8-Slot, Virtex-5 LX85 FPGA CompactRIO Chassis (Legacy)—The cRIO‑9116 is a rugged FPGA chassis that you can use to add C Series I/O modules to your distributed control or monitoring application. 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. This chassis requires a compatible CompactRIO Controller to communicate with the modules installed in the chassis.
