Bently Nevada 3500/22M (Part No. 138607-01)

The Bently Nevada 3500/22M 138607-01 is a Transient Data Interface (TDI) module used in the Bently Nevada 3500 Series Machinery Protection System.
It acts as the communication and data-acquisition interface between the 3500 monitoring rack and external software used for machinery condition monitoring and diagnostics.

Main Function

The module’s main role is to collect and transmit machinery vibration and condition data from the 3500 rack to monitoring software such as Bently Nevada System 1 Condition Monitoring Software.

It essentially performs two tasks:

Rack Interface Module (RIM) function – communicates with all modules inside the 3500 rack.

Transient data acquisition – captures dynamic waveform data from vibration monitors for advanced analysis.
