    Key Specification

    Item Specifications / Features
    Primary Function Main communication interface for the 3500 rack; supports proprietary protocol for configuration and data retrieval .
    System Platform Bently Nevada 3500 Series Rack; must be installed in Slot 1, immediately adjacent to the power supply .
    Communication Interface Front-panel RS232 serial port (38.4 k baud) for local configuration and data collection .
    Power Consumption 4.75 Watts (typical) .
    Module Type Standard full-height RIM (other variants, such as 135031-01, may include an integrated modem) .
    Operating Temperature -30°C to +65°C (standard) .
    Status Indication Front-panel LEDs for OK, TX/RX (communication), Trip Multiply, and Config OK .
    Key Switch Front-panel key-lock switch to toggle between RUN and PROGRAM modes, locking out configuration changes in RUN mode .
    OK Relay One OK relay output to indicate overall rack health (rated at 5A @ 24Vdc/120Vac) .

    Core Features & Advantages

    • Central Communication Hub: The module's standout feature is its role as the primary gateway for the 3500 rack. It is the only module through which configuration software can access the rack to set up monitors and retrieve non-critical machinery information.

    • Safe and Reliable Operation: A critical design aspect is that the RIM is independent of the critical machinery safety trip path. This ensures that maintenance or servicing of the RIM does not affect the normal protective operations of the monitoring system.

    • Hardware Security and Configuration Control: The front panel features a physical key-lock switch to prevent unauthorized changes to the rack's configuration. Switching to "PROGRAM" mode allows configuration changes, while "RUN" mode locks the configuration to ensure operational integrity.

    • User-Friendly Maintenance: It features a front-panel rack reset pushbutton for clearing latched alarms and supports hot-swappable replacement without powering down the rack, enabling online maintenance.

    Typical Applications

    The 3500/20 RIM is essential for communication and control in critical machinery monitoring systems, such as:

    • Vibration Monitoring Systems: Acts as the interface for configuring monitors and retrieving vibration data in power generation and oil & gas.

    • Protection Systems: Provides system-level control functions like trip multiply and status monitoring for the entire protection rack.

    • Data Acquisition Systems: Serves as the data gateway to connect the 3500 system with plant-wide DCS, PLC, or SCADA systems.
