This configuration combines the main monitor board with a -01 Prox\/Velom I\/O module featuring internal terminations, alongside a -02 ATEX\/IECEx hazardous area approval option. It conditions incoming signals from seismic or proximity transducers to evaluate mechanical parameters against user-programmable alarm setpoints, safeguarding critical reciprocating machinery.\u003c\/p\u003e\n\u003ch3\u003eChannel Functions and Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe module operates across four independent channels configured in pairs, allowing users to execute up to two distinct measurement functions simultaneously per channel group. Supported programmable functions include impulse acceleration, reciprocating acceleration, reciprocating velocity, and low-frequency reciprocating velocity.\u003c\/p\u003e\n\u003cp\u003eIncoming waveforms pass through specialized filter blocks and multi-stage integration or detection algorithms to isolate mechanical impacts and piston rod events from background electrical noise.\u003c\/p\u003e\n\u003ch3\u003eAlarm Management and System Integration\u003c\/h3\u003e\n\u003cp\u003eReal-time measurement data is evaluated continuously against software-configured Alert and Danger thresholds to drive protection relays and warn plant operators of mechanical wear or failure risks. In addition to discrete alarm states, 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\u003eFront-panel coaxial connectors provide short-circuit-protected buffered transducer outputs for diagnostic analysis, while status LEDs indicate operational readiness and communication traffic.\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\/70-01-02\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 Machinery Protection System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eRecip Impulse\/Velocity Monitor Module\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 Measurements\u003c\/td\u003e\n\u003ctd\u003eImpulse Acceleration, Recip Acceleration, Recip Velocity, Low Frequency Recip Velocity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Module Type\u003c\/td\u003e\n\u003ctd\u003e-01 Prox\/Velom I\/O Module with Internal Terminations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAgency Approval Option\u003c\/td\u003e\n\u003ctd\u003e-02 ATEX, IECEx (Zone 2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransducer Power Supply\u003c\/td\u003e\n\u003ctd\u003e-22 Vdc minimum (40 mA maximum)\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 (600 $\\Omega$ maximum 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\u003eMonitor Module Dimensions\u003c\/td\u003e\n\u003ctd\u003e241.3 mm x 24.4 mm x 241.8 mm (9.50 in x 0.96 in x 9.52 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMonitor Module Weight\u003c\/td\u003e\n\u003ctd\u003e0.91 kg (2.0 lb)\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 primary machine types utilize the \u003cstrong\u003e3500\/70-01-02\u003c\/strong\u003e monitor module?\u003c\/p\u003e\n\u003cp\u003eA: This module is designed for reciprocating compressor applications to monitor mechanical integrity across compressor crankcases and crossheads.\u003c\/p\u003e\n\u003cp\u003eQ: Can the four channels run different measurement algorithms simultaneously?\u003c\/p\u003e\n\u003cp\u003eA: Yes, channels are programmed in pairs, enabling channel groups 1-2 and 3-4 to execute different or identical vibration monitoring functions concurrently.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":68027650605365,"sku":"3500\/70-01-02","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/350045-01-00_57949d9a-6363-4d72-9c9f-0586a1be25c9.png?v=1793694455","url":"https:\/\/www.5gplc.com\/products\/bently-nevada-3500-70-01-02-recip-impulse-velocity-monitor-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
