Bently Nevada 140734-03 3500/42M Internal I/O Module

Product Description

The Bently Nevada 140734-03 is a 4-channel I/O module for the 3500/42M Proximitor Seismic Monitor. Designed for vibration, position, and speed monitoring, it provides high-fidelity signal capture from Proximitor probes, Velomitors, or accelerometers. The internal termination variant allows direct field wiring to the 3500 rack, reducing installation complexity while maintaining signal integrity.

Key Features

• 4 independent vibration or position input channels

• Internal Euro-style terminations for direct wiring

• Supports Proximitor, Velomitor, and standard accelerometer sensors

• Galvanic isolation to prevent ground loops and interference

• High-fidelity pass-through for DC and AC dynamic signals

• Industrial operation: -30°C to +65°C

• Class I, Division 2 compliant when properly installed

Applications

• Radial vibration monitoring for turbine unbalance or misalignment

• Axial position tracking for thrust bearings

• Eccentricity and thermal growth measurements

• Casing vibration and high-frequency bearing diagnostics

FAQ

Q: How does the -03 differ from -01 or -02?
A: The -03 has internal terminations, allowing direct field wiring. The -01 uses external terminals, and the -02 is for TMR configurations.

Q: Can it handle mixed sensor types?
A: Yes, with the 3500/42M configured per channel, it can process proximity and seismic inputs simultaneously.
