Technical Specifications Multi‑channel exciter analog input and output interfaces, Mark V back‑plane bus connector, auxiliary DC power supplied by chassis back‑plane. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, relative humidity 5%‑95% non‑condensing. Conformal coating PCB anti‑corrosion protection. Mark V plug‑in mechanical structure.
Functional Features Collects generator exciter voltage and current analog feedback signals. Executes signal filtering and conditioning for exciter measurement signals. Receives excitation control set‑point commands from main CPU and converts into analog output signals for exciter power unit. Provides over‑range protection for analog channels. Supports exciter‑loop signal self‑diagnosis function.
Performance Parameters High‑precision exciter signal sampling performance, low analog output signal drift, stable excitation closed‑loop signal transmission characteristic.
Material Composition Multilayer glass‑fiber epoxy printed circuit board with ACB‑revision component layout. Analog signal conditioning and conversion components, over‑voltage protection devices. Gold‑plated Mark V back‑plane edge connector. Front metal panel with status LED indicators and fixing hardware. Conformal protective coating layer.
Structural Characteristics Standard Mark V chassis plug‑in board dimension. Rear gold‑plated edge connector mates with Mark V system back‑plane bus. Front metal panel includes status LED indicators and fixing screws. PCB layout separates exciter high‑amplitude signal area and low‑voltage logic area to suppress electromagnetic interference.
Working Principle Board obtains operating power from Mark V chassis back‑plane. Main CPU sends excitation adjustment commands, on‑board circuit converts digital commands into analog control signals to drive exciter power unit. Hardware circuit monitors analog channel abnormal status.
Installation Requirements Insert DS200TCEAG1ACB into assigned chassis slot, tighten front‑panel fixing screws. Restore chassis power supply, complete system power‑on self‑test and excitation control loop signal calibration verification.
Usage Notes Avoid mechanical scratch damage to conformal coating layer. Only apply within compatible GE Mark V turbine‑generator control chassis.
