PRODUCT DESCRIPTION
Four channel proximity module
Bently Nevada 125680-01 is a proximity I/O module. The I/O assembly connects proximity-transducer signals to a compatible 3500/40M front monitor. The internal, external and barrier variants provide different field-wiring arrangements. It is not a standalone measuring instrument and must be paired with the intended monitor and transducer chain.
The official parts table identifies 125680-01 as a 3500/40M Proximitor I/O assembly. Match the installed transducer type, channel-pair configuration and termination arrangement. Do not transfer a different monitor family or barrier option merely because the module fits the rack.

ACTUAL APPLICATIONS
Applications for 3500 machinery monitoring 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 · SHAFT VIBRATION
Radial vibration measurement
The manufacturer documents radial-vibration monitoring from compatible proximity signals. Configured channels provide vibration and gap values for machinery operation and maintenance. -
02 · AXIAL POSITION
Thrust and expansion measurements
The monitor can evaluate thrust position or differential expansion when the appropriate transducer sensitivity and channel configuration are selected. These functions must match the installed measurement geometry. -
03 · BEARING MONITORING
Configured REBAM channels
The documented REBAM function uses specialized signal conditioning and compatible transducers. It requires the M monitor and later software and firmware levels, not just an available rack slot.

FOUR CHANNEL PROXIMITY MODULE
Integrating 125680-01
The I/O assembly connects proximity-transducer signals to a compatible 3500/40M front monitor. The internal, external and barrier variants provide different field-wiring arrangements. It is not a standalone measuring instrument and must be paired with the intended monitor and transducer chain.
Use the documented front monitor and I/O pairing with a compatible proximity chain. External termination blocks and cables are separately selected and cannot be used with internal-termination I/O. REBAM additionally requires the M monitor and the specified later software and firmware.
Fit the matched front and rear assemblies in their corresponding full-height rack positions. Follow monitor user guide 143488 for signal, transducer-power and grounding connections. Configure channel pairs for the intended function and use the applicable intrinsic-safety drawings where barriers are present.
Features:
- Match complete spare-part identity, module generation, rack position and mating input/output assembly
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 125680-01 proximity I/O module requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 125680-01 requires comparing complete spare-part identity, module generation, rack position and mating input/output assembly. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
Use the documented front monitor and I/O pairing with a compatible proximity chain. External termination blocks and cables are separately selected and cannot be used with internal-termination I/O. REBAM additionally requires the M monitor and the specified later software and firmware.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 125680-01 proximity I/O module requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 125680-01
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
How is the exact replacement identified?
The official parts table identifies 125680-01 as a 3500/40M Proximitor I/O assembly. Match the installed transducer type, channel-pair configuration and termination arrangement. Do not transfer a different monitor family or barrier option merely because the module fits the rack. -
What is the function of this component?
The I/O assembly connects proximity-transducer signals to a compatible 3500/40M front monitor. The internal, external and barrier variants provide different field-wiring arrangements. It is not a standalone measuring instrument and must be paired with the intended monitor and transducer chain. -
Which installed components must be compatible?
Use the documented front monitor and I/O pairing with a compatible proximity chain. External termination blocks and cables are separately selected and cannot be used with internal-termination I/O. REBAM additionally requires the M monitor and the specified later software and firmware. -
Where is this component used?
The manufacturer documents radial-vibration monitoring from compatible proximity signals. Configured channels provide vibration and gap values for machinery operation and maintenance. -
What must be checked during installation?
Fit the matched front and rear assemblies in their corresponding full-height rack positions. Follow monitor user guide 143488 for signal, transducer-power and grounding connections. Configure channel pairs for the intended function and use the applicable intrinsic-safety drawings where barriers are present. -
Can every channel use an unrelated measurement function?
No. Channels are programmed as pairs: channels 1 and 2 share one function, and channels 3 and 4 share another or the same function. Certain configurations permit only one enabled channel in a pair. -
What additional versions does REBAM require?
The datasheet specifies 3500/40M firmware 2.1, 3500/01 software 3.30, 3500/02 software 2.40, 3500/03 software 1.40 and DM2000 3.40, or later. These are application requirements, not confirmation of the supplied module revision.
