Bently Nevada 3500/62-03-00 Inputs and Outputs

Voltage & Current

Operating power: 24 VDC supplied from rack backplane; typical power consumption: 6.0 W

ICP sensor excitation: constant-current output 4 mA, excitation voltage 24 VDC

4-20 mA analog output: maximum allowable external load resistance 600 Ω

Inputs

independent transducer input channels for casing-mounted vibration measurement, compatible with ICP accelerometers and passive velocity pickups.

Built-in constant-current excitation output to power ICP-type accelerometers.

Keyphasor signal input transmitted over the rack backplane for order-tracking vibration analysis.

Bidirectional backplane communication bus input for configuration downloading and system time synchronization.

System power input: 24 VDC operating power delivered via 3500 rack backplane.

 Outputs

galvanically-isolated 4-20 mA analog output channels. Output values vary linearly with measured vibration magnitudes for connection to DCS and PLC automation systems.

Digital data output through rack backplane: transmits vibration measurements, spectral data, transient waveforms, alarm events and module diagnostic information to internal communication modules and upper-level software.

Front-panel LED status outputs including OK, Not-OK, Alert and Danger indicators for convenient local on-site status inspection.

Alarm status signals sent over the rack backplane to 3500 relay modules to trigger external alarm indication or equipment protection trip logic.

Supported Systems & Software

3500 Rack Configuration Software: used for module parameter setup, channel enabling, filter adjustment, alarm threshold definition and firmware management.

System 1 Condition-Monitoring Platform: receives spectrum, waveform and trend data to implement machinery health evaluation, fault diagnosis and historical-data recordingBaker Hugh

Compatible with the complete 3500-series rack hardware ecosystem, including 3500/20 gateway, 3500/22M TDI transient-data interface and relay modules.

Interfaces with third-party plant automation systems (DCS, PLC) via supporting communication modules, supporting Modbus-TCP, Modbus-RTU and proprietary Bently Nevada communication protocols.

Configuration software runs on mainstream Windows operating-system platforms.

Functions of Bently Nevada 3500/62-03-00 Condition Monitoring Module

Equipped with 4 independent monitoring channels, compatible with ICP accelerometers and passive velocity sensors, dedicated to continuous casing vibration measurement of rotating machinery.

Achieves high-precision real-time signal acquisition and computation, including overall vibration amplitude, bandpass filtered vibration values and frequency spectral data.

Supports user-configurable bandpass filtering functions, which can accurately extract characteristic vibration components such as 1X, 2X and subsynchronous frequency signals.

Each channel features independently programmable Alert and Danger alarm thresholds, with selectable latched and non-latched alarm modes to meet different protection logic requirements.

Integrates comprehensive sensor fault diagnosis functions, capable of detecting sensor open circuit, short circuit and power supply anomalies, and automatically activating Not-OK fault alarms.

Provides isolated 4-20 mA analog output for each channel, linearly corresponding to vibration measurement values, realizing stable data transmission to DCS and PLC systems.

Transmits real-time measurement data, alarm status and module diagnostic information to the 3500 rack backplane for upper-level communication modules and System 1 platform analysis.

Captures transient vibration waveforms and spectral data continuously, supporting equipment trend analysis, abnormal vibration tracing and mechanical fault identification.

Fully compatible with 3500 rack configuration software, enabling convenient parameter configuration, channel activation, filter calibration and alarm logic setting.

Cooperates with external Keyphasor signals to generate order-tracked vibration data, realizing professional rotating machinery vibration analysis.

Equipped with front-panel LED indicators to intuitively display channel OK status, fault status and alarm status for rapid on-site inspection.

Complies with API 670 industrial standards, providing reliable and stable condition monitoring and protection for critical industrial rotating equipment.
