Bently Nevada 3500/50 133388-02 is a two-channel 3500 tachometer module. It measures rotational speed from compatible proximity-probe or magnetic-pickup inputs.
- Measures shaft rotational speed from pulse or keyphasor signals
- Provides speed values and alarm comparison in the 3500 rack
- Supports independent channel configuration
- Communicates module status and measured values to the rack interface
3500/50 133388-02 installs with 3500 rack, compatible I/O module, proximity probe or magnetic pickup, speed reference target in an engineered 3500 machinery protection system configuration.
The commissioning workflow covers installed-hardware matching, controlled start-up and functional verification for this 3500/50 tachometer module.
Important Notice: Confirm the complete 3500/50 133388-02 marking, installed-system configuration, field connections and controlled functional test before commissioning or replacement.

3Record sensor type, polarity, pulses per revolution, and scale.
4Preserve shield and input wiring identity.
5Use ESD controls and inspect backplane connectors.
6Confirm channel setpoints and rack communication after insertion.
7Compare indicated speed with a controlled reference at several points.
8Prove alarms, relays, and machine permissives before service.
Technical notes
Record channel input type, pulses per revolution, scale, setpoints, and voting before replacement, then verify indicated speed against a controlled reference throughout the required operating range.
FAQ View All FAQ
-
What isolation is required before installing 3500/50 133388-02?Place turbine shaft-speed monitoring in the approved maintenance state, isolate every applicable power, signal, and stored-energy source, and prove the work area safe.
-
Which configuration check is essential when commissioning 3500/50 133388-02?Restore only the approved model-specific channel, range, address, scale, or interface settings and compare them with the physical installation before enabling the process function.
-
How can an engineer function-test 3500/50 133388-02 after installation?Apply a controlled input, reference, or limited output appropriate to 3500/50 tachometer module, observe the system indication and diagnostics, and confirm the intended process response.
-
What should be checked if 3500/50 133388-02 reports an unstable or incorrect value?Check seating, supply, grounding, shielding, matched components, mechanical installation, and the signal path before changing configuration or replacing additional hardware.
-
Can 3500/50 133388-02 be replaced by a visually similar model without review?No. Verify the complete part number, electrical execution, connector arrangement, companion hardware, and approved software or rack configuration.
-
What commissioning evidence should be retained for 3500/50 133388-02?Retain the full 3500/50 133388-02 identity, as-left wiring and settings, measured functional-test results, final diagnostics, and authorization to return the affected equipment to service.
-
Which installed hardware must be matched before fitting 3500/50 133388-02?Match the complete 3500/50 133388-02 marking to 3500 rack and compatible I/O module, then confirm the assigned 3500 machinery protection system position and approved system configuration.
-
How should the field connections for 3500/50 133388-02 be recorded before replacement?Record terminal or connector identity, polarity, shield, cable tag, channel assignment, and the as-found diagnostic state before disconnecting 3500/50 133388-02.
