    • Combined-cycle power plants
    • Steam turbine power plants
    • Industrial turbine control and petrochemical drive systems
  • Installation Requirements
    • Install in Mark V / Mark VI dedicated VME cabinet
    • Use shielded twisted-pair cable for analog signals; shield grounded at single point
    • Maximum field wiring gauge: 14 AWG (2.08 mm²)
    • For redundant configuration, install in the same bus segment as the main control module
  • Usage Notes
    • Do not exceed analog input rated range to avoid ADC damage
    • 4–20 mA inputs must not be open-circuited
    • Relay outputs must not drive inductive loads above rated value
    • Calibrate periodically to maintain analog channel accuracy
    • Derate operation for altitudes above 1000 m
