GE IS200AEADH1A

Product Introduction:

  • The GE IS200AEADH1A is an analog input/output interface board used in GE Speedtronic Mark VI and Mark VIe turbine control systems. It interfaces with terminal boards to accept and condition a variety of analog signals, including LVDT inputs, servo valve outputs, thermocouple inputs, 4–20 mA inputs and outputs, vibration inputs, and generator/line signals. It works in coordination with STCA and TCQC boards for signal routing and processing.
