    GE IS200TBCIH1BBC Contact Input Terminal Board
    Manufacturer: GE / Baker Hughes
    Model: IS200TBCIH1BBC
    Series: Mark VI / VIe Speedtronic Turbine Control
    Type: Contact Input Terminal Board
    Function: Dry contact signal acquisition, group isolation, and noise suppression for turbine safety & interlock logic
    1. Overview
    The GE IS200TBCIH1BBC is a **high-density contact input terminal board** for the Mark VI/VIe turbine control system. It interfaces field dry contacts (limit switches, relay contacts, pushbuttons) to the controller, providing 24 isolated input channels for safety interlocks, trip logic, and auxiliary device status monitoring in power generation plants.
