Bently Nevada 3500/22M (P/N 288055-01) – Transient Data Interface for 3500 Machinery Protection Racks

The Bently Nevada 3500/22M Transient Data Interface (TDI) is the communications and high-resolution data hub for a 3500 rack. From my experience, it’s the piece that lets you capture startup/shutdown waveforms, trips, and other transient events without bolting on extra hardware. If you’re running turbines, compressors, or critical pumps and relying on System 1 software for condition monitoring, this is typically the module that makes the data flow clean and fast.

Key Features

• Transient and steady-state data capture – Records high-resolution dynamic waveforms during startups, shutdowns, and alarm events, which seems to be the quickest way to troubleshoot real trips.
• Rack-wide communications – Serves as the communication processor for the entire 3500 rack, aggregating status, alarms, and channel data.
• Ethernet connectivity – Provides 10/100Base‑T for configuration and data streaming to System 1, reducing the need for additional gateways in many cases.
• Backplane integration – No field wiring to the TDI itself; it pulls data directly from installed 3500 monitors over the rack backplane.
• Event-driven recording – Captures trend and waveform data on specific triggers (e.g., alarm condition), which typically cuts the time-to-diagnosis after a shutdown.
• Service-friendly design – Front-removable module; swap without disturbing any transducer terminations.

Technical Specifications

Application Fields

You might notice that this module shows up wherever machinery protection is mission‑critical. Common deployments include:

• Oil & gas – compressors, gas turbines, turboexpanders
• Power generation – steam turbines, generator trains, large fans
• Petrochemical & refining – process pumps, blowers, extruders
• Metals, pulp & paper, mining – high-value rotating assets where transient capture speeds root-cause analysis

A maintenance lead at a gas processing plant told us the TDI saved hours during a hot restart: they pulled the trip waveform straight into System 1 and isolated a rub event without a second shutdown.

Advantages & Value

• Reliability – Designed for continuous service in the 3500 ecosystem; fewer standalone boxes means fewer failure points.
• Compatibility – Works across 3500 monitors via the backplane and streams to System 1; no custom wiring.
• Lower lifecycle cost – Event-driven capture reduces unplanned outages and shortens diagnosis time.
• Service & support – Widely supported in the field; spares and firmware support are typically straightforward to manage.

Installation & Maintenance

• Mounting – Install in the designated TDI slot of the 3500 rack; ensure the rack is properly secured in a cabinet or panel with adequate ventilation.
• Environment – Keep the enclosure clean and dry; avoid conductive dust; maintain temperature within the 3500 system rating.
• Wiring – No field transducers land on the TDI. Use quality shielded Ethernet to the plant network or System 1 server; segregate from high-noise power cables.
• Safety – De-energize the rack or follow live-swap procedures per the official manual; observe ESD precautions.
• Routine care – Periodically verify network link status, back up rack configuration, review event logs, and apply approved firmware updates during planned outages.

Quality & Certifications

• Typically CE marked and UL/cUL recognized for industrial use
• Manufacturer quality system commonly certified to ISO 9001
• Designed to meet RoHS guidelines in most markets
• Warranty: 365 days
