The Bently Nevada 3500/22M 138607-01 Standard Transient Data Interface (TDI) Module is a communication and data acquisition module designed for the Bently Nevada 3500 Machinery Protection System. It provides the interface between the 3500 rack monitoring system and machinery management software such as System 1®, enabling continuous collection, transmission, and analysis of machinery condition data.
The 3500/22M integrates the functions of the 3500/20 Rack Interface Module (RIM) with communication processor capabilities, allowing the system to collect steady-state values and transient waveform data from compatible M-Series monitoring modules and transfer information through Ethernet communication to host systems.

The Bently Nevada 3500/22M 138607-01 is a Standard Transient Data Interface Module used as the communication gateway of the Bently Nevada 3500 monitoring platform.
The module performs the following functions:
Collects machinery monitoring data from 3500 monitoring modules
Transfers steady-state and transient dynamic data
Provides communication between the 3500 rack and diagnostic software
Supports rack configuration and system monitoring
Enables advanced machinery condition analysis
The TDI operates in the dedicated Rack Interface Module (RIM) slot of a 3500 rack and works with M-Series monitors such as:
3500/40M Proximitor Monitor
3500/42M Proximitor/Seismic Monitor
Other compatible 3500 monitoring modules
It continuously collects machine operating information and transfers data through Ethernet communication to monitoring software platforms for fault diagnosis, trending analysis, and predictive maintenance.
