Technical Specifications:
  • Logic: Microcontroller with EPROM config
  • Architecture: TMR channel sync
  • Outputs: Driver enable, alarm, status
  • Backplane: Mark IV digital slot
  • Temp: 0 °C to +60 °C
    Functional Features:​ Socketed EPROM for calibration data; abundant test points; DIP config; channel-health LED.
    Materials & Structure:​ 2-layer to 4-layer FR-4, plastic DIP sockets, metal oxide resistors.
    Working Principle:​ Microcontroller scans inputs, executes driver sequence, compares with other two TMR channels, enables output only on 2/3 agreement.
    Installation Requirements:​ Insert in Mark IV driver slot; keep EPROM handle locked; verify DIP matches machine S/N.
    Precautions:​ UV erases EPROM—never expose to sunlight; do not swap EPROM across different turbine units.
