Technical Specifications Multi‑channel analog signal input, isolated signal output to back‑plane bus. Auxiliary power supplied by excitation rack, typical power consumption 7.0 W. Operating temperature ‑10 ℃ to +55 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated circuit board, signal isolation voltage 2000 V AC.
Functional Features Collects generator‑side voltage and current analog feedback signals. Completes signal conditioning and galvanic isolation. Transmits processed feedback data to main regulator via back‑plane bus. On‑board LED reflects signal‑channel status. Built‑in hardware self‑diagnosis for signal‑loop faults.
Application Scenarios Internal spare‑part for UNITROL series generator excitation systems. Applied for power‑plant excitation‑equipment maintenance and spare‑part replacement.
Performance Parameters High‑fidelity signal conditioning guarantees feedback‑signal precision. Galvanic isolation blocks high‑voltage interference from generator‑side loops. Self‑diagnosis detects signal‑loop breakage and board‑level faults.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Analog signal conditioning components, optocoupler isolation assemblies. Conformal protective coating. Back‑plane plug‑in connectors and field‑signal input terminals.
Structural Characteristics Plug‑in circuit board matching excitation cabinet rack slot. Board edge fitted with back‑plane bus connector and analog‑signal input terminals. Reserved mechanical fixing holes. Weight approximately 0.67 kilogram.
Working Principle After power‑on, board completes hardware self‑check. Generator‑side feedback analog signals enter through field‑input terminals. Signals go through conditioning and galvanic‑isolation processing. Valid feedback data is transmitted to excitation main regulator via back‑plane bus. Diagnosis circuit monitors each signal‑channel operating state in real‑time.
Installation Requirements Cut off all power sources of excitation cabinet before replacement. Insert XVC768AE101 3BHB007211R102 into corresponding slot and tighten fixing screws. Confirm back‑plane connector is fully locked. Restore power supply and calibrate analog‑signal sampling accuracy.
Usage Notes Adopt anti‑static wrist strap during disassembly‑assembly. Do not scratch conformal coating surface. Hot‑plug under powered state is strictly forbidden. Complete feedback‑signal calibration after spare‑part installation.
