Identified by the functional acronym TCQA, this board performs essential analog signal scaling, conditioning, acquisition, and distribution for turbine control and protection. It serves as a critical interface between field instrumentation—such as LVDTs, thermocouples, vibration sensors, pressure transmitters, and 4–20 mA devices—and the R, S, and T control cores of the Mark V system.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDesigned for Mark V turbine control systems (RST architecture).\u003c\/li\u003e\n\u003cli\u003e8 configurable analog input channels with selectable impedance (250, 500, 1200, and 2500 Ohm).\u003c\/li\u003e\n\u003cli\u003e4 dedicated analog output channels for actuator control.\u003c\/li\u003e\n\u003cli\u003e16-bit resolution with ±0.10% full-scale accuracy at 25 degC.\u003c\/li\u003e\n\u003cli\u003eEquipped with six 34-pin and two 40-pin connectors for system interfacing.\u003c\/li\u003e\n\u003cli\u003eConfigurable hardware jumpers (J1, J2, J5, J6, J7, J8) for current range and test port selection.\u003c\/li\u003e\n\u003cli\u003eConformal coating for protection against humidity and chemical corrosion.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTurbine speed and fuel regulation via servo-actuators.\u003c\/li\u003e\n\u003cli\u003eThermal diagnostics and exhaust temperature monitoring.\u003c\/li\u003e\n\u003cli\u003eGenerator and grid synchronization.\u003c\/li\u003e\n\u003cli\u003eAerodynamic operational safety and pressure monitoring.\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\u003eDS215TCQAG1BZZ01A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctional Acronym\u003c\/td\u003e\n\u003ctd\u003eTCQA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProcessor\u003c\/td\u003e\n\u003ctd\u003eIntel 80196\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e16-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±0.10% full scale at 25 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLinearity\u003c\/td\u003e\n\u003ctd\u003e±0.05%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnectors\u003c\/td\u003e\n\u003ctd\u003e6x 34-pin, 2x 40-pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.6 kg\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 powered down before inserting or removing the board.\u003c\/li\u003e\n\u003cli\u003eHandle the module using ESD-safe practices to prevent damage to sensitive components.\u003c\/li\u003e\n\u003cli\u003eThe board is factory-drilled for mounting; ensure it is properly seated in the Mark V cabinet.\u003c\/li\u003e\n\u003cli\u003eUse two hands when manipulating screws and washers to prevent dropping metal debris onto live circuitry.\u003c\/li\u003e\n\u003cli\u003eVerify correct alignment using the marked board edges before securing.\u003c\/li\u003e\n\u003cli\u003eEnsure all ribbon cables are firmly seated in their respective connectors (JA, JB, JD, JE, JG, 3PL).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the DS215TCQAG1BZZ01A?\u003c\/h3\u003e\u003cp\u003eIt is a dedicated analog I\/O circuit board with firmware, designed for use within the legacy General Electric (GE) Mark V gas and steam turbine control systems.\u003c\/p\u003e\u003ch3\u003eWhat types of inputs does DS215TCQAG1BZZ01A read?\u003c\/h3\u003e\u003cp\u003eThe board is specifically designed to read LVDT (Linear Variable Differential Transformer) inputs along with standard 4-20 mA instrumentation.\u003c\/p\u003e\u003ch3\u003eHow are LVDT inputs processed?\u003c\/h3\u003e\u003cp\u003eLVDT inputs are read directly by the TCQA section of the module and communicated to the control processor via dedicated ribbon cabling.\u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":50766043447548,"sku":"DS215TCQAG1BZZ01A","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_53ec5533-d2e6-49dc-862f-adc8257c27e0.jpg?v=1785486210","url":"https:\/\/www.electronicplc.com\/ar\/products\/ge-mark-v-lm-ds215tcqag1bzz01a-analog-i-o-board","provider":"Electronic PLC","version":"1.0","type":"link"}
