Description
The Bently Nevada 3500/22M Transient Data Interface (TDI) serves as the primary communication gateway between the 3500 Machinery Protection System and external software platforms, including System 1 Condition Monitoring and Diagnostic software. By integrating the functionality of a 3500/20 Rack Interface Module (RIM) with the high-speed data collection capabilities of a communication processor, the TDI enables continuous monitoring of steady-state and transient dynamic waveform data.
The 138607-01 is the standard version of the TDI module, designed to occupy the dedicated slot (Slot 1) immediately adjacent to the power supplies in a 3500 rack. It facilitates Ethernet-based communication to host software for advanced machinery diagnostics.
Features
- Integrates 3500/20 RIM functionality with advanced communication processing.
- Supports continuous collection of steady-state and transient (waveform) data.
- Enables high-resolution diagnostic analysis via System 1 software.
- Features a physical keylock for secure switching between RUN and PROGRAM modes.
- Standard static data capture with optional dynamic data capability.
Applications
-
Power Generation: Monitoring of steam, gas, and hydro turbines for early-stage mechanical fault detection.
-
Oil & Gas: Critical protection and analysis for high-value pumps, compressors, and motors in refineries.
-
Heavy Manufacturing: Vibration monitoring for large rotating equipment in steel and paper mills.
-
Predictive Maintenance: Facilitates long-term trend analysis and post-event failure investigation.

Installation Guidelines
-
Slot Placement: The TDI must be installed in Slot 1 of the 3500 rack, directly next to the power supply modules.
-
Handling: Use standard ESD precautions when handling the module to prevent damage to sensitive internal circuitry.
-
Power: Ensure the rack power is stable; the module is hot-swappable in most configurations, but verify system requirements before removal.
-
Configuration: Use the front-panel serial port for local configuration. Ensure the keylock is set to the appropriate mode (RUN/PROGRAM) during operation.
-
Cabling: Use shielded Ethernet cabling for the host software connection to minimize EMI interference in industrial environments.
FAQ
What is the function of the 3500/22M 138607-01?
It acts as the interface between the 3500 rack and System 1 software, capturing both steady-state and transient vibration data for detailed machinery health analysis.
Is this module still in production?
The 138607-01 is a legacy version and has been superseded by the 288055-01. The newer version replaces the serial port with a USB-B interface for easier connectivity.
Can this be used in TMR systems?
The 138607-01 is the standard version. For Triple Modular Redundant (TMR) applications, a specific TMR version of the TDI is required to perform monitor channel comparison.
