Information
- Bently Nevada 2300/25-00 brings continuous machine measurements, alarm handling and the existing Trendmaster data path together for essential machinery with a small sensor-point count.
Plant interface: Trendmaster SPA and Ethernet Modbus
Protection outputs: Two programmable relays
Its SPA output supports the Trendmaster DSM/System 1 Classic data path, while Ethernet provides configuration and Modbus communication. The SPA frequency response is 10-3000 Hz within+/-5%; that interface limit is distinct from the wider configurable input measurement filters.
Two programmable relays and local contacts support alarm handling, bypass, configuration lockout and latched reset. Three BNC buffered outputs expose the two vibration signals and speed signal for diagnosis. The final 00 selects the no-approvals configuration; do not apply hazardous-area classifications from other variants.
2300/25-00 Official Technical Excerpt
The original technical excerpt for Bently Nevada 2300/25-00 covers SPA monitor functions, channel limits and interface arrangements. PDF · 9 pages.2300/25-00 Installation & Verification Guide
Apter Power installation and verification guide covering sensor assignment, SPA integration, alarm restoration and relay verification. PDF · 5 pages.
Application scope: Use the two vibration channels and speed channel for the assigned machine points. Protection setpoints and supported sensor types must match the machinery application.
Essential-machine protection
Continuously compare configured vibration measurements with alarm setpoints.Existing Trendmaster integration
Bring monitor signals into a compatible DSM SPA infrastructure.Synchronous machine diagnosis
Use the speed/Keyphasor input with configured synchronized measurements.Local maintenance access
Observe live status and buffered signals while applying controlled bypass/reset functions.
Record both vibration sensor types, sensitivities, scales and filters, together with the speed sensor and event-per-revolution configuration.
Place the monitored machine in its approved maintenance condition. Record relay logic, bypass and reset behavior before disconnecting any field circuit.
Verify 18-36 VDC supply and the configured sensor wiring. Keep the main vibration inputs and dedicated speed path identified separately.
Load the retained measurement groups, filters, setpoints and relay states. Confirm configuration-lockout and bypass contacts are in their intended test condition.
Confirm the receiving Trendmaster signal and actual relay circuit behavior. An on-screen alarm alone does not establish the external contact path.
Exercise the authorized reset, configuration-lock and bypass functions. Remove only the maintenance states that have been approved for release.

Technical notes
SPA verification: Compare the signal presented to the scan interface within its specified frequency and input-voltage envelope. Do not apply current-loop expectations to the SPA connection.
Contact thresholds: Use the defined low- and high-resistance contact states in an input test. Confirm the resulting monitor action rather than relying only on continuity.
FAQ View All FAQ
-
What does the final 00 select on 2300/25-00?It is the no-approvals option for the 2300/25 SPA-output monitor. Do not infer an explosive-atmosphere certification from the family name.
-
What DC source is required by 2300/25-00?The monitor requires 18-36 VDC with a maximum 7.5 W demand. Include connected sensor and installation conditions in the system design.
-
Is the SPA signal of 2300/25-00 equivalent to a 4-20 mA process loop?No. The SPA output uses high/low AC and DC gap signal paths for the Trendmaster interface rather than the current-loop output arrangement of 2300/20.
-
What frequency band is specified for the SPA output of 2300/25-00?SPA response is 10-3000 Hz within+/-5%. This is separate from the configurable channel measurement filters.
-
What input-signal ranges apply to the SPA interface of 2300/25-00?The SPA ranges are 8 Vpp high AC, 1.6 Vpp low AC and 0 to-20 VDC gap. The gap mode has a 1 Vpp maximum measurable AC signal.
-
How does 2300/25-00 detect a contact-input request?Contact inputs activate over 0-10 kilohms and deactivate from 150 kilohms to open circuit. Use the assigned lockout, bypass or reset input.
-
What conversion architecture is used by 2300/25-00?The input channels have independent 24-bit ADCs. Application response still depends on selected measurements, filters and configured alarm logic.
-
Can the relay circuits of 2300/25-00 be validated only from a displayed alarm?No. Check the programmed alarm, relay state and actual field circuit. The monitor does not provide output feedback determination for the relay contact path.
