel a positive click.
- ESD safety – Handle using grounded wrist straps and antistatic packaging; avoid touching component leads.
- Routine care – Quarterly visual inspection for dust; clean with dry air. Check fiber ends for contamination. Back up parameters after any firmware or board change.
- Firmware/parameters – Align board firmware and drive application versions where applicable; restore saved parameters after replacement.
Quality & Certifications
ABB manufacturing typically follows ISO 9001 processes, with products designed for CE compliance. Components on these boards are often UL‑recognized and RoHS‑compliant depending on revision. Warranty coverage is 12 months from shipment; defective units can be exchanged or repaired after evaluation.
Recommended Supporting Items
- 24 VDC industrial power supply with sufficient headroom for control loads
- ABB‑compatible fiber‑optic patch leads and dust caps
- ESD‑safe tool kit and antistatic storage boxes for spare boards
If you’re cross‑checking part compatibility, share the drive cabinet type and current firmware/application version. We can verify against UFD128A101 (3BHE012049R0101) to avoid surprises during the service window.
