      Information

      Overview Manuals Common Applications Product Precautions
      Bently Nevada 125800-02 is the isolated Keyphasor I/O module with internal terminations, designed primarily for magnetic-pickup inputs in a 3500/25 system. It can isolate parallel Keyphasor connections to multiple devices.
      • Isolated internal-termination execution
      • Designed primarily for magnetic pickups
      • Parallel Keyphasor system isolation
      • Speed-focused input with documented phase shift

      Use 125800-02 with the matched Enhanced Keyphasor main module and document every parallel destination. For a Proximitor input provide the required external supply, then verify isolation, threshold, speed indication and the additional phase shift before using phase data.

      Important Notice: Confirm quotation scope, physical marking, included accessories and installed-system compatibility before work.

      Magnetic-pickup speed sensing
      Accepts passive pickup pulses for shaft-speed timing above the published minimum speed.
      Parallel control-system reference
      Provides isolation where one Keyphasor signal is tied to multiple devices.
      Redundant timing architecture
      Supports documented primary and backup Keyphasor arrangements in paired modules.
      Isolated Proximitor reference
      Accepts a Proximitor signal when the required external transducer supply is provided.
      Read the applicable Bently Nevada documentation before work. Verify 125800-02 from the physical marking and the installed system record.
      1
      Confirm the complete 125800-02 isolated-module marking.
      2
      Pair it with the correct Enhanced Keyphasor front module and rear slot.
      3
      Keep the isolated input within +5 to -11 V.
      4
      Provide an external supply when a Proximitor transducer is used.
      5
      For passive magnetic pickups, confirm shaft speed exceeds 200 rpm.
      6
      Document every parallel destination and verify isolation before reconnection.
      7
      Account for the isolated I/O module's additional phase shift if phase is used.
      8
      Prove speed, timing, phase suitability and final rack diagnostics before release.

      FAQS

      • Why is 125800-02 called an isolated Keyphasor I/O module?
        It isolates a Keyphasor signal that is tied in parallel to multiple devices, such as a machinery-protection rack and a control system.
      • Which sensor type is 125800-02 primarily designed for?
        The manufacturer identifies it primarily for magnetic-pickup applications.
      • Can a Proximitor signal be connected to 125800-02?
        Yes, but an external power supply must be provided for the Proximitor application.
      • What voltage range is accepted by 125800-02?
        The isolated I/O input range is +5 V to -11 V.
      • What minimum speed applies to a passive pickup on 125800-02?
        A passive magnetic pickup requires shaft speed above 200 rpm, equivalent to 3.3 Hz.
      • Is 125800-02 preferred for precision phase work?
        Its primary intent is speed measurement; it can provide phase, but the isolated execution introduces more phase shift than the non-isolated version.
      • How should parallel destinations be checked when commissioning 125800-02?
        Record each destination, prove galvanic separation, verify signal amplitude at every device and confirm that no ground loop distorts the pulse.
      • What final evidence should be kept for 125800-02?
        Retain transducer type, external supply where used, input range, threshold, hysteresis, speed accuracy, phase-shift assessment and rack diagnostics.
