The IS200WNPSH1A (and its more comprehensive version, the IS200WNPSH1AAA) is a core servo control board and power sub-board module manufactured by General Electric (GE) specifically for Mark VI/Mark VIe gas turbine and steam turbine control systems.
It connects the higher-level control network to the lower-level actuators, serving as the electrical and data communication interface between Industrial Ethernet (IONet) and the TSVO servo terminal board. Through its built-in WSVO servo drive core, the board can simultaneously manage two completely independent servo valve position loops, fine-tuning the opening of various valves controlling fuel and steam flow during generator operation to prevent overspeed or abnormal oscillations.
The IS200WNPSH1A IS200WNPSH1AAA GENERAL ELECTRIC Power Supply Daughter Card may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
AAA: Represents a specific backward-compatible artwork, version, and assembly configuration code. If you want to replace H1A, H1AAA can be directly replaced.
Due to the extremely high reliability requirements of turbine management, this daughterboard is directly integrated into the Mark VIe control loop, providing the following functions:
Open Circuit Detection: Continuously monitors the health of upstream vibration inputs to trigger early sensor fault alarms before turbine tripping.
Connector ID Authentication: Equipped with a hardware verification chip that scans cable connectors. This prevents engineers from inserting incorrect or mismatched I/O components into terminal assemblies.
Environmental Tolerance: Rated for continuous operation in harsh control cabinets at high temperatures (0 to 60 °C/32 to 140 °F).
