GE GUVT240 Unit Voltage Acquisition Monitoring Module Detailed Explanation
1. Model Classification and Positioning
`GUVT240` belongs to the **GE (now Vernova) Mark VI/Mark VIe Turbine and Generator Control System Special Voltage Conditioning Acquisition Card**. GUVT is the exclusive voltage monitoring series name of GE. The 240 represents the ability to adapt to rated 240V AC voltage measurement points for acquisition, and it is the same as the wind power main control board `IS215WECAH1A` you previously queried. They both belong to the unit control hardware product line, mainly undertaking the tasks of generator terminal PT transformer voltage sampling and excitation circuit voltage feedback acquisition, and are compatible with thermal power / hydropower / gas turbine control cabinets.
