Technical Specifications Multi‑channel DC signal input 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 chassis plug‑in board form.
Functional Features Receives multi‑group DC analog feedback signals from field transducers and power units. Executes signal filtering and amplitude conditioning for input DC signals. Forwards conditioned sampling data to main CPU board via Mark V back‑plane bus. Provides hardware over‑voltage protection for each input channel. Supports channel‑level self‑diagnosis function.
Application Scenarios Spare replacement DC feedback board for GE Mark V gas and steam turbine control systems, used for power‑plant turbine‑control‑system overhaul and maintenance work.
Performance Parameters High‑precision DC signal sampling accuracy, low signal drift, good noise‑filtering performance, reliable channel fault‑detection response.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. DC signal conditioning and filter components, over‑voltage protection devices. Gold‑plated Mark V back‑plane edge connector. Front‑panel metal bracket with status LED indicators. Conformal protective coating layer.
Structural Characteristics Standard Mark V plug‑in board dimension. Rear gold‑plated edge connector mates with Mark V chassis back‑plane bus. Front metal panel includes status LED indicators and fixing screws. PCB layout separates DC analog‑signal region and digital‑bus logic region for interference suppression.
Working Principle Board obtains operating power from Mark V chassis back‑plane. External DC feedback signals enter input terminals, pass through filter and conditioning circuit to adjust signal amplitude. Hardware circuit monitors input‑channel abnormal status.
Installation RequirementsInsert DS200DCFBG1B board into corresponding chassis slot, tighten front‑panel fixing screws. Restore chassis power supply, complete system power‑on self‑test and DC‑signal channel calibration verification.
Usage Notes Avoid mechanical scratch damage to conformal coating. Only apply within compatible GE Mark V turbine control chassis.
