      Overview Manuals Common Applications Product Precautions
      Bently Nevada 125768-01 is the rear I/O module for a 3500/20 Rack Interface Module, providing selectable RS232 or RS422 host communication. It supports rack configuration and machinery-information retrieval through the Bently Nevada proprietary protocol.
      • Selectable RS232 or RS422 host interface
      • 38.4 kbaud maximum serial communication
      • Up to 1200 m RS422 cable length
      • Full-height rear-slot installation

      Pair 125768-01 with the documented 3500/20 RIM and set its RS232/RS422 selector to match the installed physical layer. Verify rack address, cable length, shield and host communication before enabling remote configuration.

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

      FAQS

      • Which front module must 125768-01 accompany?
        It is the RS232/RS422 I/O module for the 3500/20 Rack Interface Module; verify the documented front/rear pairing.
      • How is RS232 or RS422 selected on 125768-01?
        Use the I/O module's physical RS232/RS422 selector and record its as-found position before disturbance.
      • What is the maximum serial rate for 125768-01?
        The official 3500/20 datasheet specifies 38.4 kbaud maximum with automatic baud capability.
      • What distance limit governs an RS232 link from 125768-01?
        The manufacturer limit is 30 metres or 100 feet.
      • How far may the RS422 interface on 125768-01 run?
        The published RS422 cable-length limit is 1200 metres or 4000 feet.
      • Does 125768-01 use a general-purpose Modbus protocol?
        No. The official record identifies the communication protocol as Bently Nevada proprietary.
      • What contact current should be expected at the system contacts on 125768-01?
        Trip Multiply, Alarm Inhibit and Rack Reset use dry contacts to common with less than 1 mA dc maximum current.
      • What should a host-link acceptance test for 125768-01 prove?
        Confirm selector position, rack address, serial rate, configuration access, machinery-data retrieval and a fault-free final rack state.
