ABB UAD215A106 (3BHE026284R0106) – I/O and Fiber-Optic Interface Board for AC 800PEC-Based Power Electronics

The ABB UAD215A106, part number 3BHE026284R0106, is an interface board used on the ABB AC 800PEC platform to bridge fast power-electronics control with robust field I/O and fiber‑optic links. From my experience, this board is typically selected in medium-voltage drives, converters, and excitation systems where deterministic I/O timing and noise-immune signaling are essential.

Key Features

• Designed for AC 800PEC – Integrates directly with ABB’s high‑speed power electronics controller for drives and converter applications.
• Mixed I/O capability – Typically provides a combination of digital and analog channels for measurements, control signals, and interlocks.
• Fiber‑optic interfaces – Noise‑immune links for gate units and remote I/O where electrical isolation and EMC robustness are needed.
• 24 VDC system power – Uses the standard 24 VDC control supply commonly available in industrial cabinets.
• Industrial EMC robustness – Layout and signaling intended for harsh electrical environments around high-power converters.
• Module serviceability – Board-level replacement keeps downtime short and maintenance straightforward in many cases.

Technical Specifications

Application Fields

• Medium‑voltage drives (e.g., ACS series) where fiber‑optic gate control and fast I/O are required.
• Static converters and rectifiers in metals, mining, and marine propulsion systems.
• Grid‑tied power electronics (SVC/STATCOM, test benches) using AC 800PEC control.
• Excitation systems and high‑power test stands needing deterministic I/O timing.

You might notice that many teams keep a spare UAD215A106 on the shelf; in most cases it reduces MTTR dramatically when a cabinet experiences an I/O channel fault or a fiber transceiver issue. A maintenance engineer told us they swapped a UAD card in under 30 minutes during a scheduled stop, which saved them a full production shift.

Advantages & Value

• Platform compatibility – Purpose‑built for ABB AC 800PEC, so integration effort is minimal.
• EMC resilience – Fiber‑optic links help avoid noise issues common around MV drives and converters.
• Service efficiency – Board‑level replacement typically keeps downtime and commissioning risk low.
• Lifecycle support – ABB’s global footprint makes sourcing and documentation straightforward for audits and spares planning.
• Total cost – Faster fault isolation and swap reduce engineering hours over the system’s life.

Installation & Maintenance

• Cabinet & environment – Install in an ABB AC 800PEC subrack within a closed control cabinet meeting IEC standards; allow clean airflow and keep ambient within 0…+55 °C.
• Power & wiring – Use a clean 24 VDC control supply. Route signal and fiber cables separately from power cables. Maintain bend radii for fibers and shield terminations for analog lines.
• ESD precautions – Handle the board with grounded wrist straps; avoid touching components and optical ports.
• Commissioning checks – Verify fiber link integrity, I/O mapping in the AC 800PEC application, and correct grounding scheme.
• Routine maintenance – Periodically inspect connectors, clean dust with dry air, check fiber ends, and update controller firmware/configuration as recommended by ABB.

Quality & Certifications

• Manufacturer quality systems typically aligned with ISO 9001.
• CE compliance and RoHS conformity for EU markets (board-level).
• UL recognition may apply at system level depending on cabinet and final assembly.
• Standard manufacturer warranty: 12 months from delivery (365 days).

If you’re aligning this board with an existing AC 800PEC controller, share the controller revision and application (drive type, gate unit family). It seems to be the quickest way to confirm option compatibility on the first pass and avoid rework during commissioning.
