Bently Nevada 135489-02 3500/42M Proximitor Seismic Monitor I/O Module

The Bently Nevada 135489-02 is an I/O interface module used with the 3500/42M Proximitor Seismic Monitor.

It provides the connection between field sensors and the monitoring module, allowing the 3500 system to process machinery condition signals such as:

• Radial vibration

• Shaft displacement

• Bearing vibration

• Velocity vibration

• Acceleration signals

The module is configured with:

• 2 channels for Proximitor / acceleration inputs

• 2 channels for Velomitor velocity inputs

The internal barrier design provides additional protection for applications requiring hazardous-area sensor installation. The internal termination design simplifies wiring by integrating connection points directly into the I/O module assembly.

The 135489-02 works together with the 3500/42M monitor to provide programmable alarm monitoring, vibration measurement, and machinery protection functions for rotating equipment.
