Product Details
Bently Nevada 2300/25-00 is a 2300 Series vibration monitor with two seismic measurement channels and a speed input. It accepts vibration or position-related transducer signals, processes them for monitor variables and provides alarm and communication functions for a machinery monitoring installation.
The 2300/25 path in Bently Nevada 2300/25-00 includes a speed channel for synchronous measurements and relay contacts for alarm outputs. The unit exposes configuration and measured values through its Ethernet connection and the Modbus TCP/System 1 communication path.
The final 00 on Bently Nevada 2300/25-00 is the supplied approval selection. The monitor record therefore keeps the exact model, the 2300/25 hardware family and the approval field together when the installation is configured.

Product Functions
Bently Nevada 2300/25-00 combines vibration measurement, speed reference and alarm output in one monitor for two seismic channels.
Speed reference
The dedicated speed input supplies the timing reference needed for synchronous vibration measurements on Bently Nevada 2300/25-00.
Alarm output
Relay contacts change from the configured vibration and high-level conditions rather than acting as an unconfigured dry contact.
04
Communication and Connectivity
The external interface of Bently Nevada 2300/25-00 links the monitor to configuration software, System 1 and the plant network.
Ethernet port
The 10/100 Ethernet connection carries configuration and measured values from Bently Nevada 2300/25-00.
Modbus TCP
The monitor exposes its selected variables through the Modbus TCP path used by the connected host.
System 1 route
System 1 connectivity lets Bently Nevada 2300/25-00 provide the monitor data to the wider machinery-monitoring environment.

Frequently Asked Questions
Why can Bently Nevada 2300/25-00 show a normal vibration value but no PLC alarm?
Check the configured alarm variable, relay wiring and Ethernet/Modbus status for Bently Nevada 2300/25-00. The monitor value, relay contact and network register are separate paths, so a normal display does not prove that the PLC input is wired or mapped correctly.
What should be checked when the speed channel on Bently Nevada 2300/25-00 does not agree with the machine?
For Bently Nevada 2300/25-00, verify the speed pulse wiring, channel assignment and synchronous measurement setup before changing vibration limits. The speed input is used to relate the two seismic channels to machine running conditions.
How can a customer distinguish the two seismic channels on Bently Nevada 2300/25-00 during commissioning?
Label the two seismic inputs of Bently Nevada 2300/25-00 at the sensor and monitor terminals, then compare each channel value and alarm assignment separately. Swapping the channels can make a correct sensor appear to have the wrong machine location.
Why might Bently Nevada 2300/25-00 be unreachable over Ethernet?
Check the 10/100 Ethernet link, the Modbus TCP/System 1 address and the configured host connection for Bently Nevada 2300/25-00. A local display can remain active while the network path or register mapping is incorrect.
How should relay alarms from Bently Nevada 2300/25-00 be checked before connecting a shutdown circuit?
Use the front-panel status and the configured alarm thresholds on Bently Nevada 2300/25-00, then verify the relay contact state with the external circuit isolated. This separates monitor logic from a downstream shutdown-wiring issue.
Why should the complete Bently Nevada 2300/25-00 model remain on the order record?
Bently Nevada 2300/25-00 identifies the 2300/25 hardware and its final 00 approval selection. Keeping the complete string prevents the 2300/20 and other 2300 family records from being substituted during configuration or support.
