This module serves as a critical processing component in industrial power generation and petrochemical applications, managing turbine velocity loops and power regulation parameters. By processing real-time feedback from field instrumentation—including shaft speed, system pressure, and temperature sensors—the module executes precise closed-loop control algorithms. It also incorporates essential safety logic to trigger protective trip sequences in response to operational anomalies, such as over-speed conditions or loss of oil pressure, thereby safeguarding turbine integrity.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDesigned specifically for the GE Mark IV Speedtronic turbine control environment.\u003c\/li\u003e\n\u003cli\u003eIntegrated 12-channel relay output sub-assembly for discrete command execution.\u003c\/li\u003e\n\u003cli\u003eAdvanced signal conditioning to mitigate electrical noise from analog field sensor inputs.\u003c\/li\u003e\n\u003cli\u003eSupports seamless integration with host PLCs and HMI systems for centralized monitoring and data logging.\u003c\/li\u003e\n\u003cli\u003eRobust hardware design suitable for demanding industrial environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is primarily utilized in heavy industrial settings, including municipal power generation facilities, gas turbine control systems, and large-scale petrochemical refinery operations where precise turbine speed and load management are required.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eDS3820LT4A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric (GE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eMark IV Speedtronic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelay Channels\u003c\/td\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogic Power\u003c\/td\u003e\n\u003ctd\u003e+5 VDC, 8 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelay Power\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to +65 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the turbine control system is fully de-energized before attempting to insert or remove the module from the rack.\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 the rack slot is clean and free of debris to ensure proper seating of the connector pins.\u003c\/li\u003e\n\u003cli\u003eEnsure all field wiring for sensors and relay outputs is properly routed and shielded to minimize EMI\/RFI interference.\u003c\/li\u003e\n\u003cli\u003eConfirm that the power supply voltage levels match the module requirements (+5 VDC logic \/ 24 VDC relay) before applying power.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the DS3820LT4A?\u003c\/h3\u003e\u003cp\u003eThe DS3820LT4A acts as a controller module for the Mark IV Speedtronic system, managing turbine speed, load control, and safety trip logic based on real-time sensor feedback.\u003c\/p\u003e\u003ch3\u003eDoes this module support external communication?\u003c\/h3\u003e\u003cp\u003eYes, the module is designed to interface with higher-level automation systems, including HMIs and PLCs, to facilitate system-wide coordination and telemetry logging.\u003c\/p\u003e\u003ch3\u003eWhat are the power requirements for this unit?\u003c\/h3\u003e\u003cp\u003eThe module requires +5 VDC (8 A) for internal logic and 24 VDC for the relay output sub-assembly.\u003c\/p\u003e","brand":"GE FANUC","offers":[{"title":"Default Title","offer_id":51012022960380,"sku":"DS3820LT4A","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_16ff1837-4cea-47b5-b44c-25abdb3ee0c6.jpg?v=1787674005","url":"https:\/\/www.electronicplc.com\/es\/products\/ge-mark-iv-ds3820lt4a-lodtrak-controller-module","provider":"Electronic PLC","version":"1.0","type":"link"}
