Description
The GE IS200TTURH1C is a Turbine Terminal Board designed for GE Speedtronic Mark VI / Mark VIe turbine control systems. It provides the terminal interface between field turbine protection devices, speed sensing equipment, generator signals, and GE turbine I/O control modules.
The TTURH1C board is used with PTUR and VTUR turbine control boards to support turbine protection, synchronization, speed monitoring, and trip-related functions. It handles signals from pulse rate devices, generator voltage inputs, bus voltage inputs, shaft voltage/current monitoring, and breaker-related control circuits.
The IS200TTURH1C supports Simplex and TMR (Triple Modular Redundant) Mark VIe configurations, providing reliable signal termination and connection between field wiring and turbine control I/O packs.
