Product Overview

The Bently Nevada 3500/22M, designated by part number 288055-02, is a sophisticated Transient Data Interface (TDI) that serves as the primary gateway between the 3500 Series machinery protection system and external diagnostic platforms. By integrating the core functions of a standard Rack Interface Module (RIM) with the high-speed processing capabilities of a communication processor, the 3500/22M enables the seamless transfer of critical machine health data to System 1™ Condition Monitoring and Configuration software.

Positioned in the first slot of the 3500 rack, the TDI acts as a bridge for M-series monitors, including the 3500/40M and 3500/42M. It facilitates the continuous acquisition of both steady-state metrics and complex dynamic waveforms. While the module is essential for data logging and system configuration, it is architecturally isolated from the critical machinery protection path, ensuring that monitoring and trip functions remain fully operational even during data transmission or software interfacing.

Technical Characteristics

• Functionality: Combines the features of a Rack Interface Module (RIM) and a TDXnet communication processor.

• Data Acquisition: Captures high-resolution transient dynamic data and steady-state waveforms.

• Network Connectivity: Features an integrated Ethernet link for high-speed data output to host systems.

• Rack Placement: Mandatory installation in Slot 1, situated immediately adjacent to the rack power supplies.

• Monitor Compatibility: Engineered to interface directly with 3500 M-series vibration and position monitors.

• Static Data: Standard capability for capturing static machine parameters.

• Dynamic Upgradability: Supports high-resolution transient data capture via an optional Channel Enabling Disk.

• System Integrity: Non-interfering design ensures that automatic machinery protection paths are not affected by TDI operations.

• Configuration Support: Serves as the localized port for 3500 System Configuration software via USB or serial connections.

• Status Monitoring: Front-panel LEDs provide real-time status for "OK," "TX/RX," and "Config" states.

Application and System Integration

The 3500/22M is fundamental for facilities implementing predictive maintenance strategies. By capturing waveform data during machine startup, coast-down, or steady-state operation, it provides the raw information necessary for advanced vibration analysis and diagnostics. This allows engineering teams to identify root causes of rotor instability, bearing wear, or misalignment before they lead to catastrophic failure.

Each 3500 chassis requires exactly one interface module—either a RIM or a TDI—to manage rack-wide functions such as clock synchronization and alarm setpoint distribution. The 288055-02 variant ensures that the system is ready for modern industrial IoT (IIoT) environments by providing a robust Ethernet interface that supports simultaneous connections for both monitoring and configuration. Its rugged design ensures long-term stability in harsh industrial settings, maintaining the high availability standards required for critical rotating machinery in power generation, oil and gas, and petrochemical sectors.
