      Overview Manuals Common Applications Product Precautions
      Bently Nevada 3500/25-SIL2-02-01-01 is the documented enhanced keyphasor module / four-channel sil2 ordering configuration for the 25 product family.
      • Accepts proximity-probe or magnetic-pickup phase reference inputs.
      • Processes four channels through two half-height two-channel cards.
      • Supports automatic or manual trigger thresholds and keyed event outputs.
      • Provides buffered phase signals for speed and vector measurements in the rack.

      Install 3500/25-SIL2-02-01-01 as the documented two-card, four-channel Keyphasor arrangement with its internal-termination I/O modules. Commissioning covers input waveform, trigger level, polarity, phase stability and speed indication.

      Important Notice: Confirm the complete 3500/25-SIL2-02-01-01 identity, installed interfaces, approved configuration and final functional acceptance record before service release.

      Important Notice: The first document presents exact-model technical data and engineering questions. The second provides a separate model-specific installation, configuration and acceptance workflow.

      Four-channel phase reference
      Provide independent keyed phase inputs for machines needing multiple shaft-reference channels.
      Speed-related measurements
      Supply phase timing used by compatible 3500 monitors for speed and vector calculations.
      Proximity-probe triggering
      Use a keyed shaft surface with the documented proximity-probe input envelope.
      Magnetic-pickup triggering
      Use compatible passive pickup signals when the minimum amplitude and speed conditions are met.
      Read the applicable Bently Nevada installation instructions before work. Verify 3500/25-SIL2-02-01-01, its installed system arrangement and configured interfaces before commissioning.
      1
      Confirm both half-height cards and both internal-termination I/O assemblies match the complete ordering configuration.
      2
      Match each channel to its documented proximity probe or magnetic pickup before energizing the rack.
      3
      Set automatic or manual trigger thresholds from an observed waveform, not from an assumed keyway amplitude.
      4
      Keep the non-isolated input within +0.8 to -21 V and preserve the rack grounding plan.
      5
      Verify keyed-event polarity and hysteresis before using phase in protection or diagnostic measurements.
      6
      Check the configured input frequency and the reported speed over a controlled run-up.
      7
      Protect the rear internal-termination wiring and confirm the correct half-height slot assignment.
      8
      Record final trigger level, phase stability, speed indication and channel OK state before release.

      FAQS

      • How do the two half-height cards in 3500/25-SIL2-02-01-01 provide four Keyphasor channels?
        The 02 monitor option specifies two two-channel half-height Enhanced Keyphasor cards, so the rack arrangement provides four processed phase-reference inputs.
      • Which transducer signal types can 3500/25-SIL2-02-01-01 accept at its four inputs?
        The datasheet permits proximity-probe signals and magnetic-pickup signals; the installed channel configuration and signal amplitude must match the selected type.
      • What input-frequency envelope should be checked for 3500/25-SIL2-02-01-01 during commissioning?
        The specified input range is 1 to 1,200,000 cpm, while the processed output speed range is 1 to 99,999 cpm.
      • When may 3500/25-SIL2-02-01-01 use automatic trigger threshold selection?
        Automatic threshold operation requires at least 2 V peak-to-peak input and at least 120 rpm; otherwise use a verified manual threshold.
      • What manual trigger limits apply when configuring 3500/25-SIL2-02-01-01?
        The published manual threshold range is 0 to -20 Vdc with a 0.5 V peak-to-peak minimum input signal.
      • How should trigger hysteresis be verified for 3500/25-SIL2-02-01-01?
        Use the configurable 0.2 to 2.5 V hysteresis range and verify stable keyed events without chatter over the operating waveform.
      • What rear termination arrangement belongs with 3500/25-SIL2-02-01-01?
        The 01 I/O option is the internal-termination module; verify both rear I/O assemblies and the corresponding half-height front-card positions.
      • Which release checks establish a usable phase reference from 3500/25-SIL2-02-01-01?
        Confirm channel OK state, stable keyed-event polarity, consistent phase, correct speed indication and repeatable triggering through a controlled run-up.
