NI unveiled a rugged 4-slot “CompactDAQ” system for data acquisition and control (DAQ), with real-time Linux, an Atom E3825, and optional sensor modules. Usually, when you have a choice of Windows or Linux, the Windows version costs more. In the case of the National Instruments (NI) CompactDAQ cDAQ-9134 Controller, however, it’s the Linux version that costs $500 more, at $4,999. That’s because it’s a special real-time Linux variant called NI Linux Real-Time, also available on NI’s CompactRIO cRIO-9068 controller and sbRIO-9651 computer-on-module, both of which are based on the Xilinx Zynq-7020 system-on-chip. The cDAQ-9134 instead runs on a dual-core, 1.33GHz Intel Atom E3825 SoC.
