Technical Specifications Multi‑channel analog and digital signal interfaces, Mark V internal back‑plane bus connector, auxiliary DC control power supply. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, relative humidity 5%‑95% non‑condensing. Conformal coating PCB protection. Mark V chassis plug‑in board form.
Functional Features Acquires analog and digital feedback signals from turbine field‑side equipment. Processes control logic commands from main CPU board. Distributes driving control signals to related functional modules inside control system. Transmits status and fault feedback data back to main processor. Supports hardware channel self‑diagnosis function after power‑on.
Application Scenarios Original spare replacement board for GE Mark V gas / steam turbine control systems, used for power‑plant turbine control equipment maintenance and overhaul projects.
Performance Parameters High‑precision signal sampling and conditioning accuracy, stable internal bus data transmission, reliable channel fault‑diagnosis response capability.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Mixed analog‑digital signal processing components, logic integrated circuits. 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 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 partitions analog‑signal zone and digital‑logic zone for noise reduction.
Working Principle Board obtains auxiliary operating power from Mark V chassis back‑plane. Field feedback signals enter board and go through signal conditioning circuit. On‑board circuit monitors channel status and reports fault information to system.
Installation Requirements Insert DS200CDBAG1ABA board into assigned chassis slot, tighten front‑panel fixing screws. Restore chassis power supply, complete system power‑on self‑test and signal‑loop verification test.
Usage Notes Prevent scratch damage to PCB conformal coating layer. Only apply inside compatible GE Mark V control chassis.
