ABB UFC760BE1142 (3BHE004573R1142) – Central Controller Board for UNITROL 5000 Excitation Systems

• Warranty: 365 days

• Delivery: 1 week for in-stock; no more than one month at the latest

• Payment: 50% advance payment, full payment for delivery

• Express Options: fedex, UPS, DHL

• Packaging: ESD-safe, foam-in-box, moisture barrier where required

• Traceability: Serial and revision recorded on the delivery note

• Purpose-built for UNITROL 5000: Works as the central control board coordinating excitation control, protection, and diagnostics.

• Deterministic control performance: Real-time control platform designed for fast voltage and reactive power response under grid disturbances.

• Backplane integration: Plugs directly into the UNITROL rack backplane for power, I/O bus and inter-board signaling—no field rewiring.

• Multiple communication paths: Typically supports Ethernet service access and fieldbuses (e.g., CAN) to I/O and peripheral boards.

• Event and fault diagnostics: Detailed status LEDs and onboard diagnostics simplify commissioning and troubleshooting.

• Service-friendly replacement: Front-access connectors and keyed guides make swap-outs straightforward during outages.

You’ll typically find this board in power generation (hydro, steam, gas) and in heavy industry where synchronous motors need robust excitation—steel mills, paper, cement, mining, and oil & gas utilities. It’s also a common spare at plant maintenance stores because a healthy controller board can bring a trip-latched exciter back within minutes once wiring and settings are verified.

• Reduced downtime: Drop-in replacement in the UNITROL rack, speeding up restoration during outages.

• Compatibility: Designed for the UNITROL 5000 platform with typical backward compatibility across board revisions.

• Procurement certainty: Clear part number mapping (UFC760BE1142 / 3BHE004573R1142) minimizes mismatches.

• Lifecycle support: Access to service Ethernet and standard buses simplifies remote diagnostics and parameter management.

• Cost control: Stocking a tested controller board as a strategic spare often saves forced-outage penalties in many cases.

• Cabinet requirements: Install in a clean, well-ventilated UNITROL 5000 cabinet. Keep ambient within 0…55 °C and avoid condensation.

• ESD handling: Use grounded wrist straps and ESD mats. Avoid touching component surfaces and connector pins.

• Wiring & seating: Power and signals are via backplane; ensure the card is fully seated in guides and locking screws are secured.

• Firmware & parameters: Back up parameters before replacement. After swapping, load the saved configuration and verify setpoints.

• Routine checks: Inspect connectors quarterly, clean dust with dry air, and check event logs for recurring alarms.

• Service access: Use the service Ethernet/maintenance port for diagnostics and commissioning where available.

• CE-marked industrial control component

• RoHS-compliant materials

• Manufactured under ISO 9001 quality systems

• Standard warranty: 365 days

Typical companions in a UNITROL 5000 rack include UFD-series I/O boards and power interface/firing modules. If you’re refreshing spares, consider pairing the UFC760BE1142 with one digital I/O board and a compatible power interface to cover the most common failure points.
