81725-XX Bently Nevada Output Module

Product  Description：

• Bently Nevada Output Modules are interface components within Bently Nevada's machinery protection systems, such as the 3500 and Orbit 60 series. These modules provide the means for the monitoring system to interact with external devices based on the analyzed condition of rotating machinery. They typically offer relay outputs, analog outputs, or digital outputs to trigger alarms, initiate shutdowns, or provide signals to other control systems.   

   

   

  Key Functions

  • Alarm Indication: Triggering external alarms (visual or audible) when machinery condition thresholds are exceeded.   
     
  • Machine Shutdown: Initiating safety shutdowns of machinery to prevent catastrophic failures.
  • Control System Interface: Providing signals (analog or digital) to plant-wide control systems (e.g., DCS, PLC) for integration of machinery health data.
  • Data Transmission: Outputting processed data or status signals for recording or further analysis.

  Product Parameters (Typical)

  • Output Types: Relay (Form A, Form C), Analog (4-20 mA, voltage), Digital (TTL, discrete).
  • Number of Channels: The number of independent output channels available (e.g., 4-channel, 16-channel).
  • Relay Contact Ratings: Maximum voltage and current the relay contacts can switch.
  • Analog Output Range: The range of the analog signal (e.g., 4-20 mA, +/-10 V).   
     
  • Digital Output Logic: Logic level and current sourcing/sinking capabilities.
  • Isolation: Electrical isolation between channels and from the backplane.
  • Power Requirements: Voltage and current drawn by the module.
  • Operating Temperature: The range of ambient temperatures the module can operate within.

  Product Advantages

  • Reliable Actuation: Provides dependable outputs for critical protection and control functions.
  • Flexible Configuration: Output functions (e.g., alarm voting logic, trip delays) are often software-configurable to suit specific application requirements.   
     
  • Seamless Integration: Designed to work seamlessly with Bently Nevada monitoring systems.
  • Enhanced Safety: Enables automated responses to machinery faults, improving plant safety.
  • Reduced Downtime: Facilitates early intervention and prevents major equipment failures, minimizing downtime.   
     

  Precautions

  • Electrostatic Discharge (ESD): Handle modules with appropriate ESD precautions to prevent damage.
  • Wiring: Ensure correct wiring according to the module's terminal diagrams and specifications. Incorrect wiring can lead to malfunction or damage.
  • Power Supply Compatibility: Verify that the power supply connected to the external devices is compatible with the output module's ratings.
  • Environmental Limits: Operate the module within its specified temperature and humidity ranges.
  • Configuration Accuracy: Ensure the output logic and parameters are correctly configured in the Bently Nevada monitoring system software. Incorrect configurations can lead to unwanted or failed actions.
  • Safety Interlocks: When using output modules for safety-critical functions (e.g., machine shutdown), ensure that proper safety interlocks and procedures are in place.

  Product Applications

  Bently Nevada Output Modules are essential in various industrial applications where machinery condition monitoring and protection are critical, including:

  • Oil & Gas: Protecting turbines, compressors, pumps, and other critical rotating equipment in refineries, pipelines, and offshore platforms.   
     
  • Power Generation: Monitoring and protecting turbines, generators, and boiler feed pumps in power plants.   
     
  • Petrochemical: Safeguarding critical machinery in chemical processing plants.
  • Manufacturing: Protecting large rotating equipment like motors, fans, and mixers in heavy industries.
  • Pulp & Paper: Monitoring and protecting rotating equipment in paper mills.   
     
  • Mining & Cement: Protecting critical machinery in harsh operating environments.

  Typical Applications

   

  • Triggering a visual alarm in the control room when a turbine's vibration level exceeds a predefined alert threshold.
  • Initiating an automatic shutdown of a critical compressor when a high vibration or bearing temperature danger threshold is reached.
  • Providing a 4-20 mA signal proportional to a machine's vibration amplitude to a plant's Distributed Control System (DCS) for continuous monitoring and trending.
  • Activating a solenoid valve to bypass a piece of equipment based on a specific machinery condition.
