PRODUCT DESCRIPTION
3500/25 149369-01 Enhanced Keyphasor monitor module
Bently Nevada 3500/25 149369-01 is a Enhanced Keyphasor monitor module for the Bently Nevada 3500/25 Keyphasor system. Convert proximity-probe or magnetic-pickup events into digital Keyphasor timing signals used for accurate shaft-speed and phase reference. Supply Keyphasor information to 3500 monitors and diagnostic equipment so rotating-speed, 1X vibration amplitude and phase can be evaluated together. Confirm the exact article, installed interfaces and controlled commissioning record before ordering.

ACTUAL APPLICATIONS
Application context for 3500/25 149369-01
Manufacturer documentation places the Enhanced Keyphasor Monitor Module in practical vibration applications. The three cases below describe different operating tasks in which 3500/25 149369-01 performs its documented product-family role with the configured companion equipment.
- 01 · WATER & WASTEWATER
Protect motor-pump alignment during post-overhaul run
In the automation chain for the couplings, motor bearings and pump housings, 3500/25 149369-01 handles its designated signal or control duty as a Enhanced Keyphasor Monitor Module. During post-overhaul run, the system uses this function to evaluate coupled-machine vibration at operating speed, helping it confirm the train returns to its reference condition. - 02 · MINING & METALS
Observe crusher bearing monitoring with Enhanced Keyphasor
As part of the crusher shafts and bearing pedestals, 3500/25 149369-01 performs its assigned control role as a Enhanced Keyphasor Monitor Module. During ore-grade transition, the system uses this function to track bearing response as crushing load changes, helping it support planned attention to a degrading bearing. - 03 · POWER GENERATION
Manage turbine shaft monitoring during run-up
Inside the journal bearings and probe tracks, 3500/25 149369-01 supports the configured automation role as a Enhanced Keyphasor Monitor Module. During run-up, the system uses this function to acquire the configured vibration, position or speed signal, helping it show shaft behavior as the machine crosses critical speed.

SYSTEM INTEGRATION
Match 3500/25 149369-01 to the installed Bently Nevada 3500/25 Keyphasor system
Bently Nevada 3500/25 149369-01 is a Enhanced Keyphasor monitor module documented for the Bently Nevada 3500/25 Keyphasor system. Convert proximity-probe or magnetic-pickup events into digital Keyphasor timing signals used for accurate shaft-speed and phase reference.
Supply Keyphasor information to 3500 monitors and diagnostic equipment so rotating-speed, 1X vibration amplitude and phase can be evaluated together. Confirm +0.8 v to -21.0 v, 21.8 kω at the terminals, mechanical location and the approved system configuration before connection.
Install two modules in the documented paired arrangement when a TMR application requires primary and secondary Keyphasor signals for the rack. Use qualified personnel, retain the official manufacturer instructions at the work location and save the final commissioning results with the equipment record.
Features:
- Exact identity: 3500/25 149369-01
- Product class: Enhanced Keyphasor monitor module
- Family: Bently Nevada 3500/25 Keyphasor system
The Bently Nevada 3500/25 149369-01 requires documented system integration before energising the equipment.
REPLACEMENT CONTROL
Verify the complete 3500/25 149369-01 configuration before exchange
Replace 3500/25 149369-01 only after matching the full product identity, +0.8 v to -21.0 v, 21.8 kω at the terminals and installed system role. A similar family name or partial article number does not establish direct interchangeability.
Photograph the module label, rack or control-unit position, every connector, cable route, shield, earth point and companion module before removal. Compare the documented electrical and communication limits against the saved project or rack configuration.
After installation, restore the controlled configuration and complete the model-specific checks described in the official manufacturer document. Record status indications, diagnostics, signal or communication results and the final acceptance evidence before release.
Features:
- Match exact 3500/25 149369-01 identity
- Confirm 21.8 kΩ at the terminals
- Record 0.2 V to 2.5 V
The Bently Nevada 3500/25 149369-01 requires documented replacement verification before energising the equipment.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 3500/25 149369-01
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What system information is needed to source 3500/25 149369-01?
Provide the complete module number, input transducer type, isolated or non-isolated I/O requirement, paired-channel plan, rack position and quantity. -
Can 149369-01 replace the earlier 125792-01 Keyphasor module?
Bently Nevada identifies 149369-01 as the updated direct plug-in replacement, but the installed I/O module, rack configuration and channel settings must still be verified. -
Which sensors can feed the Enhanced Keyphasor inputs?
Each channel can accept a compatible proximity probe or magnetic pickup within the documented voltage and frequency ranges. -
When should two Keyphasor modules be used in a TMR system?
Use two modules in parallel when the 3500 system requires both primary and secondary Keyphasor signals for Triple Modular Redundant operation. -
What should receiving inspection cover for a 149369-01 module?
Verify the exact label, half-height module format, coaxial connectors, card-edge condition, LEDs, supplied items and absence of transport damage. -
How should engineering choose automatic or manual threshold operation?
Use the official signal-amplitude and frequency limits for each mode, then validate stable triggering with the installed probe or magnetic pickup. -
What rack-space condition applies to the 3500/25 main module?
It occupies one half-height front slot and needs the specified mounting adapter when installed in a full-height rack position. -
Which measurements confirm successful Keyphasor commissioning?
Verify clean timing pulses, correct event count per revolution, shaft-speed accuracy, buffered outputs, phase reference and TX/RX communication with the RIM.
