4-Slot, Spartan-6 LX45 FPGA, Ethernet CompactRIO Chassis —The NI-9146 is a rugged Ethernet chassis that you can use to add C Series I/O modules to any standard Ethernet network. You can program the chassis using scan-mode for fast expansion of your real-time system or using the onboard FPGA for inline processing and high-speed I/O and control. The NI-9146 enables you to add high-performance I/O to your PC-based application or expand your CompactRIO, PXI, or industrial controller application.
