Vibration Monitoring Solution – Bently Nevada 3500/42-01-00 | 3500 Series
Where This Product Is Used
The Bently Nevada 3500/42-01-00 Internal I/O Module (part numbers 176449-02 + 128229-01) is purpose-built for continuous machinery protection and condition monitoring in mission-critical industrial environments. Typical deployment sites include:
- Oil & Gas Upstream/Downstream: Compressor trains, gas turbines, and centrifugal pumps on offshore platforms and onshore processing facilities
- Power Generation: Steam turbines, hydro generators, and combined-cycle plant rotating equipment requiring 24/7 vibration surveillance
- Petrochemical & Refining: Reactor feed pumps, cracked-gas compressors, and critical agitators where unplanned downtime carries multi-million-dollar consequences
- LNG Terminals: Main refrigerant compressors and boil-off gas handling systems demanding API 670-compliant monitoring
- Pulp & Paper / Mining: Large induced-draft fans, ball mills, and kiln drives integrated into plant-wide DCS/SCADA architectures

Application-Specific FAQ
Q: Is the 3500/42-01-00 compatible with both proximitor and velocity inputs?
A: Yes. The module supports eddy-current (proximitor), velocity, and acceleration transducer inputs. Input type is configured via the Rack Configuration Software — no hardware modification required.
Q: Can this module replace a 3500/42M in an existing rack?
A: The 3500/42-01-00 and 3500/42M occupy the same rack slot and share the same backplane connector. Compatibility depends on firmware version and rack revision — contact us with your rack serial number for confirmation.
Q: What is the difference between part numbers 176449-02 and 128229-01?
A: 176449-02 is the main I/O circuit board; 128229-01 is the mating terminal block / I/O connector. Both are required for a complete, field-wirable assembly.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 12-month warranty on all tested and reconditioned units. New OEM units carry the original manufacturer warranty.
Q: Can you supply the matching Proximitor sensors and cables?
A: Yes. We stock a broad range of Bently Nevada 3300 and 3500 series transducers, extension cables, and rack accessories. Request a complete BOM quote.
