It provides physical connection interfaces for resistance temperature detectors (RTDs) and isolated tip thermocouples (TCs). The module features internal terminations, allowing field wiring from temperature sensors to connect directly to the terminal block on the rear of the 3500 rack without requiring external termination blocks.\u003c\/p\u003e\n\u003cp\u003eThis I\/O module interfaces directly with the 3500\/65 monitor module to condition continuously sampled temperature data. It is primarily utilized in critical machinery applications, including steam and gas turbine bearings, large motor stator windings, compressor discharge lines, and industrial pump housing monitoring. The module supports both continuous alarm verification and machinery trip logic integration when combined with the 3500 system relay modules.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul class=\"KsbFXc U6u95 list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan class=\"T286Pc\"\u003e\u003cspan class=\"Yjhzub\"\u003ePart Number:\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e172103-01\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan class=\"T286Pc\"\u003e\u003cspan class=\"Yjhzub\"\u003eManufacturer:\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eBently Nevada (Baker Hughes)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan class=\"T286Pc\"\u003e\u003cspan class=\"Yjhzub\"\u003eMonitor Compatibility:\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e3500\/65 16-Channel Temperature Monitor\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan class=\"T286Pc\"\u003e\u003cspan class=\"Yjhzub\"\u003eTermination Type:\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eInternal Terminations (Includes 20-pin terminal plug, part number 173005)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan class=\"T286Pc\"\u003e\u003cspan class=\"Yjhzub\"\u003eFunctional Group:\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eMachinery Protection System Spare Parts\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"NRefec\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"cZCYO firstRow\"\u003e\n\u003cth class=\"iry6k\" colspan=\"undefined\"\u003eParameter\u003c\/th\u003e\n\u003cth class=\"iry6k\" colspan=\"undefined\"\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"cZCYO\"\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e\u003cspan class=\"Yjhzub\"\u003eModel\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e172103-01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"cZCYO\"\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e\u003cspan class=\"Yjhzub\"\u003eBrand\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003eBently Nevada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"cZCYO\"\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e\u003cspan class=\"Yjhzub\"\u003eProduct Type\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003eTemperature Monitor I\/O Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"cZCYO\"\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e\u003cspan class=\"Yjhzub\"\u003eSeries\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e3500 Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"cZCYO\"\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e\u003cspan class=\"Yjhzub\"\u003eInput Channels\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e16 independent channels (RTD or Isolated Tip TC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"cZCYO\"\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e\u003cspan class=\"Yjhzub\"\u003eInput Impedance\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd class=\"cOeeGf\" colspan=\"undefined\"\u003e\u0026gt;
