Description

The Bently Nevada 3500/22-01-02-00 acts as the primary communication and data collection gateway for the 3500 machinery protection system. This 3500 Series Transient Data Interface Module (TDI) forms a vital bridge between the operational hardware rack and host analysis software platforms, including System 1 Condition Monitoring and Diagnostic software alongside standard 3500 System Configuration configurations. By consolidating the core interface capabilities of a traditional 3500/20 Rack Interface Module (RIM) with the high-bandwidth telemetry processing of an external communication processor, the unit delivers integrated data infrastructure. It interfaces with M series monitoring modules to continuously gather steady-state and high-density transient dynamic waveform recordings, routing them cleanly via a dedicated Ethernet connection. The module provides standard static data capture out of the box, with options to unlock expanded high-resolution wave capture utilizing a specialized enabling disk. Installed directly into the dedicated control slot next to the power supplies, it manages rack-wide operations without interfering with the independent, safety-critical protection loops of individual machinery monitors.

Features

• Integrated Communications Framework: Merges standard rack interface module duties with communication processor architectures into a single slot footprint.
• Simultaneous Waveform Telemetry: Captures both synchronous and asynchronous dynamic waveform recordings across up to 48 distinct monitoring channels.
• Dedicated Data Management: Buffers comprehensive pre-alarm and post-alarm histories, logging static data points at 100 millisecond intervals during critical machine events.
• Fiber Optic Network Support: Uses a full-duplex multimode 100Base-FX fiber interface to maintain optical isolation and extend field data distances.
• Non-Interfering Operation: Functions outside the hardware trip protection loop to prevent network management faults from compromising machinery shutdown safety.
• Hardware Mode Security: Employs a physical front-panel keylock switch to secure configuration states and eliminate remote tampering.

Applications

• Real-Time Transient Shaft Orbit and Waveform Capture during Machine Startup and Coastdown 
• Machinery Condition Monitoring and Predictive Diagnostics with System 1 Software Networks 
• Multi-Channel Vibration Data Acquisition on Steam Turbines and High-Speed Compressors 
• High-Speed Counter and Keyphasor Event Timing Coordination Across the Control Rack

Installation Guidelines

• Module Slot Placement: The TDI main processor module must always be slid into Slot 1 of the 3500 system rack, situated directly adjacent to the primary power supply modules.
• Upgrade Precedence Advisory: When upgrading an old rack from a 3500/20 RIM module, you must extract the old RIM processor and its companion RIM I/O card before sliding the new TDI components into place. Leaving legacy RIM I/O cards inside the backplane during TDI startup will cause physical circuit damage to the new TDI processor.
• Signal Grounding Configuration: To tie the Signal Common loop to an instrument ground via the 2-pin connector on the rear I/O card, you must slide the selector toggle located on the side of the Power Input Module (PIM) toward the "HP" arrow. This effectively isolates signal common loops from safety chassis grounds.
• USB Isolation Caution: The designated USB download cable (part number 123M4610) must be deployed for configuration connection to maintain structural electrical isolation between the main rack chassis and your programming PC. Ensure the connected laptop is operating entirely on battery power (not plugged into grid mains) to block ground loops.
