This module serves as the primary interface for Keyphasor transducers, providing essential phase reference signals to the monitoring system. It receives input signals from proximity probes or magnetic pickups and converts them into digital Keyphasor signals, which are used by other modules in the rack for phase-related measurements such as 1X vibration, phase angle, and speed.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProvides phase reference signals for machinery protection and condition monitoring.\u003c\/li\u003e\n\u003cli\u003eSupports both proximity probe and magnetic pickup (MPU) inputs.\u003c\/li\u003e\n\u003cli\u003eEnhanced processing capabilities for high-speed signal acquisition.\u003c\/li\u003e\n\u003cli\u003eConfigurable input thresholds to accommodate various transducer types.\u003c\/li\u003e\n\u003cli\u003eIntegrates seamlessly into the 3500 rack architecture via the backplane.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Model\u003c\/td\u003e\n\u003ctd\u003e3500\/25 125792-01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e3.2 Watts typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e21.8 kOhm minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProximity Input Range\u003c\/td\u003e\n\u003ctd\u003e-2V to -18V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMPU Input Range\u003c\/td\u003e\n\u003ctd\u003e5 mV to 50 V peak\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeed Range\u003c\/td\u003e\n\u003ctd\u003e1 RPM to 99,999 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e+\/- 0.1% of reading\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-30 degC to +65 degC (-22 degF to +149 degF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003e500 V channel-to-ground\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e15 to 30 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the 3500 rack is powered down before inserting or removing the module to prevent electrical damage.\u003c\/li\u003e\n\u003cli\u003eThe module should be seated firmly in the designated rack slot and secured using the front panel levers.\u003c\/li\u003e\n\u003cli\u003eUse shielded cabling for all transducer inputs to minimize electromagnetic interference (EMI).\u003c\/li\u003e\n\u003cli\u003eEnsure proper grounding of the 3500 rack chassis to a common instrument ground.\u003c\/li\u003e\n\u003cli\u003eHandle the module using ESD-safe practices to protect internal circuitry.\u003c\/li\u003e\n\u003cli\u003eVerify that the Keyphasor transducer gap and signal levels are within the specified input ranges during commissioning.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the 3500\/25 module?\u003c\/h3\u003e\u003cp\u003eThe 3500\/25 Enhanced Keyphasor Module conditions signals from speed\/phase transducers to provide a phase reference signal that is used by other monitors in the 3500 system for vibration and phase analysis.\u003c\/p\u003e\u003ch3\u003eCan this module accept both proximity probes and magnetic pickups?\u003c\/h3\u003e\u003cp\u003eYes, the module is designed to accept inputs from both proximity probes and magnetic pickups, with configurable settings to match the specific transducer type.\u003c\/p\u003e\u003ch3\u003eWhat is the operating temperature range for this unit?\u003c\/h3\u003e\u003cp\u003eThe module is rated for operation in environments ranging from -30 degC to +65 degC (-22 degF to +149 degF).\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":50726403539196,"sku":"125792-01","price":80.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_d8d9961f-0971-434c-be4e-bb5810aa992e.jpg?v=1785153521","url":"https:\/\/www.electronicplc.com\/ar\/products\/bently-nevada-162291-01-3500-33-16-channel-relay-module","provider":"Electronic PLC","version":"1.0","type":"link"}
