The 3500/40M (Part Number: 3500/40-02-01) is a high-density 4-channel Proximitor monitor module designed for integration with the Bently Nevada 3500 machinery protection system. This module provides advanced signal conditioning and processing for critical machinery parameters, including radial vibration, axial thrust, differential expansion, and shaft eccentricity.
Designed for installation in a 3500 series rack, this configuration features an I/O module with external terminations, allowing easier wiring access and simplified maintenance in industrial control cabinets. Its flexible architecture enables precise monitoring of rotating machinery, supporting predictive maintenance and automated protection strategies for high-value equipment.

The 3500/40M monitor plays a crucial role in protecting industrial rotating machinery by detecting early indicators of mechanical faults before they escalate into severe equipment damage. The module processes raw signals from proximity transducers and compares them against user-defined alarm thresholds, providing operators with immediate alerts when abnormal vibration or shaft displacement is detected.
The external termination design (02 option) simplifies field wiring and troubleshooting, making it particularly useful in complex retrofits, large control cabinets, or installations with remote junction boxes.
What is the difference between the 02 and 03 I/O modules for this monitor?
The 02 module uses external terminations, which simplify field wiring and maintenance. The 03 module includes internal safety barriers and internal terminations, designed for specialized hazardous area installations.
Can this module measure both vibration and position simultaneously?
Yes. Each of the four channels can be independently configured to monitor different parameters such as radial vibration, axial position, differential expansion, or eccentricity.
Is this module compatible with older proximity probe systems?
Yes. The monitor is designed to work with standard Bently Nevada eddy-current proximity transducer systems, including both legacy and current-generation probes.
