Product Description

The 3500/22M (146031-02) is a high-performance Transient Data Interface (TDI) module optimized for long-distance data transmission via fiber-optic connectivity. Serving as the primary communication hub for the Bently Nevada 3500 monitoring rack, this module integrates the core functions of a Rack Interface Module (RIM) with the high-speed processing power required for transient and seismic data collection.

Equipped with a 100Base-FX Ethernet interface, the 146031-02 is specifically designed for industrial environments where electrical interference or physical distance (up to 2000 meters) makes standard copper Ethernet impractical. It facilitates the seamless flow of static and dynamic waveform data to System 1 Condition Monitoring software, providing engineers with the high-resolution data necessary for machinery diagnostics and predictive maintenance.

Key Functional Features

• Immunity to EMI: The fiber-optic I/O provides total electrical isolation, preventing ground loops and electromagnetic interference in large plant networks.

• Transient Capture: Continuously monitors and captures waveform data during machine start-up, coast-down, and alarm events.

• M-Series Compatibility: Optimized for use with M-series monitors (e.g., 3500/42M) to handle high-density data throughput.

• Internal Diagnostics: Constant self-checking of the 3500 rack health with a dedicated OK relay for system-wide integrity signaling.
