FAQ
FAQ
Q1: What is the Bently Nevada 128085-01 used for?
It is a Keyphasor® I/O Module that provides accurate shaft speed and phase reference signals for machinery protection and condition monitoring systems.
Q2: What is a Keyphasor signal?
A Keyphasor signal is a once-per-revolution or multiple-per-revolution pulse used as a timing reference for vibration analysis, phase measurements, and speed calculations.
Q3: How many channels does the module support?
The 128085-01 supports two independent Keyphasor input channels.
Q4: Which sensors can be connected to this module?
It accepts signals from proximity probes and magnetic pickup sensors used to detect shaft rotational events.
Q5: Does the module measure speed directly?
Yes. It processes pulse inputs to provide shaft speed and phase reference information for the 3500 monitoring system.
Q6: Is a separate power supply required?
No. The module receives power directly from the 3500 rack backplane.
Q7: Which systems is it compatible with?
It is designed specifically for the Bently Nevada 3500 Machinery Protection System and integrates with System 1® software.
Q8: What should be verified before replacement?
Verify the part number, I/O configuration, sensor type, rack compatibility, and system configuration settings before installation.
