GE IS200STURH2AEC Spare Part | Mark VIe Turbine Overspeed Protection Terminal Board

Description

Product Overview

GE IS200STURH2AEC is a simplex primary turbine protection input terminal board for GE Mark VIe Speedtronic turbine control system. It accepts MPU magnetic pickup pulse speed signals, offering four independent pulse speed inputs, two safety trip relay outputs and two synchronization relays for turbine overspeed protection, unit trip interlock and generator synchronizing signal processing. Equipped with 48‑position euro‑style terminals, DC‑62‑pin connector for PTUR I/O pack connection and DC‑37‑pin connector for trip relays. This hardware is OEM obsolete. New surplus stock and fully‑tested refurbished spare parts are available for direct drop‑in replacement and maintenance of legacy gas & steam turbine protection circuits。
