PRODUCT DESCRIPTION
Shaft phase reference module
Bently Nevada 3500/25-01-02-00 is a enhanced Keyphasor module. The assembly belongs to the Keyphasor signal chain that supplies timing references to rack monitors. Suitable input pulses indicate the shaft reference mark for speed and phase-related measurements. Match the front card, I/O termination and installed transducer configuration before replacement.
This order selects one half-height two-channel Keyphasor card, external-termination I/O and no agency approval option. The external block and cable must be selected separately. Match the full installation before applying the enhanced signal-processing functions or configuring a redundant reference arrangement.

ACTUAL APPLICATIONS
Applications for 3500 Keyphasor signal system
These applications describe manufacturer-documented family use. They do not establish that this exact ordering code was installed at a named customer site.
-
01 · PHASE REFERENCE
Timing for vibration phase measurements
The Keyphasor pulse provides timing information used by compatible monitors for vector measurements such as 1X vibration amplitude and phase. The complete sensing arrangement must resolve the intended shaft reference mark. -
02 · SHAFT SPEED
Speed measurements from reference pulses
Suitable probe or magnetic-pickup signals identify rotating-shaft events. Select the correct event count and threshold; low-speed limitations of the chosen transducer must be considered. -
03 · REDUNDANT REFERENCES
Primary and secondary timing channels
For documented TMR use, two Keyphasor modules operate in parallel to provide primary and secondary references. A single spare or half-height card alone does not establish the complete redundant arrangement.

SHAFT PHASE REFERENCE MODULE
Integrating 3500/25-01-02-00
The assembly belongs to the Keyphasor signal chain that supplies timing references to rack monitors. Suitable input pulses indicate the shaft reference mark for speed and phase-related measurements. Match the front card, I/O termination and installed transducer configuration before replacement.
The official successor for PWA 125792-01 is 149369-01, with stated form, fit and function downward compatibility. External termination blocks cannot be used with internal-termination I/O. Isolated I/O has additional phase shift and requires external power for a Proximitor application.
Use the correct half-height mounting adapter and matching rear I/O, following Keyphasor guide 129770. Verify the target, selected threshold and termination arrangement before configuration. Do not infer an exact supplied firmware version from the revision of the product datasheet.
Features:
- Match monitor generation, matched front and rear assemblies, wiring and software
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 3500/25-01-02-00 enhanced Keyphasor module requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 3500/25-01-02-00 requires comparing monitor generation, matched front and rear assemblies, wiring and software. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
The official successor for PWA 125792-01 is 149369-01, with stated form, fit and function downward compatibility. External termination blocks cannot be used with internal-termination I/O. Isolated I/O has additional phase shift and requires external power for a Proximitor application.
The manufacturer names 149369-01 as the direct plug-in successor to PWA 125792-01. No exact discontinuation date or supplied hardware revision is established. I/O selection and enhanced processing applications still require their documented checks.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 3500/25-01-02-00 enhanced Keyphasor module requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 3500/25-01-02-00
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
How is 3500/25-01-02-00 identified?
This order selects one half-height two-channel Keyphasor card, external-termination I/O and no agency approval option. The external block and cable must be selected separately. Match the full installation before applying the enhanced signal-processing functions or configuring a redundant reference arrangement. -
What is the function of this component?
The assembly belongs to the Keyphasor signal chain that supplies timing references to rack monitors. Suitable input pulses indicate the shaft reference mark for speed and phase-related measurements. Match the front card, I/O termination and installed transducer configuration before replacement. -
Which installed equipment must be matched?
The official successor for PWA 125792-01 is 149369-01, with stated form, fit and function downward compatibility. External termination blocks cannot be used with internal-termination I/O. Isolated I/O has additional phase shift and requires external power for a Proximitor application. -
Where is this component used?
The Keyphasor pulse provides timing information used by compatible monitors for vector measurements such as 1X vibration amplitude and phase. The complete sensing arrangement must resolve the intended shaft reference mark. -
What must be checked during installation?
Use the correct half-height mounting adapter and matching rear I/O, following Keyphasor guide 129770. Verify the target, selected threshold and termination arrangement before configuration. Do not infer an exact supplied firmware version from the revision of the product datasheet. -
Is there an official direct replacement for 125792-01?
Yes. Datasheet 141532 expressly identifies 149369-01 as a direct plug-in replacement for 125792-01 with complete downward form, fit and function compatibility. The statement does not supply an exact end-of-life date. -
Does isolated Keyphasor I/O behave identically for phase measurement?
No. The manufacturer says isolated I/O adds slightly more phase shift than non-isolated I/O. It was primarily intended for shaft-speed measurement; Proximitor use also needs an external power supply.
