Bently Nevada 3500/22 Transient Data Interface Module

Product Introduction

The Bently Nevada 3500/22 Transient Data Interface (TDI) is a key communication and configuration module within the Bently Nevada 3500 Series machinery protection system. Designed to provide both steady-state and transient data, the TDI integrates the functionality of a traditional Rack Interface Module (RIM) with advanced communication capabilities.

Installed in slot 1 of the 3500 rack, the 3500/22 serves as the communication gateway between the rack and Bently Nevada’s System 1® software platform, enabling high-resolution data acquisition and detailed condition monitoring for rotating machinery. With its ability to capture dynamic (transient) data during machine startup, shutdown, or process upsets, the TDI plays a critical role in diagnostics, root cause analysis, and predictive maintenance programs.

The TDI supports standard communication protocols and allows seamless interaction with other modules in the 3500 rack. It is compatible with Ethernet communication, making it ideal for integration into modern control systems and remote monitoring environments.

Technical Specifications

Applications

The 3500/22 TDI is used in a wide range of critical rotating machinery monitoring applications where detailed, high-resolution data is necessary:

• Gas and Steam Turbines – For capturing startup and shutdown transients.

• Compressors and Expanders – Monitoring dynamic behavior under load conditions.

• Large Electric Motors – Vibration analysis and thermal cycling assessment.

• Industrial Fans and Pumps – Real-time performance diagnostics.

• Refineries and Petrochemical Plants – High-fidelity monitoring during process events.

• Power Plants and Utilities – Integration with DCS for plant-wide reliability.

Product Advantages

• Transient and Steady-State Data Collection
  Enables high-speed capture of vibration, position, and dynamic data for deep diagnostic capability.

• System 1® Integration
  Seamlessly connects to GE’s System 1® software for real-time asset condition monitoring.

• Rack-Wide Configuration Control
  Manages system configuration, communication, and alarm logging across all 3500 modules.

• Supports Redundant Configuration
  Dual TDIs can be used for backup to ensure continuous data flow and system communication.

• Multi-Protocol Communication
  Supports Ethernet and serial protocols for flexibility in industrial networks.

• LED Status Monitoring
  Simplifies diagnostics through onboard LED indicators for network, communication, and module health.
