Technical Specifications Module Type: Rack internal power‑rail monitoring board Applicable System: GE Mark VI Turbine Control System Monitored Object: Multiple internal rack power supply rails Backplane Interface: Mark VI internal backplane bus Operating Power: Derived from rack internal monitored power rails Operating Temperature: ‑30 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard Mark VI plug‑in PCB board Certifications: CE, UL power generation industrial component compliance
Functional Features Real‑time sampling and monitoring of multiple internal power supply voltage rails inside control rack. Detects under‑voltage, over‑voltage and power rail abnormality conditions. Transmits power‑supply status and fault alarm information to main controller via backplane bus. Front‑edge LED indicators reflect power‑rail health status. Built‑in hardware self‑diagnosis for board internal circuit failure detection. Provides power‑fault early warning reference for turbine control system logic.
Application Scenarios Internal power health monitoring for Mark VI turbine control cabinet. Power‑supply fault detection for gas‑turbine and steam‑turbine control hardware. Spare‑part replacement for legacy Mark VI power‑plant control systems.
Structural Characteristics Standard plug‑in PCB structure compatible with Mark VI rack slots. Front‑edge LED status indicator group for power‑rail condition display. Rear golden‑finger connector connects to rack backplane for power tapping and data communication.
Working Principle The board taps voltage signals from different internal power rails via backplane golden‑finger contacts. On‑board sampling circuits measure each rail voltage value continuously.
Installation Requirements Install board into designated monitoring slot of Mark VI control rack. Complete rack protective grounding complying with GE power‑plant grounding specification. Confirm backplane slot contacts are clean and free of debris before insertion. Ambient cabinet temperature and humidity shall stay within rated range without condensation.
