The module employs a low-frequency AC injection method to monitor the electrical center of the field winding. Our engineers note that its ability to maintain consistent ground detection performance across both Simplex and TMR (Triple Modular Redundant) configurations makes it a superior choice for minimizing system downtime during fault isolation.\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Applications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003eLarge-scale synchronous generator shaft protection\u003c\/li\u003e\n    \u003cli\u003eEX2100e Excitation system ground fault monitoring\u003c\/li\u003e\n    \u003cli\u003eStandalone PGDM (Portable Ground Detector Module) systems\u003c\/li\u003e\n    \u003cli\u003eHigh-voltage field bus regulation in power plants\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eLogistics \u0026amp; Service Excellence\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExpress Global Shipping:\u003c\/strong\u003e Fast, secure transit via \u003cstrong\u003eFedEx, UPS, and DHL\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQuality Commitment:\u003c\/strong\u003e Every module is provided with a \u003cstrong\u003e12-month comprehensive warranty\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eReliability:\u003c\/strong\u003e Standard PCB coating ensures durability in industrial cabinet environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProfessional FAQ \u0026amp; Engineering Guide\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How do I select the correct PPT (Potential Transformer) secondary voltage via jumpers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The IS200EXAMG1BAA features JP1, JP2, and JP3. You must align these shunts with your specific system’s PPT secondary output to ensure the attenuation ratio is optimized. Refer to your system’s electrical drawing to match the jumper map exactly; failure to do so may result in distorted ground detection signals.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Why is there no LED indicator or testpoint on this board?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The module is designed for \"passive-active\" signal conditioning within the HVI (High Voltage Interface) cabinet. Diagnostic data is processed at the EGDM or DSPX controller level. Troubleshooting should be focused on verifying input voltage at E1\/E2 and signal continuity at the J2 connector.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can the IS200EXAMG1BAA be interchanged between different EX2100e revisions?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: This unit is backward compatible with the first two revisions of the EXAM series. However, always verify your board's revision BAA against your current ControlST software configuration to ensure compatibility with your existing excitation logic.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the significance of the metal oxide varistors (MOVs) on this board?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The MOVs act as transient surge suppressors. In an excitation system, sudden voltage spikes (field flashing) are common. These components protect the internal attenuation circuitry from destructive energy surges that could otherwise propagate into the field bus.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Selection Tip: When should I replace the entire EXAM board?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: If you notice intermittent \"Ground Fault\" alarms that cannot be cleared after checking the field bus cabling, or if you suspect contact degradation on the J2 9-pin connector, we recommend full board replacement to maintain the integrity of your excitation control loop.\u003c\/p\u003e","brand":"GE","offers":[{"title":"Default Title","offer_id":45219197878454,"sku":"IS200EXAMG1BAA","price":358.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/IS200EXAMG1BAA.jpg?v=1782378579","url":"https:\/\/www.plcsparehub.com\/products\/is200examg1baa-ge-ex2100e-exciter-attenuation-module-high-precision","provider":"Global PLC Spare Hub","version":"1.0","type":"link"}
