The 3500/22-01-01-01 is a complete Transient Data Interface (TDI) assembly for the 3500 Machinery Protection System developed by Bently Nevada.
This configuration includes a standard TDI module paired with a high-speed Ethernet I/O interface, enabling seamless communication between the monitoring rack and external diagnostic software such as System 1.
The module captures both steady-state and transient waveform data, providing comprehensive machinery health visibility during critical operating phases including startup, coast-down, and alarm events. This makes it essential for predictive maintenance and advanced root cause diagnostics.

The 3500/22-01-01-01 is designed to replace legacy Rack Interface Modules (RIM), offering significantly improved data throughput and diagnostic capability.
It supports simultaneous transmission of:
Static process data (gap voltage, overall vibration levels)
Dynamic waveform data (orbits, timebase signals)
When integrated with System 1 software, engineers can perform advanced visualization and diagnostics such as:
Orbit plots
Bode plots
Timebase analysis
Spectrum and cascade diagrams
These capabilities help detect early-stage machinery faults such as shaft cracks, bearing wear, rotor imbalance, and misalignment conditions.
Q1: Does the 3500/22-01-01-01 support Modbus communication?
A: Yes. With appropriate configuration and supporting I/O hardware, the TDI can transmit rack data using Modbus over Ethernet for integration with PLC or DCS systems.
Q2: Is the CSA/NRTL/C certification valid for hazardous environments?
A: Yes. The 01 Agency Approval option meets safety standards for Class I, Division 2 hazardous industrial locations in North America when installed according to manufacturer specifications.
