Model \u003cstrong\u003e140734-02\u003c\/strong\u003e represents the core monitor module combined with the \u003cstrong\u003e140471-01\u003c\/strong\u003e I\/O module featuring internal terminations. It conditions raw transducer signals into critical vibration and position measurements, continuously evaluating parameters against user-programmable alarm setpoints to safeguard rotating equipment.\u003c\/p\u003e\n\u003ch3\u003eCore Architecture and Channel Processing\u003c\/h3\u003e\n\u003cp\u003eThe module operates within a standard Bently Nevada 3500 rack, processing up to four channels of transducer input simultaneously. Channels are configured in pairs, allowing users to execute distinct monitoring strategies—such as radial vibration, thrust position, or velocity tracking—across separate channel groups.\u003c\/p\u003e\n\u003cp\u003eInput signals undergo precise filtering, including configurable high-pass, low-pass, and vector filtering options, to isolate true mechanical vibration from background noise or electrical runout. Each channel provides dedicated buffered transducer outputs on the front panel via short-circuit-protected coaxial connectors.\u003c\/p\u003e\n\u003ch3\u003eAlarm Management and Signal Integration\u003c\/h3\u003e\n\u003cp\u003eThe monitor evaluates real-time data against software-configured Alert and Danger thresholds to drive relay modules and protect critical assets. In addition to discrete alarm outputs, the unit supplies proportional +4 to +20 mA current values for each channel to interface directly with external control or data recording systems.\u003c\/p\u003e\n\u003cp\u003eThe accompanying \u003cstrong\u003e140471-01\u003c\/strong\u003e I\/O module handles field wiring termination internally, streamlining installation within industrial instrument cabinets and supporting robust signal integrity under harsh operating conditions.\u003c\/p\u003e\n\u003ch3\u003eTechnical Parameters\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\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\u003e\n\u003cstrong\u003e140734-02\u003c\/strong\u003e (Monitor Module) + \u003cstrong\u003e140471-01\u003c\/strong\u003e (I\/O Module)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBently Nevada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e3500\/42M Proximitor Seismic Monitor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e4 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Inputs\u003c\/td\u003e\n\u003ctd\u003eProximity, velocity, or acceleration transducers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard Input Impedance\u003c\/td\u003e\n\u003ctd\u003e10 kΩ (Proximitor and acceleration inputs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransducer Power Supply\u003c\/td\u003e\n\u003ctd\u003e-24 Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecorder Output\u003c\/td\u003e\n\u003ctd\u003e+4 to +20 mA proportional to full scale\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Output Load Resistance\u003c\/td\u003e\n\u003ctd\u003e0 to 600 Ω (0 to +12 Vdc range across load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTypical Power Consumption\u003c\/td\u003e\n\u003ctd\u003e7.7 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Termination Type\u003c\/td\u003e\n\u003ctd\u003eInternal terminations\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: What transducer types are supported by the \u003cstrong\u003e140734-02\u003c\/strong\u003e monitor configuration?\u003c\/p\u003e\n\u003cp\u003eA: The monitor accepts inputs from proximity, velocity, or acceleration transducers depending on software configuration and the paired I\/O module type.\u003c\/p\u003e\n\u003cp\u003eQ: How do the recorder outputs handle short circuits in external loops?\u003c\/p\u003e\n\u003cp\u003eA: Monitor operation remains completely unaffected by short circuits on the individual +4 to +20 mA recorder outputs due to built-in circuit protection.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":68024153407797,"sku":"3500\/42M(140734-02+140471-01)","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/350045-01-001_896be2ef-837f-416a-83b0-d6ef32a2e83f.png?v=1793685380","url":"https:\/\/www.5gplc.com\/products\/bently-nevada-140734-02-140471-01-3500-42m-proximitor-seismic-monitor","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
