Product Introduction
Bently Nevada 3500/22M 288055-01 is a Transient Data Interface module for the Bently Nevada 3500 machinery protection system. The 3500/22M 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 288055-01 number refers to the standard TDI front panel assembly. It is typically paired with the 146031-01 10Base-T/100Base-TX Ethernet I/O rear panel, and may be supplied with a USB cable for local configuration. The module is installed in Slot 1 of the 3500 rack, adjacent to the power supply slots.
The 3500/22M 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.
Some third-party listings describe 3500/22M 288055-01 as an eddy-current sensor, displacement module, or relay card. Those descriptions are incorrect. 288055-01 is the TDI front panel assembly for the 3500/22M interface module, not a sensor, monitor, or relay module.

Note: The 3500/22M TDI function, 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 3500/22M documentation.
Quality Control Process (DYNAMIC GENERATION)
- Label and part number verification. We confirm the module reads 3500/22M and the front panel P/N is 288055-01.
- TDI function verification. We confirm it is a Transient Data Interface module and not mislabeled as a sensor, monitor, relay, or communication gateway module.
- Rear panel check. We verify the installed I/O rear panel matches the expected 146031-01 Ethernet or specified variant.
- Physical inspection. The front panel, Ethernet port, RS-232 port, configuration key lock, LEDs, and mounting hardware are checked for damage or corrosion.
- 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. 3500/22M 288055-01 is a TDI interface module, not an eddy-current probe, 3500/42M monitor, or relay card.
❗ Verify the rear panel P/N. The 288055-01 front panel may be paired with 146031-01 (copper Ethernet) or 146031-02 (fiber Ethernet); confirm the rear panel matches the existing installation.
❗ Confirm Slot 1 placement. The 3500/22M 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.
❗ Confirm dynamic data enable disk. Transient waveform channel capacity depends on the installed dynamic data enable disk; verify channel licensing before replacement.
❗ 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.
