Description
The Bently Nevada 3500/22M is the primary interface between the 3500 Machinery Protection System and the System 1 management software. This TDI Module serves as the communication hub of the 3500 rack, collecting static and transient hardware data from other modules and transmitting it to external networks for advanced machinery diagnostics.
Product Introduction
The 3500/22M TDI (Transient Data Interface) replaces the legacy 3500/20 RIM (Rack Interface Module). It provides enhanced processing power and built-in Ethernet connectivity. Its core function is to capture high-resolution transient vibration data during machine startup and coast-down, which is essential for identifying mechanical faults that are not visible during steady-state operation.

Usage Instructions
- Installation: The 3500/22M must be installed in the “TDI” slot, which is the first slot (Slot 1) immediately to the right of the power supplies.
- Configuration: Connect a PC to the front USB port or the rear Ethernet port. Use the 3500 Rack Configuration Software to set the IP address and network parameters.
- Data Sync: Once configured, the TDI will automatically synchronize with all monitoring modules in the rack. Ensure the “OK” LED is solid green.
- Networking: Connect the rear Ethernet port to the plant’s condition monitoring network to enable System 1 software to pull live and historical data.
- Test Mode: Use the “TM” switch only during maintenance to prevent the relay modules from triggering during system testing.
Product Q&A
- Q: Can the 3500/22M be used to replace a 3500/20 RIM?
- A: Yes, the 3500/22M is designed to be a direct replacement for the 3500/20, though it requires an updated I/O module and configuration file adjustments.
- Q: Does this module perform machinery protection trips?
- A: No, the TDI does not perform protection logic. It only facilitates communication and data collection. Protection is handled by the individual monitor modules (e.g., 3500/42M).
- Q: Is the 3500/22M hot-swappable?
- A: Yes, the module can be replaced while the rack is powered, but communication with external software will be lost during the swap.
