      Overview Manuals Common Applications Product Precautions
      Bently Nevada 3500/32M 125720-02 is the documented four-channel relay module component for the 32M product family.
      • Provides four independent SPDT relay outputs in one full-height module.
      • Combines Alert, Danger, Not-OK and Programmable Logic states with AND/OR voting.
      • Uses epoxy-sealed relays with arc suppression for controlled switching.
      • Supports documented standard-system and safety/hazardous-area output limits.

      Install 3500/32M 125720-02 only with the documented 32M front/rear module, termination hardware, transducers and approved 3500 rack configuration. Commissioning covers identity, signal path, scaling, alarms and controlled response.

      Important Notice: Confirm the complete 3500/32M 125720-02 identity, installed interfaces, approved configuration and final functional acceptance record before service release.

      Important Notice: The first document is an exact-model technical reference. The second is the unmodified official manufacturer family datasheet used for installation limits and technical evidence.

      Alarm annunciation
      Drive a documented annunciator or interface from independent rack alarm logic.
      Protection interlock
      Combine approved Alert, Danger and channel-status states in a programmed relay expression.
      Equipment permissive
      Use relay voting to provide an engineered machine permissive within the stated contact envelope.
      Shutdown interface
      Transfer a verified protection decision to the plant shutdown circuit through documented isolation.
      Read the applicable Bently Nevada installation instructions before work. Verify 3500/32M 125720-02, its installed system arrangement and configured interfaces before commissioning.
      1
      Verify whether the exact spare is a control module or an output module before replacement.
      2
      Confirm the installed system uses standard or safety/hazardous relay ratings before connecting the load.
      3
      De-energize the external relay circuit and verify isolation before removing either front or rear module.
      4
      Restore each output's normally energized or de-energized programming from the approved configuration.
      5
      Check AND/OR voting logic against the cause-and-effect record rather than copying neighboring channels.
      6
      Keep switching voltage, current and VA inside the published envelope, including inrush conditions.
      7
      Prove each relay using a controlled input state and observe both rack indication and external circuit response.
      8
      Record final relay state, logic expression, contact path and alarm/shutdown acceptance result.

      FAQS

      • Why is 3500/32M 125720-02 reserved for hazardous-area and functional-safety relay service?
        125720-02 is the documented output module variant for those systems, so its identity and restricted contact envelope must be preserved.
      • What reduced voltage boundary applies to circuits switched by 3500/32M 125720-02?
        For the safety/hazardous configuration, keep the switched circuit at or below 30 Vac/Vdc and 2 A.
      • How should normally energized logic be restored around 3500/32M 125720-02?
        Recover the approved relay logic and fail-state strategy from the safety or hazardous-area configuration; do not infer it from present contact state.
      • Which rack conditions may command the output paired with 3500/32M 125720-02?
        The 3500/32M logic can combine Alert, Danger, Not-OK and Programmable Logic states using AND/OR expressions.
      • What does the 250 Vrms suppressor specification imply for 3500/32M 125720-02?
        It identifies the installed arc-suppression component; external circuit design must still comply with the lower safety/hazardous contact rating.
      • How is the 5.8 W module load relevant when replacing 3500/32M 125720-02?
        Confirm the completed relay assembly and rack power budget remain consistent with the documented 5.8 W typical consumption.
      • What inspection should precede insertion of 3500/32M 125720-02?
        Inspect the rear connector, field wiring, channel labels and safety/hazardous circuit isolation before seating the output module.
      • Which acceptance evidence is needed for 3500/32M 125720-02 in a safety-related circuit?
        Retain the exact spare identity, programmed logic, de-energized test state, external circuit response and authorized proof-test result.
