Description
Description
The Bently Nevada 3500/22M Transient Data Interface (TDI) module, part number 161580-01, serves as the primary gateway for the 3500 Machinery Protection System. It functions as the interface between the 3500 rack and various software applications, including Bently Nevada's System 1 condition monitoring software. The TDI module combines the capabilities of the legacy 3500/20 Rack Interface Module (RIM) with high-speed data collection, supporting both steady-state and transient waveform data capture for comprehensive machinery diagnostics.
Features
- Integrates rack interface and communication processor functions into a single module.
- Provides Ethernet connectivity for seamless integration with System 1 software.
- Supports both steady-state and transient data collection for advanced diagnostics.
- Equipped with a front-panel USB port for local configuration and maintenance.
- Includes a dedicated I/O module with an OK relay for system health monitoring.
- Features a configuration keylock switch to prevent unauthorized changes to rack settings.
- Supports up to 127 rack addresses for large-scale system deployments.
Applications
The 3500/22M TDI is essential for critical machinery protection and condition monitoring in industrial environments, including power generation, oil and gas, petrochemical, and heavy manufacturing. It is used to monitor rotating equipment such as turbines, compressors, pumps, and motors, ensuring early detection of mechanical faults through transient data analysis.

FAQ
What is the primary function of the 3500/22M module?
The 3500/22M acts as the communication interface between the 3500 rack and external monitoring software, while also managing the collection of transient and steady-state data from the rack's monitor modules.
Can this module be used in place of a 3500/20 RIM?
Yes, the 3500/22M TDI is designed to replace the 3500/20 Rack Interface Module, providing enhanced data collection capabilities and integrated communication features.
How is the module configured?
Configuration is performed via the 3500 Rack Configuration Software, typically connected through the front-panel USB port or the rear Ethernet port, with the physical keylock switch set to the PROGRAM position.
