cRIO-9048

The NI cRIO-9048 is a rugged 8-slot CompactRIO embedded controller designed for deterministic industrial automation, synchronized distributed control, FPGA-based signal processing, and industrial edge computing applications. The controller combines an Intel Atom quad-core processor, a programmable Xilinx Kintex-7 FPGA, and TSN (Time-Sensitive Networking) capability into a compact industrial platform optimized for real-time control systems.

Unlike conventional PLC systems that rely mainly on software execution, the cRIO-9048 integrates FPGA hardware acceleration and deterministic real-time processing into a unified architecture. This allows engineers to implement ultra-low-latency control loops, synchronized acquisition systems, industrial protocol processing, and inline signal analysis directly at the hardware layer.

Typical applications include:

• Industrial automation
• Robotics and motion systems
• Distributed measurement systems
• Automotive HIL simulation
• Smart manufacturing
