I. Basic Information

Model: 72358-51 (Part Number) = 3500/22M (Commercial Model)

Series: Bently Nevada 3500 Condition Monitoring System

Form: Semi-high card, occupying one semi-high slot in the 3500 frame

Function Positioning: Transient Data Interface (TDI), combining communication + data acquisition

II. Core Functions

Full-network data collection

Collecting steady-state + transient data from all M-series monitoring cards (3500/40M, 42M, 44M, etc.) within the frame

Supporting multi-parameter unified collection (vibration, displacement, temperature, phase alignment, etc.)

High-speed upload to the upper system

Sending waveforms, spectra, trend data to System 1, TDXnet, DCS/SCADA

Replacing the old system "3500/20 + communication processor", simplifying the architecture

Configuration and diagnosis

Providing Ethernet interface for local / remote configuration, calibration, and fault diagnosis

TMR redundancy support

In the three-redundancy (TMR) framework, automatic data comparison and fault switching to improve reliability

III. Technical Parameters (3500/22M)

Power Supply: Powered by the backplane of 3500 frame (+5V/+12V)

Power Consumption: Typical 7.7W, extended function 10.5W

Communication Interface:

Ethernet: 10/100Base-TX (standard, RJ45)

Optional: Fiber optic interface (more anti-interference)

Data Capability:

Steady-state: Full-channel real-time trend

Transient: High-speed waveforms, spectra, phase alignment (satisfying fault diagnosis)

Environment:

Operating temperature: -10℃ ~ +60℃

Storage temperature: -40℃ ~ +85℃

Size (H×W×D): Approximately 125 × 85 × 150 mm

Weight: Approximately 0.5 kg

IV. Model Suffix Explanation (72358-XX)

72358-51: Standard 3500/22M, most commonly used, with Ethernet

72358-52/53: Different firmware / regional versions or with fiber optic

72358-54: Extended function version (such as more protocols)

V. Typical Applications

Large steam turbine generators, gas turbines, compressors, fans, pumps, etc. of key rotating machinery

Online monitoring and fault diagnosis of key equipment in power plants, refineries, chemical plants, metallurgy, etc.

Standard configuration: 1 piece 3500/22M (72358-51) + multiple M-series monitoring cards

VI. Differences from 7200 Series Cards (you previously asked about 72471/72489)

72358-51 (3500/22M): 3500 system (new), communication / data interface card, semi-high

72471-B/BC, 72489-XX: 7200 system (old), monitoring card (shaft displacement / expansion difference), full height

VII. Common Combinations

3500/22M + 3500/40M (vibration)

3500/22M + 3500/42M (shaft displacement)

3500/22M + 3500/44M (temperature)
