  • Provides Essential Machine Information
The Bently Nevada™ 3500/50M Tachometer Module is a 2-channel module that accepts input from proximity probes ormagnetic pickups to determine shaft rotative speed, rotoracceleration, or rotor direction. The module compares thesemeasurements against user-programmable alarm setpointsand generates alarms when the setpoints are violated.

The 3500/50M Tachometer Module can be configured tosupply conditioned Keyphasor signals to the backplane of the3500 rack for use by other monitors. Therefore, you don't needa separate Keyphasor module in the rack.

The 3500/50M Tachometer Module has a peak hold featurethat stores the highest speed, the highest reverse speed, orthe number of reverse rotations that the machine hasreached. You can reset the peak values.

The 3500/50M 288062-02 286566-02 Bently Nevada Tachometer Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 3500/50M accepts up to two independent transducer signals with an input range of +10.0 V to –24.0 V and input impedance options of 20 kΩ (standard), 40 kΩ (TMR), or 7.15 kΩ (internal barrier) to suit diverse installation requirements. It supports an exceptionally wide frequency spectrum: a minimum input frequency of 0.0167 Hz (1 RPM for 1 event per revolution) for proximity probes, and up to a maximum of 20 kHz, corresponding to a full-scale range of 99,999 RPM. Signal conditioning is highly flexible, supporting 1 to 255 events per revolution for Rotor Acceleration and Zero Speed channel types, and 0.0039 to 255 events per revolution for all other configurations. Transducer conditioning options include Auto Threshold (for inputs above 0.0167 Hz with a 1 V peak-to-peak minimum trigger amplitude) and Manual Threshold (user-selectable from +9.5 Vdc to –23.5 Vdc with 500 mV minimum amplitude), complemented by adjustable hysteresis from 0.2 to 2.5 volts to ensure reliable edge detection in noisy industrial environments

Rack Position: The 3500/50M uses one full-height rear slot.
External Termination: The 288062-02 ETB (External Termination Block) must be ordered separately and installed at the rear of the rack to facilitate sensor connections.
Wiring: Connect proximity probes or magnetic pickups to the Euro-style connectors on the 288062-02 block. The module accepts 1-2 transducer signals (+10.0 V to -24.0 V range).
Software/Firmware: Ensure 3500/22M module firmware is version 1.70 or later, and 3500/01 software is version 4.20 or later.

FAQs

  • What is the 3500/50M ?

    +
    The Bently Nevada 3500/50M Tachometer Module is a 4-channel module designed to monitor shaft speed, rotor acceleration, or reverse rotation on rotating machinery. It compares input signals against user-programmable setpoints to trigger alarms.
  • What sensors are compatible with the 3500/50M?

    +
    The module accepts input from 1 to 2 proximity transducers (proximitors) or magnetic pickups
  • Can the 3500/50M be used for overspeed protection?

    +
    No. The 3500/50M is not designed to be used independently for overspeed protection or speed control as it does not provide the necessary protective redundancy.
  • What are the different operational modes available?

    +
    The 3500/50M can be configured for four primary purposes: Speed Monitoring (with setpoint/speed band alarming), Zero Speed Notification, Rotor Acceleration Alarming, or Reverse Rotation Notification.
