Description

Hardware and Performance Specifications Auxiliary supply: 24 V DC, 18‑36 V DC wide‑range input Power consumption: ≤5 W Analog channels: Multi‑channel galvanic‑isolated analog input; 16‑bit high‑resolution ADC Isolation voltage: 2500 V AC reinforced isolation Accuracy: ±0.5 % full‑scale Communication interfaces: AC800PEC subrack internal back‑plane bus Mounting mode: Subrack plug‑in card for AC800PEC 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: 160 × 105 × 50 mm, weight approx. 0.4 kg Certifications: CE approval

Main Functions Realize galvanic isolation and anti‑interference filtering for generator voltage, stator current and rotor field‑winding measuring signals. Complete high‑precision analog‑digital conversion of excitation‑system analog measuring quantities, upload sampling data to excitation main‑controller through back‑plane bus. Process analog signal feedback and conversion for power‑bridge monitoring loops. Built‑in hardware self‑diagnosis function, detect measuring‑loop abnormality and internal circuit fault, upload fault information to upper‑level controller. Front‑panel LED indicators display power‑on status and fault alarm codes for quick on‑site troubleshooting. Parameter configuration and debugging are completed by ABB excitation engineering software.

Installation Requirement Plug‑in installation inside AC800PEC subrack of UNITROL excitation cabinet. 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 module replacement, confirm full part‑number UUD148AE01 3BHE014185R0001 strictly matches original project configuration, download complete excitation configuration file. Perform analog‑channel calibration and back‑plane bus communication inspection. This module cannot run independently and must match supporting excitation main‑controller. Different suffix variants of UUD148 series cannot be directly interchanged without software adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios High‑speed signal‑conditioning transducer module for UNITROL5000 / UNITROL6000 large‑capacity static excitation‑systems of synchronous generators in thermal‑power plants, hydropower plants and large industrial captive‑power‑stations; used for excitation‑system maintenance and spare‑part replacement.

Key Features

1. Special high‑precision signal‑conditioning module for AC800PEC‑based excitation platform, 2500 V AC reinforced isolation effectively suppresses strong electromagnetic interference from power‑plant field environment.
2. 16‑bit high‑resolution ADC ensures high‑accuracy measurement for generator VT/CT and rotor field‑winding signals.
3. Subrack plug‑in card design, convenient for on‑site replacement and maintenance.
4. Built‑in channel self‑diagnosis function, easy for fault location.
5. Critical spare‑part for ABB large‑unit UNITROL excitation‑systems; full part‑number matching must be strictly observed during replacement.
