• Configurable Parameters: Allows users to configure input ranges, filtering, and other parameters to match specific application needs.
• Diagnostic Capabilities: Some modules may include built-in diagnostics for sensor and module health monitoring.   
   

Precautions

• Wiring: Ensure proper wiring according to the module's terminal diagrams and specifications to avoid damage and signal errors. Use shielded cables where necessary to minimize noise.
• Sensor Compatibility: Verify that the sensor's output range and type are compatible with the analog input module's specifications.
• Power Supply: Ensure the Bently Nevada system backplane provides the correct power to the module.
• Electrostatic Discharge (ESD): Handle the module with appropriate ESD precautions during installation and maintenance.
• Environmental Conditions: Operate the module within its specified temperature and humidity ranges. Avoid exposure to excessive vibration, dust, and corrosive substances.
• Configuration: Configure the module parameters correctly within the Bently Nevada system software to ensure accurate data acquisition and processing.
• Calibration: Regularly calibrate the connected sensors and verify the module's accuracy as part of a comprehensive maintenance program.

Product Applications

Bently Nevada Analog Input Modules are used in a wide variety of industrial applications for monitoring critical machinery, including:

• Vibration Monitoring: Interfacing with accelerometers, velocity transducers, and displacement probes (via integrators).
• Temperature Monitoring: Connecting to Resistance Temperature Detectors (RTDs) and Thermocouples (TCs).
• Process Variable Monitoring: Acquiring signals from pressure transmitters, flow meters, level transmitters, and other process sensors.
• Speed Monitoring (Indirect): Receiving analog signals proportional to speed from certain speed sensors.
• General-Purpose Data Acquisition: Collecting various analog signals for comprehensive machine health analysis.

Typical Applications

• Monitoring bearing temperatures and vibration levels on large rotating equipment like turbines, compressors, and generators.
• Acquiring process data (e.g., pressure, flow) alongside vibration data for a holistic view of machine health.
• Interfacing with specialized sensors for specific machine condition parameters.
• Integrating data from third-party analog sensors into the Bently Nevada monitoring system.
