More Information

Overview Manuals Monitor Match Installation Fault Checks Application
  • Pairs with the 3500/40M Proximitor Monitor in the 3500 rack
  • Combines internal field terminations with intrinsic-safety barriers
  • Requires the documented 3500/04 intrinsic-safety earthing arrangement

Bently Nevada 135489-04 is a rear-slot 3500/40M Proximitor I/O module designed for proximity-transducer channels that require internal barriers and internal terminations.

The module carries field signals through the documented intrinsic-safety arrangement to the paired monitor used for radial vibration, thrust position and other supported proximity measurements.

Before installation or replacement, verify the exact spare number, rack position, monitor pairing, transducer family, IS earth, hazardous-area approval and saved channel configuration.

Availability, condition, price, and shipping time for 135489-04 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Pair the module only with the documented 3500/40M Proximitor Monitor
  • Match every channel to its configured proximity-transducer system
  • Keep the monitor and rear I/O module in the corresponding rack positions
  • Connect the internal barriers through the documented 3500/04 IS earth arrangement
  • Verify hazardous-area entity parameters and field wiring before energizing
  • Do not combine internal-barrier wiring with an unreviewed external-barrier scheme
  • Compare channel Not OK conditions with the paired monitor diagnostics
  • Inspect transducer power, gap voltage, field continuity and the IS earth path
  • Confirm channel type and scale after any monitor or I/O module replacement
  • Radial vibration measurement with compatible proximity-transducer systems
  • Thrust position and differential-expansion measurement in machinery protection systems
  • Eccentricity and REBAM measurements supported by the paired 3500/40M monitor
Description
Bently Nevada 135489-04 is a 3500/40M Proximitor I/O module with internal barriers and internal terminations for the 3500 machinery protection system.

Installed in the rear full-height slot, it interfaces proximity-transducer channels with the paired 3500/40M monitor while providing the documented intrinsic-safety barrier arrangement.

Before installation or replacement, confirm the exact spare number, paired 3500/40M monitor, compatible transducer system, IS earthing arrangement, rack slot, hazardous-area documentation and saved channel configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can Bently Nevada 3500/40M 135489-04 be used with any proximity transducer system?
No. Confirm the configured Proximitor Sensor family, probe and extension-cable electrical length, sensitivity, channel configuration and intrinsic-safety entity parameters. A transducer that can be physically connected is not necessarily a calibrated or approved measuring chain.
Can Bently Nevada 135489-04 replace a 3500/40M I/O module that uses external barriers?
Not without engineering review. 135489-04 contains internal barriers and internal terminations, so field wiring, earthing and hazardous-area documentation differ from external-barrier arrangements.
Does Bently Nevada 135489-04 require an intrinsic-safety earth connection?
Yes. The internal-barrier system requires the documented 3500/04 IS Earthing Module and an installation that complies with the applicable hazardous-area drawing.
Where is Bently Nevada 135489-04 installed in the 3500 rack?
It occupies the rear full-height I/O position corresponding to its paired 3500/40M monitor; verify slot alignment before insertion.
Why can Bently Nevada 135489-04 show a Not OK channel after replacement?
Check transducer power and gap, field continuity, polarity, IS earth, monitor/I/O slot pairing, channel type and the restored scale and alarm configuration.
What should be saved before replacing Bently Nevada 135489-04?
Export the rack configuration and record monitor and I/O slot positions, transducer type, channel scale, alarms, field terminals, barrier earth and active diagnostic events.
How should Bently Nevada 135489-04 be validated after installation?
Verify the IS earth and terminal map, compare gap and dynamic signals with the saved baseline, prove channel diagnostics and alarm paths, and observe each measurement during a controlled machine state.
