      Overview Manuals Common Applications Product Precautions
      Bently Nevada 125720-01 is the four-channel relay output module used with a 3500/32M relay control module. It exposes four programmable SPDT contacts for machinery alarm and shutdown logic.
      • Provides four independent SPDT relay-output channels
      • Receives programmed alarm-drive logic from the 3500/32M control module
      • Supports normally energized or normally de-energized operation per relay
      • Switches external annunciation, trip and interlock circuits within documented contact ratings

      125720-01 installs with 3500 rack rear slot, 3500/32M relay control module, Alarm-drive logic configuration, Protected external trip or annunciation circuits in an engineered 3500/32M Relay System configuration.

      The commissioning workflow covers installed-hardware matching, controlled start-up and functional verification for this four-channel relay output module.

      Important Notice: Confirm the complete 125720-01 marking, installed-system configuration, field connections and controlled functional test before commissioning or replacement.

      Read the applicable Bently Nevada installation instructions before work. Verify 125720-01 and the installed 3500/32M Relay System configuration.
      1Confirm 125720-01 is assigned to the rear slot paired with the intended 3500/32M control module.
      2Isolate every AC and DC field source before touching the relay terminals.
      3Record common, normally open and normally closed conductors for all four SPDT channels.
      4Verify the normally energized or de-energized selection for each relay before power-up.
      5Keep switched voltage and current within the published standard-system ratings.
      6Use the restricted ratings when the rack is approved for hazardous-area or functional-safety service.
      7Recreate the documented Alarm Drive AND/OR logic in Rack Configuration Software.
      8Test Alert, Danger, Not-OK and selected PPL inputs without bypassing plant safeguards.

      Technical notes

      Technical notes

      Review each contact load and relay energization philosophy, isolate every external source at the terminals and prove the configured AND/OR voting logic before reconnecting shutdown circuits.

      FAQS

      • How should 125720-01 be isolated before field wiring is disturbed?
        Place the protected machine in its approved maintenance state, isolate rack and field energy applicable to Alarm-drive logic configuration, and prove the terminals safe before disconnection.
      • Which configuration should be restored after replacing 125720-01?
        Restore the approved 3500/32M Relay System slot, channel or interface configuration and verify that every connected circuit retains its original assignment.
      • How can 125720-01 be commissioned for machinery shutdown relay logic?
        Apply a controlled input or command, review the model-specific diagnostics and prove the expected measurement, indication and protection response before releasing the channel.
      • What technical value deserves special attention when checking 125720-01?
        Verify the published relay sealing value of Epoxy-sealed against the installed configuration and test record.
      • Can 125720-01 be exchanged with another 3500 I/O or monitor execution?
        Only when the complete part number, termination style, transducer or interface type and approved rack configuration match the installed duty; do not transfer settings from an adjacent model.
      • What evidence should be retained after 125720-01 returns to service?
        Retain the full 125720-01 identity, as-left connections, restored configuration, final diagnostics and the controlled functional-test result for alert and danger annunciation.
      • Which rack hardware must be matched before installing 125720-01?
        Match 125720-01 to the documented 3500 rack rear slot and 3500/32M relay control module; confirm the front/rear slot pairing and the complete physical marking before connection.
      • What as-found information should an engineer record before removing 125720-01?
        Record every channel or port assignment, connector identity, configured function, cable tag and diagnostic state associated with 125720-01.
