Description
ABB UAD215A102 (3BHE026284R0102) – High-speed analog interface board for PEC-based drive and power control systems
The ABB UAD215A102, part number 3BHE026284R0102, is a plug-in control board typically used as an analog acquisition/interface module within ABB PEC platforms and drive/excitation cabinets. From my experience, UAD2xx cards show up in AC 800PEC-based applications and medium-voltage drive retrofits where fast, precise analog feedback is required for closed-loop control. If you’re maintaining an installed ABB system, this module is often ordered as a like-for-like replacement to keep loop performance stable and avoid time-consuming revalidation.
Order Placement Process and Guarantees
- Warranty: 365 days
- Lead time: 1 week for in-stock items; no more than one month at the latest
- Payment terms: 50% advance payment; full payment prior to delivery
- Express shipping: FedEx, UPS, DHL
- Pre-shipment checks: Visual/ESD handling, basic power-on verification when applicable, and secure packing for transit
Key Features
- Purpose-built for ABB PEC ecosystems: Designed to operate as a system board in ABB control/drive cabinets, not a standalone PLC I/O.
- Fast analog acquisition: Suited for feedback and interlocks in drives, excitation systems, and high-power converters where deterministic response matters.
- Backplane integration: Interfaces via the host backplane, which simplifies wiring and reduces field-side complexity.
- Drop-in maintenance spare: In many cases you can replace like-for-like (same type code/revision) and restore functionality with minimal downtime.
- Industrial-temperature design: Typically specified for control cabinet environments common to ABB drives and power control systems.
- Diagnostics at a glance: You might notice basic status/health indicators onboard, making first-line checks faster for maintenance teams.

Application Fields
This board is commonly used in ABB PEC-based control systems supporting:
- Medium-voltage drives and converters (e.g., high-power motors, rolling mills, marine propulsion)
- Excitation and generator control where fast analog feedback improves stability
- FACTS and grid-tied power electronics (STATCOM/SVC) where deterministic analog sampling is critical
- Retrofit projects on installed ABB cabinets requiring form-fit-function replacement
“We swapped in a UAD215A102 during a planned shutdown. The drive came back up cleanly with our existing parameters—no surprises, which is exactly what we hoped for.” — Maintenance Supervisor, steel plant
Advantages & Value
- Reliability in service: Proven in demanding, 24/7 environments; seems to be very tolerant of cabinet conditions when installed correctly.
- Compatibility: Drop-in replacement for the same type code and revision helps avoid control re-tuning and downtime.
- Cost control: Keeping to OEM architecture typically reduces engineering hours vs. redesigning interfaces.
- Lifecycle support: Easier spare pooling and revision management across multiple cabinets or sites.
Installation & Maintenance
- Cabinet environment: Install in a clean, ventilated control cabinet; maintain ambient 0…+55 °C and avoid condensation.
- Backplane & seating: Power down, observe ESD precautions, and seat the board firmly in the specified slot; secure all retention hardware.
- Wiring: Use the original harness/connectors; verify analog signal ranges and shielding practice (twisted, shielded pairs for low-noise feedback).
- Revision matching: Match type code and hardware revision to the existing system. In most cases, keeping the same revision avoids requalification.
- Routine checks: Inspect connectors quarterly, clean dust with dry air, and log any status LED anomalies during start-ups.
- Firmware/parameters: If your system manages board-specific parameters, back up prior to replacement and validate after power-up.
Quality & Certifications
- Manufactured under ISO 9001 quality systems (ABB)
- CE marking for EMC/safety applicable to the complete cabinet/system
- RoHS compliant components in typical ABB builds
- UL/CSA recognition may apply at the cabinet level rather than the individual board
- Supplied with a 365-day warranty
