Technical Specifications Multi‑channel transducer signal input terminals, Mark V back‑plane bus interface, 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 anti‑corrosion PCB treatment. Mark V plug‑in mechanical form.
Functional Features Acquires multi‑group analog measurement signals from field transducers and sensors. Completes signal filtering, amplitude adjustment and level matching work. Converts conditioned analog signals into data format compatible with Mark V internal bus. Transmits sampling data to main CPU board. Provides hardware over‑voltage and transient surge protection for each input channel. Supports channel‑level fault self‑diagnosis.
Performance Parameters High‑precision analog signal conditioning accuracy, low signal drift, excellent noise filtering performance, stable multi‑channel data transmission capability.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Analog signal conditioning chips, filter components, surge protection devices. Gold‑plated Mark V back‑plane edge connector. Front metal panel equipped with status LED indicators and fixing screws. Conformal protective coating layer.
Structural Characteristics Standard Mark V plug‑in board dimension. Rear gold‑plated edge connector connects to Mark V chassis back‑plane bus. Front metal panel includes status LED indicators and fastening hardware. PCB layout implements physical separation between analog signal area and digital logic area to reduce electromagnetic crosstalk.
Working Principle Board draws operating power from Mark V chassis back‑plane. Raw transducer input signals enter board terminals and go through filter and conditioning circuit. On‑board hardware monitors input channel abnormal status and reports fault information to system.
Installation Requirements Insert DS200ITXDG1ABA into corresponding chassis slot, tighten front‑panel fixing screws. Restore chassis power supply, run system power‑on self‑test and complete transducer signal loop calibration and verification.
Usage Notes Prevent scratch damage to conformal coating protective layer. Only install into compatible GE Mark V turbine control chassis.
