What is CompactRIO?
CompactRIO is a modular, compact, robust and open measurement system from NI, consisting of a real-time computer and a chassis for holding function modules, the so-called cRIO modules. Depending on the model, the chassis can accommodate 4 or 8 cRIO modules and has an FPGA (Field Programmable Gate Array). Further information on CompactRIO can be found on the NI website.
In addition to CompactRIO, there is also the NI CompactDAQ platform. This platform can only be used to a limited extent and only with specific S.E.A. modules.
What does S.E.A. offer for CompactRIO?
We offer so-called Third-Party cRIO modules. These provide various technologies and thus help to extend the platform with a variety of capabilities.
In addition to the already existing modules, we can develop modules on customer request.
cRIO modules with technologies such as mobile radio (4G), geo-positioning (GNSS), interfaces and busses or networking.
Accessories: mobile radio/GNSS antennas, mounting devices, cables

We have 48 S.E.A. 4G modules that we use to transmit real-time data from portable weather stations that are deployed into severe thunderstorms and hurricanes for research and informative purposes. In particular, the hurricane application benefits both the public and private sectors as in many cases our weather observations are among the only observations available in the most impacted areas of hurricane landfalls. We are very satisfied with the 4G/GPS Communications modules we have received. They have been very reliable, work great and the support has been fantastic as well.
We use SEA 9811 ARINC 429 modules in two different products for testing fuel systems of aircrafts. Each product utilizes a NI CompactRIO platform, which in turn, hosts SEA 9811 modules. One platform uses 3 SEA 9811 modules, the other one is equipped with 1 SEA 9811 module.
SEA 9811 ARINC 429 modules have proven themselves well in our application and the support has always been helpful.
