This module is critical for generator protection, acting as a bridge and monitoring interface that applies a low-frequency AC signal to the field windings for ground fault detection. By working in conjunction with the EGDM module, the IS200EXAMG1A facilitates the identification of insulation degradation or leakage currents, enabling proactive maintenance strategies that prevent potential generator damage and unplanned outages in power generation and heavy industrial environments.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDesigned for integration within the EX2100 Excitation Control architecture.\u003c\/li\u003e\n\u003cli\u003eSupports high-reliability redundant operation via M1 and M2 controller switching.\u003c\/li\u003e\n\u003cli\u003eFeatures precision sensing circuitry to monitor field ground leakage.\u003c\/li\u003e\n\u003cli\u003eConfigurable signal attenuation and bridge logic via onboard jumpers (JP1, JP2, JP3).\u003c\/li\u003e\n\u003cli\u003eRobust physical interface including dedicated ground detector cabling and high-current stab-on connectors (Vbus-p\/Vbus-n).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\" cellpadding=\"5\" cellspacing=\"0\"\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\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE General Electric\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\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eExciter Attenuator Module (EXAM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temp\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\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.52 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure all power is disconnected from the excitation system before installing or removing the module.\u003c\/li\u003e\n\u003cli\u003eThe module is typically installed within the auxiliary cabinet of the EX2100 system.\u003c\/li\u003e\n\u003cli\u003eEnsure all cabling, including the 9-position ground detector connector and high-current E1\/E2 stab-on connectors, is properly seated and secured to prevent intermittent faults.\u003c\/li\u003e\n\u003cli\u003eVerify jumper settings (JP1, JP2, JP3) match the site-specific configuration requirements before commissioning.\u003c\/li\u003e\n\u003cli\u003eHandle with standard ESD precautions to protect sensitive onboard components.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the primary function of the IS200EXAMG1A?\u003c\/strong\u003e\u003cbr\u003eIt acts as an attenuator and bridge module that injects a low-frequency AC test signal into the field winding to detect potential ground faults in the excitation system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this module support redundant control systems?\u003c\/strong\u003e\u003cbr\u003eYes, the IS200EXAMG1A is designed to support redundancy, allowing for seamless switching between M1 and M2 controllers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich module does the EXAM interface with for measurements?\u003c\/strong\u003e\u003cbr\u003eThe EXAM module transmits control and sense signals to the EGDM module, which performs the final analysis and measurement of field leakage currents.\u003c\/p\u003e","brand":"GE FANUC","offers":[{"title":"Default Title","offer_id":43981787168858,"sku":"IS200EXAMG1A","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/wm_1_e4c5fde7-ada2-444a-814c-e00fc16a738a.jpg?v=1788230606","url":"https:\/\/www.spareoil.com\/products\/is200examg1a-ge-exciter-attenuator-module-ex2100-series","provider":"SpareOil Automation","version":"1.0","type":"link"}
