Product Introduction
The GE IS200PAICH1B is a high-performance Turbine Protection Board designed for use within the GE Mark VI and Mark VIe series of turbine control systems. Specifically engineered to manage analog signal acquisition and conditioning, this board plays a critical role in monitoring turbine operating parameters such as pressure, vibration, and temperature, feeding these inputs directly into the control system’s logic processors for real-time protection and control actions.
This board is a key component of GE’s integrated control and protection architecture, offering precision input handling for analog signals in demanding industrial environments. The IS200PAICH1B interfaces seamlessly with input terminal boards such as STAI or TBTH, filtering, scaling, and isolating analog signals before delivering them to the controller through the IONet communication bus.
It is typically used in steam, gas, and hydro turbine systems, ensuring timely fault detection and safe shutdown capabilities, contributing to asset reliability and operational safety.
