ABB 3BHE027632R0101 Arc‑Fault Detection Interface Board

Description

Hardware and Performance Specifications Auxiliary supply: 24 V DC, 18‑30 V DC wide‑range input Power consumption: ≤8 W Signal Inputs: Multi‑channel optical arc‑fault sensor receiving channels Response time: Fast arc‑fault detection and logic judgment Communication interfaces: AC800PEC rack internal high‑speed back‑plane bus Mounting mode: Subrack plug‑in PCB for UNITROL6000 excitation cabinet 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. 0.46 kg Certifications: CE approval

Main Functions Receive optical signal from arc‑fault sensors inside excitation cabinet. Complete signal identification, filtering and arc‑fault logic judgment. Trigger alarm and trip‑command output when arc‑fault event occurs, protect excitation power‑semiconductor devices and cabinet equipment. Transmit arc‑fault alarm, fault‑location information and status data to excitation main controller via internal back‑plane bus. Front‑panel LED indicators display power‑on status, channel link status and arc‑fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects optical‑channel failure, sensor abnormal and internal circuit faults, upload fault status to main unit. Parameter configuration, sensitivity setting and fault diagnosis are completed by ABB excitation engineering software.

Installation Requirement Plug‑in installation inside UNITROL6000 excitation subrack. High‑power power cables and weak‑signal optical‑fiber wiring shall be routed separately. Ensure reliable cabinet protective grounding. After board replacement, confirm full part‑number UFC921AE / 3BHE027632R0101 strictly matches original project configuration, download complete excitation‑configuration file. Perform optical‑channel test, arc‑fault sensor loop verification and back‑plane‑bus communication inspection. Different hardware revisions cannot be directly interchanged without firmware and configuration adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Arc‑fault‑detection interface 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 safety‑protection maintenance and spare‑part replacement.
