IS200SCTLG1ABA is a Smart Contact Input/Output Terminal Board within the GE Mark VIe Speedtronic control system. It is a critical field-termination accessory designed specifically for GE heavy-duty gas and steam turbine applications. This board physically interfaces field-mounted dry-contact sensors—such as pressure switches, temperature switches, valve limit switches, and emergency stop pushbuttons—with the main Mark VIe VME-based controller processors. The “smart” designation comes from its onboard logic capabilities, which include programmable contact debouncing, change-of-state detection, and high-resolution hardware time-stamping, offloading real-time processing tasks from the main CPU to improve overall system determinism.
