ABB UAD206A101 (3BHE019958R0101) – Mixed I/O Interface Board for ABB Industrial Control and Excitation Systems

• Warranty: 365 days

• Lead time: 1 week if in stock; no more than one month at the latest

• Payment: 50% advance payment; full payment before delivery

• Express options: FedEx, UPS, DHL

• Mixed-signal I/O front-end: Handles both analog measurement and digital status/control signals for ABB control systems.

• Backplane communication: Connects to the host controller via ABB’s backplane bus; no field wiring directly to Ethernet ports, which keeps noise down in many cases.

• Industrial-grade design: Built for 24/7 environments; conformal coating variants are typically available for harsh conditions.

• Service-friendly layout: Plug-in replacement with guided connectors—maintenance teams usually swap it in minutes when the cabinet is prepared.

• Signal conditioning onboard: Isolation and filtering stages (as applicable) help stabilize readings in noisy motor rooms.

• Diagnostics indicators: Status LEDs (where present) speed up commissioning and fault tracing.

• Compatibility-first approach: Commonly applied with ABB AC 800PEC and UNITROL platforms to maintain system-level compatibility and lifecycle continuity.

This board shows up in power electronics controls where fast, deterministic I/O is needed. Typical environments include:

• AC/DC drive cabinets (steel and paper lines, mining conveyors, marine propulsion)

• UNITROL-based generator excitation and power plant auxiliaries

• Wind and test-bench converters using AC 800PEC control

• High-performance motion or rolling mill stands where robust noise immunity is essential

A maintenance lead from a paper mill told me they swapped a UAD206A101 in under 20 minutes during a night shift—no software changes, just careful ESD handling—and the drive line was back at speed before the next reel change. That’s typically the kind of low-drama service event plants want.

• Reliability: ABB boards like this are built for continuous operation and stable signal integrity.

• Compatibility: Designed to work within ABB control ecosystems (AC 800PEC / UNITROL), reducing integration risk.

• Lifecycle support: Keeps legacy and current cabinets serviceable—cost savings versus wholesale redesign.

• Maintenance speed: Plug-in architecture shortens MTTR, which in many cases saves far more in downtime costs than the part itself.

• Quality traceability: Clear part coding (3BHE019958R0101) supports documentation and spare part management.

• Cabinet conditions: Install in a clean, ventilated enclosure; maintain airflow paths and avoid heat sources directly beneath the board.

• Grounding & shielding: Bond cabinet PE properly; route shielded signal cables with single-point grounding to minimize noise.

• Backplane integrity: Inspect card guides and connectors; reseat with even pressure and secure retention screws.

• ESD handling: Use wrist straps and antistatic packaging; avoid touching component pins or analog front-end areas.

• Routine checks: Quarterly visual inspection for dust, discoloration, or loose connectors; clean with dry air per site policy.

• Firmware/config: If the application uses controller-resident firmware parameters, back up settings before replacement; restore and verify I/O scaling after swap.

• CE marking: Conforms as part of the complete ABB system

• ISO 9001 manufacturing: Produced under ABB’s quality management system

• RoHS: Typically compliant for standard variants

• Warranty: 365 days (exchange/repair per inspection)

• ABB AC 800PEC controller and carrier backplane (host CPU and rack)

• UNITROL excitation platform components (for generator applications)

• Shielded cable sets and terminal adapters for analog/digital field wiring

• Filtered 24 VDC power supply modules and EMC cabinet accessories

Note: Channel counts and exact I/O mapping can vary by system configuration and board revision. If you share your cabinet type and controller setup, I can match the UAD206A101 to the correct backplane slot and provide a wiring/commissioning checklist.
