Speed Interface Control Board GE DS200HSTIG1AAA Digital I/O Extension Unit Dimensions: 90 × 120 ×Overview The GE DS200HSTIG1AAA, also known as the High Speed Trip Interface Board (HSTI), is a critical component of the GE Mark V SPEEDTRONIC turbine control system. Its primary function is to process high speed trip signals from turbine speed sensors, ensuring rapid detection of overspeed conditions. This capability is essential for the protection of gas and steam turbines, safeguarding the turbine from damage by triggering immediate shutdowns
