      Overview Manuals Common Applications Product Precautions
      Bently Nevada 3500/20 125744-02 is a Rack Interface Module for the 3500 machinery-protection system. It manages rack communications, configuration access and system-level status exchange.
      • Provides the primary configuration and communication interface for a 3500 rack
      • Collects rack status and monitoring information for compatible host software
      • Supports front-panel local serial access and rear host-network connections
      • Coordinates rack address, keylock and system-contact functions

      3500/20 125744-02 installs with 3500 rack, 125768-01 or approved RIM I/O module, Rack Configuration Software, RS232 or RS422 host network in an engineered 3500 Machinery Protection System configuration.

      The commissioning workflow covers installed-hardware matching, controlled start-up and functional verification for this rack interface module.

      Important Notice: Confirm the complete 3500/20 125744-02 marking, installed-system configuration, field connections and controlled functional test before commissioning or replacement.

      FAQS

      • Which rear I/O module should be paired with 3500/20 125744-02?
        Use the rear I/O execution documented for the installed serial interface and rack topology; verify the complete I/O part number before insertion.
      • How is the rack address handled when replacing 3500/20 125744-02?
        Record the installed rack address before removal, restore the same unique address and verify host communication before reconnecting remote clients.
      • Which serial path is appropriate for local setup of 3500/20 125744-02?
        The front-panel RS232 ASCII interface is the local configuration path; use the documented baud selection and approved cable.
      • What must be recorded before removing 3500/20 125744-02?
        Record keylock state, rack address, host link type, communication rate, system-contact wiring and the current diagnostic condition.
      • How should host communication be tested after installing 3500/20 125744-02?
        Confirm CONFIG OK, establish communication from the assigned workstation and verify configuration access plus rack-data retrieval.
      • Can 3500/20 125744-02 be inserted in any 3500 rack slot?
        Use the Rack Interface Module position defined by the 3500 rack architecture and pair it with the corresponding rear I/O module.
      • What does an engineer verify if 3500/20 125744-02 shows a communication fault?
        Check rack address, interface selection, cable type and length, baud rate, rear I/O seating and host configuration before changing hardware.
      • What evidence should be retained after commissioning 3500/20 125744-02?
        Retain the complete part identity, restored rack configuration, host-communication test, system-contact results and final diagnostics.
