Technical Specifications Multi‑channel digital signal termination interfaces, Mark V back‑plane bus connector, auxiliary DC operating power fed from chassis back‑plane. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, relative humidity 5%‑95% non‑condensing. Conformal coating PCB protection. Standard Mark V plug‑in form factor.
Functional Features Performs impedance termination for high‑speed digital drive signal lines. Buffers and reshapes digital control signals to reduce signal reflection and electromagnetic interference. Routes digital drive commands from main processor to downstream power drive modules. Provides hardware surge suppression for each signal channel. Supports power‑on channel status self‑diagnosis.
Performance Parameters Accurate signal impedance matching, stable digital signal reshaping performance, low signal distortion, reliable channel surge suppression capability.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Signal termination resistors, buffer integrated circuits, surge suppression components. 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 mounts status LED indicators and fixing screws. PCB layout separates high‑speed digital signal tracks from low‑speed auxiliary circuits to minimize crosstalk.
Working Principle The board receives operating power from Mark V chassis back‑plane. Digital drive control signals coming from main CPU board pass through on‑board termination network for impedance matching. On‑board monitoring circuit continuously checks signal channel integrity and reports abnormal status to system main processor.
Installation Requirements Insert DS200DDTBG1A into designated chassis slot and tighten front‑panel fixing screws. Restore chassis power supply, complete system power‑on self‑test and digital signal loop verification.
Usage Notes Avoid mechanical scratch damage to conformal coating layer. Only use within compatible GE Mark V turbine control chassis.
