Description

The BENTLY NEVADA 128710-01 is to terminate recorder output signals from compatible 3500 Series monitoring modules. Instead of connecting field wiring directly to the monitor I/O module, recorder output signals are routed through the external termination block, simplifying installation and maintenance while reducing wiring complexity.

The BENTLY NEVADA 128710-01 utilizes terminal strip connectors, making it suitable for installations where permanent field wiring is preferred. The terminal strip provides secure screw-type electrical connections and is commonly selected in industrial environments where vibration resistance and serviceability are important. The equivalent Euro-style connector version is 128702-01.

The Bently Nevada 3500/70M Recip Impulse Velocity Monitoris a 4-channel device used as part of the reciprocatingcompressor solutions package to monitor compressorcrankcase and crosshead vibration. The monitor acceptsinput from seismic transducers, conditions the signal toderive vibration measurements, and compares theconditioned signals with user-programmable alarms.

Technical notes

The BENTLY NEVADA 128710-01 is installed between the monitor I/O module and field recorder wiring using the appropriate 3500 external termination cables. This arrangement separates field wiring from the monitor electronics, improving accessibility during commissioning, maintenance, and module replacement while maintaining reliable recorder signal transmission.

FAQs

  • Does this termination block provide active surge protection?

    +
    No. This unit is a passive interconnect device and does not include active surge suppression components. External protection must be added separately if required by your environment
  • What system is the 128710-01 compatible with?

    +
    It is designed for use alongside the Bently Nevada 3500 Series monitoring systems and specific I/O module configurations requiring external recorder terminations.
  • Does it require a specialized cable to link to the rack?

    +
    Yes. It connects using designated multi-conductor transducer signal to external termination block cables (such as the 3500 series field wiring and signal cables).
  • What are the wiring rules?

    +
    All wire transitions require professional-grade insulated ferrules to secure contact, and orientation must permit proper heat dissipation.
