The IS210AEAAH2B is an I/O board from the AE (Acquisition & Excitation) series, designed for the GE Speedtronic Mark VIe control system. It functions as a distributed signal interface board based on a VME architecture and features onboard DSP (Digital Signal Processor) capabilities. It is primarily used in gas turbines, steam turbines, and wind turbine generator sets for the closed-loop control of excitation and process signals. The board supports the acquisition of various field signals—such as 4–20 mA, ±10 V, RTD (resistance temperature detector), and thermocouple inputs—providing high-precision sampling for monitoring parameters like terminal voltage, excitation current, temperature, pressure, and vibration. It supplies excitation power to passive sensors while simultaneously processing feedback and control outputs for the excitation system; in conjunction with the EX2100 excitation system, it facilitates the regulation and control of generator voltage and reactive power.
