Description

Hardware and Performance Specifications Auxiliary supply: 24 V DC, 18‑30 V DC wide‑range input Power consumption: ≤14 W Processor: High‑reliability real‑time industrial co‑processor, expanded Flash and RAM memory Programming: Support ABB DPL drive programming language for custom application blocks Communication interfaces: Internal AC800PEC high‑speed back‑plane bus Mounting mode: Subrack plug‑in PCB for UNITROL6000 excitation rack Protection class: IP20 Operating temperature: ‑25 ℃ ~ +70 ℃ Storage temperature: ‑40 ℃ ~ +85 ℃ Humidity: 5‑95 %RH non‑condensing EMC compliance: Comply with IEC 61000‑4 series industrial electromagnetic‑compatibility standards Dimension & weight: approx. 240 × 160 × 35 mm, weight approx. 0.58 kg Certifications: CE approval

Main Functions Provide extended real‑time computing resource for UNITROL6000 excitation control system. Execute user‑defined custom application logic, advanced auxiliary control algorithms and data recording tasks. Realize large‑capacity event and disturbance‑waveform data buffer storage. Coordinate data interaction between main controller and external communication peripherals. Front‑panel LED indicators display power‑on status, running status and hardware‑fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects memory fault, bus communication abnormality and internal circuit failure, upload fault‑alarm information to main control unit. Parameter configuration, custom‑program download and diagnosis are completed by ABB excitation engineering software.

Installation Requirement Plug‑in installation inside UNITROL6000 excitation subrack. High‑power power cables and weak‑signal measuring cables shall be routed separately. Ensure reliable cabinet protective grounding. Auxiliary 24 V DC power supply shall stay within rated operating range. After board replacement, confirm full part‑number UFC789AE101 / 3BHE014023R0101 strictly matches original project configuration, download complete excitation configuration and custom application program. Perform back‑plane‑bus communication test and logic‑function verification. Different hardware revisions cannot be directly interchanged without firmware and program adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Extended co‑processor spare‑part for UNITROL6000 static excitation‑systems of large‑capacity synchronous generators in thermal‑power plants, hydropower plants and heavy‑industrial captive‑power‑stations; used for excitation‑system maintenance and spare‑part replacement.

Key Features

1. Dedicated high‑performance co‑processor board for AC800PEC‑based UNITROL6000 excitation platform, provides extra computing resources for complex custom control logics.
2. Support DPL user programming, flexible for site‑specific special‑function expansion.
3. Plug‑in subrack‑mount structure, convenient for on‑site replacement and maintenance.
4. Complete hardware self‑diagnosis function for fast fault location.
5. Strict full‑part‑number matching shall be observed during spare‑part replacement; cannot be substituted by ordinary UFC series boards without firmware and program download.
