Weighing 3 lbs. 6 oz. (1.53 kg), this board is housed in an auxiliary cabinet and interfaces with the EMIO and EXTB control boards. Powered by a 24 VDC supply routed through the EXTB board, the IS200EDEXG1B manages SCR de-excitation and provides backup initiation if primary EXTB control fails, dispersing field energy safely through a field discharge inductor.\u003c\/p\u003e\n\u003ch2\u003ePart Number Breakdown\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIS200:\u003c\/strong\u003e GE Innovation Series \/ EX2100 System Board Architecture\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEDEX:\u003c\/strong\u003e De-Excitation Bridge and Protection Functional Designator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eG1:\u003c\/strong\u003e Group 1 Standard Board Configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eB:\u003c\/strong\u003e Revision B Hardware Version\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications Table\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin-top: 10px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"text-align: left;\"\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #ddd;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"padding: 8px; border: 1px solid #ddd;\"\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd; font-weight: bold;\"\u003eManufacturer \/ Brand\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eGeneral Electric (GE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd; font-weight: bold;\"\u003eFull Catalog Number\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd; font-weight: bold;\"\u003eIS200EDEXG1B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd; font-weight: bold;\"\u003eSystem Series \/ Application\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eInnovation Series \/ EX2100 Excitation Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd; font-weight: bold;\"\u003eBoard Weight\u003c\/td\u003e\n\u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e3 lbs. 6 oz.

Designed with double redundancy, the board initiates field de-excitation if the EXTB control signal fails. In SCR de-excitation mode, the SCR fires to create a conduction path through the field discharge inductor. If normal gate firing fails, an integrated break-over diode string triggers an overvoltage fire sequence when anode-to-gate voltage exceeds break-over thresholds, securing heavy generator field coils against catastrophic fault conditions.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions (FAQs)\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: What boards connect to IS200EDEXG1B?\u003c\/strong\u003e\u003cbr\u003eA1: It connects directly to the EMIO and EXTB control boards.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: How is the board powered?\u003c\/strong\u003e\u003cbr\u003eA2: It receives 24 VDC power through the EXTB board.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: How heavy is this board?\u003c\/strong\u003e\u003cbr\u003eA3: The unit weighs 3 lbs. 6 oz.
