Bently Nevada 2300/20 and 2300/25 Vibration Monitors Datasheet
The 2300 series vibration monitors are designed for continuous condition monitoring and protection of less‑critical machinery across industries such as oil & gas, power generation, water treatment, and mining. They accept two acceleration/velocity/proximity inputs, a dedicated speed channel, and provide real‑time measurements with alarm configuration.
Key features include Ethernet 10/100 Base‑T communication, configurable 4‑20 mA outputs (2300/20) or Trendmaster SPA interface (2300/25), three buffered transducer outputs, and extensive compliance certifications (FCC, ATEX, IECEx, RoHS). The monitors are panel‑mountable, support Modbus over Ethernet, and can store alarm data during network outages.

Bently Nevada Velomitor and Pepperl+Fuchs KFD2-VR4-EX1.26 Application Note
The note describes the hardware setup required to interface the Velomitor with the KFD2‑VR4‑EX1.26 isolator, including jumper settings, external power supply connection, and wiring polarity. It also warns that the 3500/42M monitor cannot supply enough current for the isolator, so a +24 VDC external supply must be used.
Software configuration steps are provided for the Rack Configuration software, covering channel pair selection, transducer type settings, and OK‑limit adjustments. The document lists conditions that trigger a NOT OK state on the monitor and points to additional resources on both manufacturers' websites.
