Bently Nevada 3500/22-01-01-01 138607-01 Transient Data Interface Module

Overview

The 3500/22-01-01-01 138607-01 Transient Data Interface module is a core communication and data acquisition component within the Bently Nevada 3500 Series machinery protection system. It performs both rack interface and data handling functions, allowing seamless interaction between the monitoring rack and external software platforms for advanced diagnostics and condition monitoring.

Core Functionality

• Integrates rack interface and communication processing in a single module

• Enables continuous acquisition of both steady-state parameters and transient waveform data

• Transfers monitoring data to host systems via Ethernet connection

• Acts as the primary interface between the 3500 rack and System 1™ software environment

Technical Specifications

• Model: 3500/22-01-01-01 138607-01

• Module Type: Transient Data Interface (TDI)

• Rack Position: Slot 1 (adjacent to power supply)

• Communication Interface: Ethernet (10/100Base-T)

• Compatible Systems:

• Bently Nevada 3500 Series racks

• M-series monitor modules (e.g., 3500/40M, 3500/42M)

Data Acquisition Performance

• Data Types: Static values and dynamic waveform capture

• Sampling Capability: Up to high-resolution transient waveform acquisition (system-dependent)

• Resolution: 16-bit data processing (aligned with monitor modules)

• Bandwidth Support: Typically up to 20 kHz depending on connected monitor modules

System Integration

• Software Compatibility:

• System 1™ Condition Monitoring Platform

• 3500 Rack Configuration Software

• Data Transfer: Continuous streaming of condition monitoring data

Environmental Specifications

• Operating Temperature: -40°C to +85°C

• Relative Humidity: 5% to 95% (non-condensing)

Mechanical Characteristics

• Mounting: 3500 rack-mounted module (not standalone 19-inch equipment)

Important Technical Notes

• This module replaces the traditional Rack Interface Module (RIM) in systems requiring transient data capture

• It must be installed in the designated first slot; incorrect placement will prevent system operation

• Each 3500 rack requires one interface module (either RIM or TDI) to function

Variant Information

• 138607-01: Standard TDI module

• 138607-02: TMR-compatible version for Triple Modular Redundancy systems

Key Features

• Integrated Architecture
  Combines communication and rack interface roles, reducing module count and simplifying system design

• Ethernet-Based Communication
  Provides reliable, high-speed data transfer to monitoring and asset management systems

• System-Level Compatibility
  Fully aligned with Bently Nevada 3500 ecosystem and System 1™ software

• Redundancy Options
  Available in TMR configurations for high-availability applications

Typical Applications

• Steam and gas turbine protection systems

• Centrifugal compressors and pumps

• Critical rotating machinery in oil & gas and petrochemical facilities

• Power generation plants requiring predictive maintenance strategies

FAQ

Q: Is this module mandatory for a 3500 rack?
A: Yes, each rack requires either a TDI or a RIM module to enable communication and operation.

Q: What is the advantage of using a TDI instead of a RIM?
A: The TDI adds transient waveform data collection capability, which is essential for advanced diagnostics and analysis.

Q: Does this module directly accept sensor inputs?
A: No, signal inputs are handled by dedicated monitor modules. The TDI collects and transmits processed data from those modules.

Q: Can it be used in redundant systems?
A: Yes, but a dedicated TMR version (138607-02) must be selected for redundancy applications.
