This 16-channel module is engineered to provide continuous thermal surveillance of critical rotating machinery components, such as radial and thrust bearings, stator windings, and motor housings. It accepts inputs from both Resistance Temperature Detectors (RTDs) and Thermocouples (TCs), converting these signals into digital temperature data that the system uses to trigger protective alarms and machinery trips.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"w-fit min-w-(--thread-content-width)\"\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChannel Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e16 independent temperature sensing channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMeasurement Types\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSupports Pt100\/Ni100\/Ni120 RTDs and Type J\/K\/E\/T\/S Thermocouples\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSignal Processing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh-speed 24-bit A\/D conversion for precise thermal tracking\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAccuracy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e±1.5°C at room temperature (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlarm Logic\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIndependent Alert and Danger setpoints for all 16 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSystem Interface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCommunicates via the 3500 rack backplane with the 3500\/22M Rack Interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePhysical Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.6 cm x 25.3 cm x 24.0 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.75 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-30°C to +65°C (-22°F to +150°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOperational Expertise\u003c\/h3\u003e\n\u003cp\u003eThe 145988-02 module is a cornerstone of proactive machinery maintenance. By monitoring the rate of temperature change and absolute thermal limits, it identifies lubrication failures, cooling system blockages, or electrical imbalances before they result in catastrophic equipment damage. The module features integrated self-diagnostics to detect sensor failures (NOT OK status), ensuring that false trips are minimized while maintaining maximum protection levels.\u003c\/p\u003e\n\u003ch3\u003eEngineering FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ\u003c\/strong\u003e: How does the 145988-02 module handle thermocouple cold-junction compensation?\u003cbr\u003e\u003cstrong\u003eA\u003c\/strong\u003e: Cold-junction compensation is managed at the I\/O module level (located at the rear of the rack).
