          PRODUCT DESCRIPTION

          126648-01 External Keyphasor I/O Module

          The Bently Nevada 126648-01 is the non-isolated external-termination I/O module for the 3500/25 Enhanced Keyphasor Module. It routes signals from proximity transducers or magnetic pickups to the front module, which uses the incoming pulses as a shaft timing reference.

          The 3500/25 accepts up to two transducer inputs. With the non-isolated I/O module, the documented input range is -21.0 to +0.8 V, the minimum input impedance is 21.8 kΩ, and the input frequency range is 0.017 Hz to 20 kHz. The rear module connects to a separate external termination block.

          SYSTEM INTEGRATION

          Integrate 126648-01 within Bently Nevada 3500/25

          Match the non-isolated external variant to the 3500/25 host and to the termination hardware already installed in the rack.
          Compare the sensor signal with the documented −21.0 to +0.8 V non-isolated input range. Check whether an isolated I/O option is required for the application.
          Record the configured signal and threshold settings for each Keyphasor channel. Use the applicable manufacturer guidance to verify event detection.

          Features:

          • Input isolation: Non-isolated
          • Termination type: External
          • Bently Nevada 3500/25
          Use 126648-01 only within the documented Bently Nevada 3500/25 arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 126648-01 within Bently Nevada 3500/25

          Identify both the 3500/25 front module and the rear I/O part number before an exchange. The 126648-02 is the isolated external-termination variant.
          Record the external block and cable routing separately from the rear module. Preserve the original assignment of the phase reference signals.
          Verify stable event detection and agreement with the expected timing reference before restoring downstream use.

          Features:

          • 126648-01 rear I/O identification
          • 3500/25 mating module and termination
          • Signal validation after exchange
          Use 126648-01 only within the documented Bently Nevada 3500/25 arrangement and applicable installation instructions.
