It serves as an analog measurement input board, receiving high-voltage and high-current AC feedback signals from power generator potential and current transformers, scaling them to low-level control voltages, and delivering conditioned feedback to the primary turbine and exciter control loops. The board is designed as a normal assembly without a metallic VME rack faceplate, relying on direct cabinet panel or frame mounting within the exciter control assembly.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eIS200EPCTG1AAA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric (GE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eSystem backplane \/ bus powered\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMark VI Speedtronic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eExciter PT\/CT Board (EPCT)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctional Revision Level\u003c\/td\u003e\n\u003ctd\u003e3 revisions (2 functional, 1 artwork revision)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackwards Compatibility\u003c\/td\u003e\n\u003ctd\u003eCompatible across the first two functional revisions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssembly Type\u003c\/td\u003e\n\u003ctd\u003eNormal Assembly (no VME metallic faceplate)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Inputs\u003c\/td\u003e\n\u003ctd\u003ePotential Transformer (PT) \u0026amp; Current Transformer (CT) feeds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFirmware Flash Compatibility and Signal Scaling\u003c\/h3\u003e\n\u003cp\u003eThe IS200EPCTG1AAA maintains strict backward compatibility across functional revision levels to ensure seamless integration with active GE Toolbox firmware flash structures. The board scales raw high-magnitude AC PT and CT secondary outputs down to low-voltage analog inputs processed directly by the central controller. Maintaining precise attenuation ratios and low phase-shift characteristics allows the Mark VI system to execute real-time power regulation, generator synchronizing, and overcurrent protection functions without signal propagation delays.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the IS200EPCTG1AAA board be mounted directly into a standard VME card rack?\u003c\/p\u003e\n\u003cp\u003eA: No. The IS200EPCTG1AAA is a normal assembly board that lacks a metallic VME installation faceplate, requiring direct mounting within the designated control cabinet frame or backplane interface assembly.\u003c\/p\u003e\n\u003cp\u003eQ: How are the three revision levels of the IS200EPCTG1AAA structured?\u003c\/p\u003e\n\u003cp\u003eA: The board includes two functional hardware revisions and one artwork configuration revision.
