This specific configuration includes the core monitor module matched with an I\/O module featuring internal safety barriers and internal terminations (Part Number \u003cstrong\u003e135489-01\u003c\/strong\u003e), supporting four channels of proximity or acceleration inputs. It conditions raw sensor signals into vital vibration and position metrics, continuously comparing values against user-configured alarm setpoints to safeguard rotating machinery.\u003c\/p\u003e\n\u003ch3\u003eChannel Processing and Signal Filtering\u003c\/h3\u003e\n\u003cp\u003eThe module processes up to four input channels configured in pairs, allowing operators to implement dedicated monitoring strategies such as radial vibration or acceleration measurements. Incoming signals pass through high-precision filter blocks—including configurable high-pass, low-pass, and vector filters—to isolate mechanical vibration from electrical noise or runout.\u003c\/p\u003e\n\u003cp\u003eEach channel provides short-circuit-protected buffered transducer outputs directly on the front panel via coaxial connectors for diagnostic analysis.\u003c\/p\u003e\n\u003ch3\u003eAlarm Management and Intrinsic Safety Integration\u003c\/h3\u003e\n\u003cp\u003eReal-time data is continuously evaluated against programmable Alert and Danger thresholds to activate system relays and protect critical assets. In addition to discrete protection relays, the monitor supplies proportional +4 to +20 mA current values for each channel to interface with external control systems.\u003c\/p\u003e\n\u003cp\u003eThe integrated I\/O module incorporates internal safety barriers and internal terminations, making it suitable for hazardous area installations where signal isolation and space efficiency inside instrument cabinets are required.\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\u003cstrong\u003e3500\/42-02-R0\u003c\/strong\u003e\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\u003e4 x Proximity \/ Acceleration transducers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Module Type\u003c\/td\u003e\n\u003ctd\u003ePart No. \u003cstrong\u003e135489-01\u003c\/strong\u003e (Internal Barriers, Internal Terminations)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAgency Approval Option\u003c\/td\u003e\n\u003ctd\u003e-00 (None specified \/ standard commercial)\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\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.91 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA\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 type of I\/O module is bundled with the \u003cstrong\u003e3500\/42-02-R0\u003c\/strong\u003e configuration?\u003c\/p\u003e\n\u003cp\u003eA: It utilizes an I\/O module featuring built-in internal safety barriers and internal terminations (Part Number \u003cstrong\u003e135489-01\u003c\/strong\u003e) designed for four proximity or acceleration channels.\u003c\/p\u003e\n\u003cp\u003eQ: Can the monitor outputs handle external short circuits on the recorder loops?\u003c\/p\u003e\n\u003cp\u003eA: Yes, monitor operation remains unaffected by short circuits on the individual +4 to +20 mA recorder outputs due to embedded circuit protection.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":68025019892021,"sku":"3500\/42-02-R0","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/350045-01-00_ddccf043-bbef-4a09-98c7-2c6a44a09971.png?v=1793689879","url":"https:\/\/www.5gplc.com\/products\/3500-42-02-r0-bently-nevada-proximitor-seismic-monitor","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
