Products Description
GE IS200STAOH2AAA Analog Output Terminal Board in stock
GE IS200STAOH2AAA is a simplex STAO analog output terminal board for GE Speedtronic Mark VIe turbine control system. It is matched with PAOC analog output I/O pack, providing 8 channels of 0-20mA analog output signals to drive fuel valves, inlet guide vane actuators and bypass valves for gas and steam turbines.

This terminal board adopts Euro-block terminal design, built-in signal filtering and surge suppression circuit. The onboard ID chip supports automatic identification and system self-diagnosis. It is widely used in combined cycle power plant turbine regulation control loops, and serves as a common spare part for Mark VIe cabinet maintenance and renovation.
