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

Product Description

The 3500/22M 138607-01 Transient Data Interface (TDI) module from Bently Nevada is a key communication and data acquisition component within the 3500 Machinery Protection System. It integrates rack interface functionality with advanced dynamic data capture, enabling high-resolution monitoring of machine conditions.

Positioned directly beside the power supply modules within a 3500 rack, this unit acts as the primary gateway between the monitoring system and external software platforms such as System 1. It supports continuous acquisition of both steady-state parameters and transient waveform data, which is essential for detailed vibration analysis and machinery diagnostics.

Functional Characteristics

The 3500/22M (138607-01) consolidates two essential roles within the 3500 system architecture: communication management and transient data acquisition. By merging these functions, it reduces system complexity while enabling continuous monitoring and event-driven analysis.

Its ability to capture waveform data during transient conditions—such as startup, shutdown, or fault events—provides engineers with deeper insight into machinery behavior beyond standard steady-state measurements.

Application Areas

• Turbomachinery monitoring in oil & gas facilities

• Power generation equipment (steam and gas turbines)

• Critical rotating machinery protection systems

• Condition-based maintenance and predictive diagnostics

FAQ

Q: What distinguishes the 3500/22M from the 3500/20 module?
A: The 3500/22M integrates transient data capture capabilities, whereas the 3500/20 primarily provides rack interface functions without advanced waveform acquisition.

Q: Is this module required in every 3500 rack?
A: Yes, one interface module (such as the 3500/22M) is required to enable communication between the rack and external systems.

Q: What type of data can be analyzed using this module?
A: Both static condition data and high-resolution dynamic waveform data, especially useful for vibration and fault analysis.

Q: Does it support modern monitoring platforms?
A: It is optimized for Bently Nevada System 1 and remains widely used in installed systems, though newer platforms may offer enhanced capabilities.
