Description
1. Product Title
GE IS200TRPAH2AHE – Turbine Primary Aeroderivative Protection Terminal Board
2. Product Overview
The IS200TRPAH2AHE is a specialized Turbine Primary Protection (TRPA) terminal board designed specifically for GE’s aeroderivative gas turbine control systems within the Mark VI and Mark VIe families. Its primary function is to serve as the critical interface for high-speed protective signals, including overspeed sensing and flame detection. Unlike standard heavy-duty turbine boards, theIS200TRPAH2AHE is tailored for the rapid response times and specific sensor types (such as high-frequency magnetic pickups) required by aeroderivative engines like the LM2500 or LM6000. It solves the industrial challenge of providing a fail-safe, hardware-based protection layer that can react to the high-velocity transients common in aviation-derived industrial power units.
