The Bently Nevada 3500/22M 288055-01 serves as the primary communication gateway between the Bently Nevada 3500 Monitoring System and compatible software (System 1 Condition Monitoring and Diagnostic software). As the "intelligence hub" of the rack, the 3500/22M (Transient Data Interface or TDI) collects static and dynamic (transient) waveform data from the monitoring modules, allowing for sophisticated vibration analysis and machinery diagnostics. It bridges the gap between basic machinery protection and advanced predictive maintenance by capturing critical data during machine startups, shutdowns, and alarm events.
The 288055-01 is the standard Ethernet-compatible TDI designed for high-speed data transmission and seamless rack integration.

The part number 3500/22-01-01-02 (utilizing the 288055-01 main board) breaks down as follows to define the specific hardware configuration:
3500/22M: The base model designation for the Enhanced Transient Data Interface. The "M" denotes enhanced capabilities over the original 3500/22.
01 (Option 1): Specifies the Standard I/O Module. This determines the physical interface at the rear of the rack, typically utilizing the 10/100 Base-T Ethernet connection.
01 (Option 2): Indicates Ethernet (10/100 Base-T) Connectivity. This is the modern standard for high-bandwidth data offloading to System 1.
02 (Option 3): Defines the Agency Approval Option. Specifically, this often denotes Multi-Agency Approvals (ATEX/IECEx/CSA) for use in Class I, Division 2 or Zone 2 hazardous areas.
288055-01: This is the specific manufacturing part number for the main TDI circuit board assembly.
To ensure optimal performance and prevent data corruption, follow these installation standards:
Slot Placement: The 3500/22M TDI must be installed in the first slot (leftmost side, immediately next to the Power Supplies) of the 3500 rack.
I/O Module Alignment: Ensure the rear I/O module (Ethernet/RS232) is perfectly aligned with the front-facing TDI processor. Misalignment during "hot-swapping" can damage the backplane connectors.
Grounding: The rack must be properly grounded to the plant's instrumentation earth. Use shielded Cat5e or Cat6 cables for Ethernet connections to minimize EMI/RFI interference from heavy machinery.
Configuration: Connect via the front RS232 port using the 3500 Rack Configuration Software to assign an IP address before connecting to the plant network.
Q: Can I upgrade my old 3500/22 to the 3500/22M 288055-01?
A: Yes. The 3500/22M is backward compatible with 3500 racks; however, it requires Rack Configuration Software version 4.0 or later and may require a firmware update of other modules in the rack.
Q: Does this module support "Hot Swapping"?
A: Yes, the 3500/22M is designed to be removed or installed while the rack is powered. Note that machinery protection remains active, but data communication to System 1 will be interrupted during the swap.
Q: What is the primary difference between the 3500/22M and the 3500/25?
A: The 3500/22M (TDI) is the communication gateway for the entire rack, whereas the 3500/25 is a Keyphasor module used specifically for providing timing signals to the other modules.
