Bently Nevada 3500/72M 140482-01 Prox/Velom I/O Module

The 3500/72M 140482-01 is an I/O module with external terminations used within the Bently Nevada 3500 Machinery Protection System.

This module is designed to provide a convenient interface between field sensors and the main monitoring module. It supports connection of transducer signals and allows easier installation, maintenance, and troubleshooting through external terminal access.

The 140482-01 is associated with the 3500/72M Recip Rod Position Monitor configuration and provides the external termination interface required for field wiring. The 3500/72M monitor accepts input from proximity transducers, conditions the signals, generates dynamic and static position measurements, and compares measured values against user-configurable alarm limits.

Typical monitored parameters include:

• Rod position

• Rod drop

• Hyper-compressor position measurement

The design supports industrial applications requiring continuous machinery protection and compliance with demanding compressor monitoring requirements.
