3500/22M Transient Data Interface (TDI)

Overview The 3500/22M Transient Data Interface (TDI) provides the primary interface between a Bently Nevada 3500 machinery protection rack and System 1 condition-monitoring software. Installed in the left side of the rack, the TDI collects static values, dynamic overall data, and high-resolution transient waveforms from installed modules, timestamps events, and serves them over Ethernet for diagnostics, reporting, and long-term analysis—without interrupting protection functions. Highlights Rack controller & interface for the 3500 system (supersedes legacy RIM). Transient data capture for startups, shutdowns, trips, and process upsets. Ethernet (10/100Base-T) connection to System 1; supports remote configuration & data collection.* Combines protection condition monitoring: no separate transient card needed. Time-stamped event/alarm logs for audit and troubleshooting. Hot-swappable module with front status LEDs for health/communication. *Use per site standard; exact protocol & options depend on System 1 version and rack configuration. Communications & I/O Rear I/O module for Ethernet and rack communications (ordered to match your rack). Interfaces with installed 3500 monitors (e.g., 3500/40M, /42M, /44M, /50, /60, etc.) to acquire data. Supports Keyphasor®-based diagnostics when present in the rack. Compatibility & Ordering Notes Fits Bently Nevada 3500 racks with appropriate power supplies and monitors. Replaces RIM (3500/20) in most applications. Typical order: 3500/22M TDI module matching TDI I/O module (sold separately). For firmware/System 1 compatibility, share your rack part list and software version. Typical Applications Turbomachinery (compressors, steam/gas turbines), large motors/generators Critical pumps and fans in oil & gas, power, petrochem, mining Any installation needing transient waveform capture with 3500 protection What’s in the Box (this listing) 3500/22M TDI module (spare/replacement). Note: I/O module, rack, monitors, and cabling are not included unless stated on the quote. Helpful Links (internal) Category: Vibration Inquiry / RFQ: click FAQ  Q1: What does the 3500/22M TDI do? It controls rack communications and streams static, dynamic, and transient data from 3500 monitors to System 1 over Ethernet. Q2: Does the TDI affect protection functions? No. Protection logic remains in the monitor modules; the TDI handles data & comms. Q3: Is the rear I/O included? Typically no. Order the TDI I/O module separately to match your rack and cabling. Q4: Can I upgrade from RIM (3500/20)? In most systems, yes. Share your rack configuration and System 1 version to verify. Q5: What about Keyphasor® and transient capture? When Keyphasor® and relevant monitors are installed, the TDI enables waveform/transient capture for advanced diagnosis in System 1. Call to Action Need to confirm firmware and System 1 compatibility?
