This module serves as a central switching and signal routing interface within the excitation system's control architecture. Its primary function is to manage the selection logic between redundant control paths, ensuring that the system can seamlessly transition between active and standby controllers without disrupting the generator's field current. As a critical node in the EX2100 suite, the IS200ESELH3A facilitates communication between the main control processors and the bridge interface hardware, maintaining the high-availability standards required for utility-scale power generation.\u003c\/p\u003e\n\u003ch3\u003eKey Technical Characteristics and Hardware Parameters\u003c\/h3\u003e\n\u003cp\u003eThe IS200ESELH3A is engineered for longevity and precise signal execution, featuring a robust vertical form factor designed for standard EX2100 cabinet integration.\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eGeneral Electric (GE Industrial Systems)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eModel Number\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIS200ESELH3A\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Revision\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIS200ESELH3AAA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Series\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEX2100 Excitation Controller\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eModule Function\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eExciter Selector and Signal Routing\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eBoard Classification\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHigh-integrity Control Board\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLogic Redundancy\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDesigned for dual or triple modular redundant (TMR) excitation schemes\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMechanical Profile\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e33.02 cm High x 10.16 cm Wide\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Weight\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e2.72 kg (Approx. 6 lbs)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCountry of Manufacture\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUnited States of America (USA)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMounting Architecture\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDesigned for vertical rack slot installation within GE cabinet enclosures\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIndustrial Applications and Operational Use Cases\u003c\/h3\u003e\n\u003cp\u003eThis selector board is a cornerstone component in the management of synchronous generator excitation in demanding industrial sectors.\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRedundant Control Switching\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eManaging the \"Handover\" logic in dual-controller excitation systems to prevent generator trips during a single controller failure.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSignal Path Management\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRouting feedback and command signals between the digital controller cores and the Silicon Controlled Rectifier (SCR) firing circuits.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eUtility Power Stations\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEmployed in thermal and hydroelectric facilities where the EX2100 system must maintain absolute field current stability for grid compliance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSystem Diagnostics and Interfacing\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eProviding the physical interface for monitoring selector status, allowing plant operators to verify which control path is currently active.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMission-Critical Protection\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrating into the system-wide safety logic to ensure that selector commands are synchronized with de-excitation and breaker sequences.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":45643008442541,"sku":"IS200ESELH3AAA","price":469.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/IS200ESELH3A-11.jpg?v=1769048301","url":"https:\/\/www.maxwellplc.com\/products\/ge-is200eselh3a-exciter-selector-board-ex2100-series-is200eselh3aaa-control-board","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
