Product Overview

The Bently Nevada 2155/40 TDISecure is a high-performance, multi-channel communication processor designed for advanced machinery condition monitoring.

It provides a secure, high-fidelity data acquisition bridge between Bently Nevada machinery protection systems and System 1 optimization/diagnostic software. Unlike standard interfaces, TDISecure isolates data collection from protection logic, offering a cost-effective cybersecurity solution that eliminates the need for external data diodes while streaming high-resolution vibration and process data.

Key Features and Benefits

  • Parallel Sampling: Synchronized acquisition of 24 vibration signals for precise phase analysis and root-cause diagnostics.

  • Cybersecurity Integrity: Protects primary hardware from network-based threats while interfacing with plant networks.

  • Transient Data Collection: Automatically captures high-resolution waveform data during machine startup and shutdown.

  • Direct Sensor Power: Supplies integrated power for up to 4 Proximitor® sensors, simplifying field wiring for speed measurements.

  • Legacy Compatibility: Acts as a modern drop-in replacement for TDXnet and TDIX communication processors.


Technical FAQ

Q1: How does the TDISecure 2155/40 improve on the legacy TDXnet?
A: It provides enhanced Ethernet security, faster data processing, native integration with System 1, and more robust process input configuration options.

Q2: Can this module provide protective trip functions?
A: No. The 2155/40 is strictly for data acquisition and communication. Protective trips/alarms remain the responsibility of the primary 3500 monitoring rack, which TDISecure monitors via buffered outputs.
