The Bently Nevada 126648-01 is an enhanced keyer I/O module for the 3500/25 series.It is primarily used to provide keyer signals to monitoring modules within the 3500 system architecture.Product details are as follows:
Basic Information
Origin:USA
Dimensions:241.3mm×24.4mm×103.1mm(9.50in×0.96in×4.06in)
Weight:0.40kg(0.88lbs.)
Power Supply:-24VDC,maximum current per channel 40mA
Power Consumption:Typical power consumption is 3.2W
Features
Input Signal Compatibility:Accepts input signals from proximity probes or magnetic pickups.
Output Characteristics:Generates two buffered keyer outputs with a maximum buffered output impedance of 504Ω.Channel Configuration:A low-profile,two-channel interface provides keyphasor signals to monitoring modules within the 3500 chassis.
Application Scenario:Keyphasor signals are pulses with one or more events per revolution from a rotating shaft or gear.They provide precise timing measurements,enabling the 3500 monitoring module and external diagnostic equipment to measure shaft speed and vector parameters such as 1X vibration amplitude and phase.This module is suitable for rotating machinery requiring keyphasor signal monitoring,such as turbines,compressors,and generators,to monitor the equipment’s operating status and ensure safe and stable operation.
