This module provides critical real-time monitoring of electrical leakage relative to the system frame potential. By identifying and isolating ground faults, the board ensures the integrity of the turbine control matrix during startup, steady-state operation, and emergency shutdown sequences. It is widely utilized in heavy industrial environments, including steam and gas turbine power generation, petrochemical facilities, and large-scale processing plants.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIntegrated fault path telemetry for high-voltage excitation array protection.\u003c\/li\u003e\n\u003cli\u003eFeatures a robust Motorola NPN power transistor with an aluminum heat sink for thermal management.\u003c\/li\u003e\n\u003cli\u003eIncludes six dedicated test points (TP0-TP5) for precise system diagnostics and calibration.\u003c\/li\u003e\n\u003cli\u003eEquipped with high-stability cement wire-wound resistors and 600V-rated Seacor polyester film capacitors.\u003c\/li\u003e\n\u003cli\u003eDesigned for secure mounting via snap-in PCB screw mounts and nylon guide pins.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eDS3800NGDC1A1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMark IV Speedtronic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Fanuc\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\u003eTransistor Type\u003c\/td\u003e\n\u003ctd\u003eMotorola NPN with heat sink\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacitor Ratings\u003c\/td\u003e\n\u003ctd\u003e600 VDC (film), 25 VDC (electrolytic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTest Points\u003c\/td\u003e\n\u003ctd\u003e6 (TP0-TP5)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003e1x 3-pin male header, 1x 2-position terminal block, 1x 5-position terminal strip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the control system is fully powered down before inserting or removing the module from the rack.\u003c\/li\u003e\n\u003cli\u003eHandle the PCB by the edges to prevent electrostatic discharge (ESD) damage to the integrated circuits.\u003c\/li\u003e\n\u003cli\u003eVerify that the nylon guide pins are properly aligned with the chassis mounting points before securing the board.\u003c\/li\u003e\n\u003cli\u003eEnsure all field wiring to the terminal strips and headers is properly strain-relieved to prevent vibration-induced disconnects.\u003c\/li\u003e\n\u003cli\u003eConfirm that TP0 is correctly referenced to the system frame ground during commissioning.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the DS3800NGDC1A1A?\u003c\/h3\u003e\u003cp\u003eThis module acts as a ground detector within the Mark IV Speedtronic system, monitoring for electrical leakage to the frame to prevent damage to the turbine control and excitation components.\u003c\/p\u003e\u003ch3\u003eAre the test points on this board accessible during operation?\u003c\/h3\u003e\u003cp\u003eYes, the six test points (TP0-TP5) are provided for on-board diagnostics; however, caution should be exercised when probing live circuits to avoid shorting adjacent components.\u003c\/p\u003e\u003ch3\u003eWhat type of resistors are used on this board?\u003c\/h3\u003e\u003cp\u003eThe module utilizes cement wire-wound resistors, which are selected for their high-temperature stability and reliability in demanding industrial environments.\u003c\/p\u003e","brand":"GE FANUC","offers":[{"title":"Default Title","offer_id":51006418223356,"sku":"DS3800NGDC1A1A","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_776d6ec0-e385-4050-ad55-50f6463cb0e9.jpg?v=1787503373","url":"https:\/\/www.electronicplc.com\/es\/products\/mark-iv-speedtronic-ds3800ngdc1a1a-ge-ground-detector-module","provider":"Electronic PLC","version":"1.0","type":"link"}
