Product function

Governor Signal Generation: Digitally controlled analog outputs deliver precise speed/load setpoints through the GE IS200DAMEG1A to engine-governor valves.

Status Monitoring: Discrete inputs capture critical governor-system statuses such as overspeed trips, mode selects, and manual overrides.

Diagnostics: On-board detection of loop faults (open, short) and discrete-input errors, reported back to the Mark VIe CPU for alarms and safe-state actions.

Core supporting modules

I/O Pack Carrier: IS42xPSCAH1B supplying 24 V DC power and IONet backplane connectivity

Controller Module: IS200TPROH1C Mark VIe CPU executing governor algorithms and safety interlocks
