Its stated function is to condition low-level thermocouple signals through amplification, filtering, and cold-junction compensation (CJC) before temperature data is processed by the controller. The supplied specifications also list a plug-in card format, dimensions of 22 x 23 x 5 cm, and a weight of 1.9 kg.\u003c\/p\u003e\n\u003ch3\u003eFunction and Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe NTCF board is described by component references as a thermocouple condition card for the Speedtronic Mark IV system, rather than Mark V. Thermocouple signals are used to monitor turbine temperatures; the resulting temperature information supports control and protection functions. The exact signal-processing stages and cold-junction compensation specifications for this revision require confirmation against model-specific technical documentation.\u003c\/p\u003e\n\u003ch3\u003eBoard Hardware and Connections\u003c\/h3\u003e\n\u003cp\u003ePublished component information identifies two board connectors, four potentiometers, five jumper switches, one resistor network, and multiple test points. These features are relevant when identifying the board during inspection or maintenance. Their adjustment procedures and electrical functions should be confirmed from the applicable circuit diagrams before changing any settings.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eDS3800NTCF1C1C\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 Type\u003c\/td\u003e\n\u003ctd\u003eThermocouple Conditioning Board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctional Acronym\u003c\/td\u003e\n\u003ctd\u003eNTCF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl System Series\u003c\/td\u003e\n\u003ctd\u003eSpeedtronic Mark IV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoard Connectors\u003c\/td\u003e\n\u003ctd\u003e218A4637-P4; 218A4553-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePotentiometers\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJumper Switches\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistor Networks\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e22 x 23 x 5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.9 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Which turbine control system is the DS3800NTCF1C1C associated with?\u003c\/p\u003e\n\u003cp\u003eA: Available component references identify it as a thermocouple condition card for the GE Speedtronic Mark IV system.
