FAQ
Frequently Asked Questions (FAQ)
Q1: What is the main function of the Bently Nevada 3500/25 Enhanced Keyphasor Module?
A1: 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.
Q2: How many Keyphasor signals can the module handle in a single rack configuration?
A2: A standard system can handle up to four Keyphasor signals, or up to eight in a paired configuration with four modules.
Q3: What types of input signals does the module accept?
A3: The module accepts signals from proximity transducers and magnetic pickups, with specific voltage ranges based on the I/O module type.
Q4: Can this module be used in TMR (Triple Modular Redundant) systems?
A4: Yes. Two Keyphasor modules are required to provide primary and secondary signals for TMR applications.
Q5: What is the minimum speed required for magnetic pickup inputs?
A5: Magnetic pickup inputs require a shaft speed greater than 200 rpm (3.3 Hz) to generate usable signals.
Q6: What are the physical dimensions and weight of the main module?
A6: The main module measures 119.9 mm x 24.4 mm x 256.5 mm and weighs 0.34 kg.
Q7: What is the purpose of the Isolated I/O Module option?
A7: The Isolated I/O Module provides electrical isolation for applications where Keyphasor signals are shared across multiple systems, especially suited for magnetic pickup inputs.
Q8: Is firmware upgrade possible in the field?
A8: Yes, the Enhanced Keyphasor Module supports field-upgradeable firmware, allowing updates without removing the module.
