Bently Nevada 3500/22M 161580-01 Transient Data Interface Module

Product Introduction

The Bently Nevada 3500/22M (Part No. 161580-01) is an advanced Transient Data Interface (TDI) Module used within the Bently Nevada 3500 Machinery Protection System. It serves as both the Rack Interface Module (RIM) and a data communication gateway, providing high-speed transfer of both steady-state and transient machinery data to the System 1® Condition Monitoring software.

This module enables powerful event diagnostics by capturing high-resolution data during critical events like startups, shutdowns, and machine trips. As the enhanced version of the 3500/22, the 22M supports Ethernet communications, advanced configuration management, and improved diagnostic tools, all from Slot 1 of the rack.

Its combination of real-time data acquisition, support for redundant configurations, and hot-swappable design makes the 3500/22M ideal for high-reliability and mission-critical industrial environments.

Technical Specifications

Applications

The 3500/22M TDI Module is widely used in advanced machinery monitoring systems, particularly in industries requiring high availability and condition-based maintenance strategies:

• Turbomachinery (Gas and Steam Turbines)
  For capturing dynamic machine behavior during operation.

• Compressors and Expanders
  Real-time monitoring during pressure surges and load changes.

• Industrial Generators and Motors
  For vibration diagnostics and alignment checks.

• Critical Pumps and Blowers
  Enables early detection of faults like cavitation or imbalance.

• Refineries and Petrochemical Facilities
  For asset protection in hazardous or continuous operations.

• Power Generation Plants
  Seamless integration with DCS and plant automation systems.

Product Advantages

• All-in-One Communication Solution
  Combines configuration control and transient data interface in one module, saving space and simplifying setup.

• System 1® Integration
  Provides reliable data transfer to condition monitoring software for detailed diagnostics.

• Enhanced Memory and Performance
  Compared to 3500/22, the 22M offers improved memory and processor capacity for faster data handling.

• Supports Redundant Operation
  Dual TDIs ensure fault tolerance and continuous operation in critical systems.

• Modbus TCP/IP and Serial Support
  Flexible communication options for integration with control systems and SCADA networks.

• User-Friendly Diagnostics
  Onboard LED indicators allow quick status verification and troubleshooting.

• Hot-Swappable Design
  Field serviceable without shutting down the entire rack.
