General Electric IS200VTURH1BAA MK6 Gas Tmr Pk Turbine Card

Overview

The General Electric IS200VTURH1BAA MK6 Gas TMR PK Turbine Card supports Mark VIe turbine control systems with precise overspeed protection, flame detection, and shaft‑voltage monitoring. This board strengthens gas and steam turbine safety through fast trip response and accurate pulse‑rate processing. Its rugged construction ensures stable operation in demanding power‑generation environments.

Functional Design

The GE IS200VTURH1BAA manages three overspeed trip relays in simplex systems and nine magnetic relays in TMR architectures. It processes signals from four passive pulse‑rate devices across a 2 Hz–20 kHz range with 0.05% accuracy, enabling precise turbine speed monitoring. The board also supports eight Geiger‑Mueller flame detectors used in gas turbine applications.

The IS200VTURH1BAA integrates with TRPG terminal boards to activate emergency solenoids and supports automatic generator synchronization and breaker control. Its front panel includes RUN, FAIL, and STATUS LEDs, along with a D‑shell connector for system interfacing. The board detects speeds as low as 2 RPM with a 27 mV sensitivity threshold, ensuring reliable low‑speed monitoring.
