Description
Overview
The IS200VTURH1BAA Turbine Protection Card is a dedicated trip and monitoring module developed by General Electric for the Mark VI/Mark VIe turbine control platform. Engineered to support both gas and steam turbine applications, this board provides high‑precision overspeed protection, flame detection processing, and shaft‑voltage monitoring within critical safety loops.
Functional Characteristics
This protection card manages multiple turbine‑specific safety functions. It processes signals from passive magnetic speed pickups across a wide frequency range and supports high‑accuracy overspeed detection. The module also interfaces with flame detection devices and shaft‑current sensors, enabling comprehensive turbine condition monitoring.
In redundant TMR architectures, the IS200VTURH1BAA operates nine magnetic relays to ensure fault‑tolerant trip execution. Simplex systems utilize three relays, maintaining reliable trip capability while reducing hardware complexity. The board also supports synchronization and breaker‑control functions when paired with compatible terminal boards.
