Bently Nevada 3500/25 126398-01 Enhanced Keyphasor Module 30-Day Returns！

Frequently Asked Questions (FAQ)

What is the main function of the Bently Nevada 3500/25 Enhanced Keyphasor Module?
It converts signals from proximity probes or magnetic pickups into digital Keyphasor signals, which provide precise timing information to measure shaft speed and phase in rotating machinery.

How many Keyphasor signals can the module handle in a single rack configuration?
A standard system can handle up to four Keyphasor signals, or up to eight in a paired configuration with four modules.

What types of input signals does the module accept?
The module accepts signals from proximity transducers and magnetic pickups, with specific voltage ranges based on the I/O module type.

Can this module be used in TMR (Triple Modular Redundant) systems?
Yes. Two Keyphasor modules are required to provide primary and secondary signals for TMR applications.

What is the minimum speed required for magnetic pickup inputs?
Magnetic pickup inputs require a shaft speed greater than 200 rpm (3.3 Hz) to generate usable signals.

What are the physical dimensions and weight of the main module?
The main module measures 119.9 mm x 24.4 mm x 256.5 mm and weighs 0.34 kg.

What is the purpose of the Isolated I/O Module option?
The Isolated I/O Module provides electrical isolation for applications where Keyphasor signals are shared across multiple systems, especially suited for magnetic pickup inputs.

Is firmware upgrade possible in the field?
Yes, the Enhanced Keyphasor Module supports field-upgradeable firmware, allowing updates without removing the module.
