BENTLY NEVADA 176449-01 3500/40M Proximitor Monitor Module

Product Overview

The Bently Nevada 176449-01 is a 3500/40M Proximitor Monitor module designed for machinery protection and condition monitoring. It accepts signals from compatible Bently Nevada proximity transducers, processes them into vibration and shaft-position measurements, and compares the results against user-configurable alarm setpoints.

Important Notes

• The correct product designation is 3500/40M Proximitor Monitor, not a generic interface module.

• This is a monitoring card, not a standalone proximity probe or a complete machinery monitoring rack.

• Compatible proximity transducers and the appropriate I/O module are required.

• Channel functions and alarm settings must be configured for the intended application.

• Verify rack compatibility, I/O termination type, part number, and product condition before ordering.
