- 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.

- 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
