Description
1. Product Title
GE IS200WREAS1ADB – Wheel Radio Equipment Assembly Board
2. Product Overview
TheIS200WREAS1ADB is a specialized communication interface board within the GE Mark VI and Mark VIe control families, specifically designed for “Wheel Radio” applications. Its primary function is to facilitate wireless data transmission between the rotating components of a turbine (the wheel/rotor) and the stationary control system. TheIS200WREAS1ADB is essential for monitoring critical rotor-side parameters—such as strain, temperature, and vibration—without the need for physical slip rings, which are prone to wear and electrical noise. This module solves the complex industrial challenge of acquiring high-fidelity telemetry from high-speed rotating shafts, enabling real-time condition monitoring and preventing catastrophic mechanical failure through early detection of rotor stress.
