temperature of the components should not exceed the recommended maximum case
temperature.
Managing Power and Feature Utilization
An sbRIO-96xx that heavily utilizes all of its performance and features consumes and
dissipates substantially more power than an idle device.
Consider the following options for reducing the die junction temperature.
• Design for additional thermal cooling that can appropriately dissipate power
• Reduce device feature utilization
Note Your final validation must consider software and hardware utilization that is
representative of the final deployment conditions.
Note Refer to the device specificaions on ni.com/manuals for specifications that
approximate the maximum power requirement for each input rail on the sbRIO-96xx
with worst-case silicon manufacturing process and maximum junction temperatures.
For a more accurate estimate of the power consumption for a specific application, NI
recommends that you directly measure the power the sbRIO-96xx consumes when
running your application in an environment that is representative of the intended use
case.
Mounting Recommendations for Maximizing Thermal
Performance
Thermal performance of the sbRIO-96xx can be maximized by implementing the following
recommendations.
• Directly mount a thermal solution such as the Thermal Kit for CompactRIO Single Board
Controller with NI-DAQmx (787331-01) to a thermally conductive surface such as a
metal enclosure wall or plate. An interface material such as thermal grease should be used
to maximize the heat transfer from the heat spreader to the enclosure or plate.
If design limitations prevent this solution, you can alternatively attach a heat sink or other
thermal solution. This solution takes advantage of natural convection or forced cooling
provided by a fan.
• Mount the sbRIO-96xx vertically with respect to gravity to take advantage of natural
convection cooling.
• Mount the sbRIO-96xx below and away from other heat-dissipating components.
Note Placing the sbRIO-96xx within a system or enclosure will also influence
thermal performance.
