This module functions as a critical bridge and protection component, driving the electrical center for field windings with a low-frequency AC voltage relative to ground. It is primarily deployed in large-scale power generation and heavy industrial excitation systems to detect field ground leakage currents. By working in conjunction with the EGDM module, the IS200EXAMG1A enables precise identification of insulation breakdown, facilitating proactive maintenance and reducing the risk of generator failure.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSupports high-reliability redundant configurations with M1 and M2 controller switching.\u003c\/li\u003e\n\u003cli\u003eIntegrated precision sense resistor for field ground leakage detection.\u003c\/li\u003e\n\u003cli\u003eHardware-level configuration via three onboard jumpers (JP1, JP2, JP3).\u003c\/li\u003e\n\u003cli\u003eRobust connectivity including high-current stab-on connectors for Vbus-p (E1) and Vbus-n (E2).\u003c\/li\u003e\n\u003cli\u003eDesigned for integration within the EX2100 auxiliary cabinet architecture.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLarge-scale power generation excitation control.\u003c\/li\u003e\n\u003cli\u003eGas turbine control systems.\u003c\/li\u003e\n\u003cli\u003eGenerator field ground fault monitoring and protection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eIS200EXAMG1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eEX2100 Excitation Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoard Type\u003c\/td\u003e\n\u003ctd\u003eExciter Attenuator Module (EXAM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to 85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity\u003c\/td\u003e\n\u003ctd\u003e5 to 95% RH (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManual References\u003c\/td\u003e\n\u003ctd\u003eGEI-100509 \/ GEH-6632\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the system is fully de-energized before installing or removing the module.\u003c\/li\u003e\n\u003cli\u003eHandle the module using proper ESD (Electrostatic Discharge) mitigation techniques to prevent damage to sensitive internal circuitry.\u003c\/li\u003e\n\u003cli\u003eVerify that all cable connections, including the 9-position ground detector cable and high-current stab-on connectors (E1\/E2), are securely seated.\u003c\/li\u003e\n\u003cli\u003eConfigure jumpers JP1, JP2, and JP3 according to the specific site requirements defined in the GEI-100509 manual.\u003c\/li\u003e\n\u003cli\u003eEnsure the module is installed in an environment compliant with the specified temperature and humidity ranges to prevent premature component degradation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the IS200EXAMG1A?\u003c\/h3\u003e\u003cp\u003eThe IS200EXAMG1A acts as an attenuator and bridge module that injects a low-frequency AC voltage into the generator field winding to detect insulation degradation or ground leakage currents in the EX2100 system.\u003c\/p\u003e\u003ch3\u003eDoes this module support redundant control systems?\u003c\/h3\u003e\u003cp\u003eYes, the IS200EXAMG1A is designed to support redundant M1 and M2 controller configurations, allowing for seamless test signal processing.\u003c\/p\u003e","brand":"GE FANUC","offers":[{"title":"Default Title","offer_id":50642558877948,"sku":"IS200EXAMG1A","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_fe069212-ad0d-4669-afdf-f6817fdaa298.jpg?v=1784890575","url":"https:\/\/www.electronicplc.com\/ar\/products\/is200examg1a-ge-exciter-attenuator-module-ex2100-series","provider":"Electronic PLC","version":"1.0","type":"link"}
