Core Function

STAO simplex analog output terminal board for Mark VIe turbine control system. It serves as signal conversion and termination interface between STAOH I/O pack and field regulating actuators. It transfers analog control signals to valve positioners and auxiliary regulating devices, completes signal filtering and noise suppression. The on‑board ID chip supports automatic system identification and fault diagnosis. It applies to simplex turbine control configuration, ensures stable transmission of analog regulating signals for fuel valves and steam valves.

Product Details

The IS200STAOH2AAA is STAO series simplex analog output terminal board for GE Speedtronic Mark VIe turbine control system.

This termination board cooperates with STAOH I/O pack to realize analog signal output for turbine control loops. High‑density D‑Sub connector connects to upper‑level I/O pack, and field equipment is wired through European‑style screw terminal blocks. Built‑in noise filter circuit reduces electromagnetic interference from plant site, improves signal stability. The integrated ID chip allows control system to identify hardware model and execute online diagnosis, convenient for equipment status monitoring. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working conditions of power‑plant turbine cabinet. Widely used in simplex‑configured gas‑steam turbine control cabinets for analog regulating loop signal termination.

It belongs to important analog signal termination spare‑part for Mark VIe turbine control system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for analog signal loop debugging and defective IS200STAOH2AAA board replacement.
