Product Introduction
Bently Nevada 3500/22-01-01-00 is a Transient Data Interface module for the Bently Nevada 3500 machinery protection system. The 3500/22 TDI combines the functions of a 3500/20 Rack Interface Module with a communication processor, enabling configuration, monitoring, and transient data acquisition for the 3500 rack.
The ordering code follows the 3500/22-AXX-BXX-CXX format: “01” in position A indicates a standard TDI module (non-TMR); “01” in position B indicates a 10Base-T/100Base-TX Ethernet I/O rear panel (typically 146031-01); “00” in position C indicates no agency approval option. The module is installed in Slot 1 of the 3500 rack, adjacent to the power supply slots.
The 3500/22 communicates with Bently Nevada System 1 software and 3500 Rack Configuration Software via Ethernet TCP/IP or RS-232. It collects steady-state and transient waveform data from M-series monitors such as 3500/40M, 3500/42M, and 3500/44M, and supports alarm-triggered and speed-triggered transient recording. The module performs communication and diagnostic functions but does not participate in protection tripping logic.
The 3500/22-01-01-00 is the predecessor to the 3500/22M family (e.g., 288055-01). Both belong to the same TDI product line and share the same core function, but the 22M generation introduced hardware updates such as a USB-B configuration port. The -00 and -01 approval suffix variants are functionally compatible and can typically be interchanged in existing racks.
Some third-party listings may describe 3500/22 as a sensor, monitor, or relay module. Those descriptions are incorrect. 3500/22-01-01-00 is a TDI interface module and should not be substituted for 3500/42M, 3500/32, 3500/25, or other functional modules.

Note: The 01-01-00 configuration, Slot 1 placement, Ethernet/RS-232 interfaces, and System 1 integration are documented for this module family. The exact firmware revision, dynamic data enable disk configuration, transient channel capacity, and approval markings should be verified from the physical label and Bently Nevada 3500/22 documentation.
Quality Control Process (DYNAMIC GENERATION)
- Label and part number verification. We confirm the module reads 3500/22-01-01-00 and matches the 3500/22 standard TDI family.
- Configuration code check. We verify 01-01-00 corresponds to standard TDI, 10/100Base-TX Ethernet rear panel, and no approval option.
- Rear panel check. We verify the installed I/O rear panel matches the expected 146031-01 Ethernet variant.
- Physical inspection. The front panel, Ethernet port, RS-232 port, configuration key lock, LEDs, and mounting hardware are checked for damage or corrosion.
- Function family verification. We confirm it is not mislabeled as a sensor, monitor, relay, or communication gateway module.
- Final packaging. After inspection, the module is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Do not confuse it with a sensor or monitor module. 3500/22-01-01-00 is a TDI interface module, not an eddy-current probe, 3500/42M monitor, or relay card.
❗ Verify the rear panel P/N. The -01 configuration corresponds to 146031-01 (copper Ethernet). Do not substitute with 146031-02 (fiber Ethernet) without verifying rack compatibility.
❗ Confirm Slot 1 placement. The 3500/22 TDI must be installed in Slot 1 of the 3500 rack; incorrect slot placement will prevent proper rack communication.
❗ Check configuration key lock position. Ensure the key lock is set to RUN after configuration to prevent unintended changes.
❗ Verify firmware and software compatibility. The TDI firmware must be compatible with the installed System 1 and 3500 Rack Configuration Software versions. When replacing a 3500/22M with a 3500/22 or vice versa, confirm firmware compatibility with the existing rack.
❗ Confirm dynamic data enable disk. Transient waveform channel capacity depends on the installed dynamic data enable disk; verify channel licensing before replacement.
❗ Check the 00 approval suffix. The “00” suffix means no agency approval. If the installation requires CSA/NRTL/C certification, a -01 approval variant may be needed instead.
❗ Handle as ESD-sensitive equipment. Use anti-static handling procedures during removal, installation, and storage.
Keep these in mind and you’ll cut 90% of rework time.
