New and Original Bently Nevada 3500/50M 286566-02 Tachometer Module in Stock

The Bently Nevada 3500/50M 286566-02 is a dual-channel tachometer module for the 3500 machinery protection system. It processes signals from proximity probes or magnetic pickups to measure shaft speed, rotor acceleration, and rotation direction. The module compares readings against user-programmable alarm setpoints and can supply conditioned Keyphasor® signals to the 3500 rack backplane, eliminating the need for a separate module. It features a peak hold function that stores maximum speed and reverse rotation data for post-event analysis.

    Model Number Description Key Differences
    3500/50-01-CN Replacement for discontinued 3500/50 variants Active production model; updated design for 3500 series 
    3500/50M 288062-02 Tachometer Module Similar 2-channel module; same functional specifications 
    3500/50-01-01-01 Original Tachometer Module (discontinued) Legacy model; direct predecessor to -CN replacement 
    3500/42 Proximitor/Seismic Monitor Vibration monitoring rather than speed; measures displacement/velocity
    3500/25 Enhanced Keyphasor Module Dedicated phase reference module; separate hardware if Keyphasor not integrated into tachometer 

    FAQ

    1: What sensors can the 3500/50M 286566-02 accept?

    A: The module accepts input from proximity probes (eddy-current, e.g., 3300 or 7200 series) or magnetic pickups to measure shaft speed, acceleration, and directio.

    2: Does this module provide Keyphasor signals?

    A: Yes. The 3500/50M can be configured to supply conditioned Keyphasor signals to the 3500 rack backplane for use by other monitoring modules, eliminating the need for a separate Keyphasor module in the rac.

    3: What is the peak hold feature?

    A: The peak hold function stores the highest recorded speed, highest reverse speed, or the number of reverse rotations experienced by the machine. These stored values can be reset via the monitoring system configuration interface.

    4: How is the module configured?

    A: The module is programmed using the 3500 Rack Configuration software. It is shipped unconfigured from the factory and must be configured after installation to perform specific monitoring functions (speed, acceleration, direction, etc.) .

    5: Can I hot-swap this module?

    A: Yes, the 3500/50M supports hot-swapping within the 3500 rack, allowing replacement without powering down the entire system.
