Operating as a Thermocouple Field Termination Assembly (TC FTA), this unit provides high-density signal termination and multiplexing capabilities for temperature measurement applications. It interfaces directly with Honeywell controller architectures, translating microvolt-level signals from field sensors into system-compatible formats.\u003c\/p\u003e\n\n\u003cp\u003eEngineered for dependability in harsh environments, the \u003cstrong\u003eMU-TAMT03\u003c\/strong\u003e accommodates up to 16 low-level analog inputs, specifically optimized for thermocouples and resistance temperature detectors (RTDs). This board features a local Cold Junction Reference (CJR) circuit embedded directly on the termination assembly. This localized CJR ensures highly accurate, localized temperature compensation, preventing thermal gradient errors and maintaining signal integrity from the termination point to the controller interface.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSupports up to 16 low-level analog input channels.\u003c\/li\u003e\n  \u003cli\u003eIntegrated Local Cold Junction Reference (CJR) for precise thermocouple temperature compensation.\u003c\/li\u003e\n  \u003cli\u003eRobust Field Termination Assembly (FTA) design for secure and organized wiring.\u003c\/li\u003e\n  \u003cli\u003eHigh noise immunity and signal protection for microvolt-level field signals.\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard industrial thermocouple and RTD sensor profiles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOil and gas refining and petrochemical processing units.\u003c\/li\u003e\n  \u003cli\u003ePower generation plant thermal monitoring and control.\u003c\/li\u003e\n  \u003cli\u003eChemical processing and reactor temperature monitoring.\u003c\/li\u003e\n  \u003cli\u003eGlass, steel, and high-temperature manufacturing operations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eHoneywell\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003ePart Number \/ Model\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e51309223-125\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eAlternate Model Number\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eMU-TAMT03\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eProduct Type\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eLow Level Analog Input Multiplexer TC FTA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eNumber of Channels\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e16 Inputs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eCold Junction Reference (CJR)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eLocal CJR\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eCompatible Sensor Types\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eThermocouples, RTDs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eShipping Weight\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e3.0 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cp\u003eProper installation of the \u003cstrong\u003e51309223-125\u003c\/strong\u003e multiplexer ensures safe operation and maximum measurement accuracy.
