Issue Details

I am using an NI System on Module (SOM) inside a product. However, this product is going to be used in lots of different environments which change in temperature from 20°C to 60°C.
I am trying to figure out what the max ambient temperatures are if the SOM is running close to max power and uses different heat-sinks.

Solution

Creating an enclosure for a RIO is application and environment specific and there are many factors that effect the overall temperature of the RIO. Because of this, National Instruments is unable to supply comprehensive data for system integrators to design environment chambers or cooling systems.

However, we do recommend the following to get you started with your design:
  1. Run the code on the RIO and use the RIO's onboard temperature sensor to monitor the temperature. This will let you know to what degree you need to implement cooling.
  2. For optimal heat dissipation, we recommend you mount the SOM on a panel or plate. This could be inside a thermal chamber if required. For more information, see this article.
