A Bently Nevada Analog Module, often referred to as a Recorder Output Module, generates a continuous analog signal (typically a current or voltage) that is directly proportional to a specific machine measurement. This output allows other control systems, data historians, or display devices to receive and interpret the processed vibration, position, temperature, or other machinery health data that the Bently Nevada monitoring system is collecting.

Functionality: The primary purpose of these modules is to provide an interface for the Bently Nevada system to external systems. They take a digitally processed measurement from a Bently Nevada monitor (e.g., a vibration amplitude, shaft position, or bearing temperature) and convert it into a standard industrial analog signal. This signal can then be used for trending, alarming in a distributed control system (DCS), or display on local panel meters.
Common Types/Examples:

3500/90 Series (e.g., 3500/92 Communications Gateway Module with analog output capability): While a gateway, it can facilitate analog outputs.
Orbit 60 Series Recorder Output Module (e.g., Orbit 60R/REC01): This is a dedicated analog output module within the newer Orbit 60 platform.

Key Features:

Proportional Output: The output signal (e.g., 4-20 mA) directly corresponds to the full-scale range of the measured parameter (e.g., 0-50 mm/s vibration).
Multiple Output Types: Typically supports industry-standard current (4-20 mA) and voltage (1-5 V, 0-10 V) outputs.
Configurability: Output ranges and scaling are often software-selectable to match specific interfacing equipment.
NAMUR NE43 Compliance: Many modules support extended output ranges (e.g., 3.8 mA to 20.5 mA) for fault indication, adhering to the NAMUR NE43 standard.
Channel OK LEDs: Visual indicators for module and channel status.
Clamping Function: User-configurable output levels to indicate an invalid measurement status or fault within the module or wiring.

Product Parameters

Specific parameters depend on the module series and model, but common ones include:

Output Types: 4-20 mA, 1-5 VDC, 0-10 VDC.
Load Resistance (for Current Output): Typically 0-600 Ohm.
Signal Output Error: Often 1% or less, ensuring high accuracy.
Update Rate/Signal Delay: Default update rates can be as fast as 1 ms, with maximum signal delays around 10 ms for quick response.
Number of Channels: Varies, but 8-channel modules are common.
Power Consumption: Typical and maximum power draw (e.g., 6 Watts typical, 11 Watts maximum for Orbit 60 REC01).
Environmental Limits: Operating temperature range (e.g., -30°C to +70°C for some modules in specific chassis), humidity (non-condensing).
Dimensions and Weight: Specific to the module and system rack (e.g., full-height, single-slot modules).

Product Advantages

Seamless Integration: Provides a standard, reliable interface for Bently Nevada's specialized machinery data to be consumed by plant-wide control systems (DCS, PLC, SCADA) or data historians.
Enhanced Monitoring: Enables operators to view critical machinery health parameters on their primary control screens alongside process data, facilitating holistic monitoring.
Improved Decision Making: By providing analog outputs, the system allows for more comprehensive data trending and analysis, supporting proactive maintenance decisions.
Robustness: Designed for continuous operation in demanding industrial environments, ensuring consistent data availability.
Flexibility: Supports multiple analog output types and configurable ranges to suit various external systems.
Compliance: Adherence to industry standards like NAMUR NE43 ensures reliable fault indication and interoperability.

Important Considerations

Scaling and Range: Proper scaling of the analog output signal is crucial to ensure accurate representation of the Bently Nevada measurement in the receiving system. Mismatching ranges can lead to incorrect interpretations.
Load Resistance: For current outputs (e.g., 4-20 mA), ensure the load resistance of the receiving device falls within the module's specified limits to avoid signal degradation or damage.
Wiring Practices: Use shielded twisted-pair cables for analog signals to minimize electrical noise interference, especially over long distances. Follow proper grounding practices.
Receiving System Compatibility: Confirm that the DCS, PLC, or SCADA system can correctly interpret the specific analog signal type (current/voltage) and range provided by the Bently Nevada module.
Purpose: These modules typically provide data for monitoring, trending, and alarming, but are generally not intended for direct machine control or critical safety interlocks due to the potential for single point of failure and response time considerations. Always verify Bently Nevada's recommendations for safety-critical applications.
System Architecture: Understand how the analog module fits into the overall Bently Nevada system (e.g., 3500 rack, Orbit 60 chassis) and its dependency on other modules like monitors and communication gateways.
