NI cRIO-9004 CompactRIO Real-Time Controller

The NI cRIO-9004 is a real-time embedded controller purpose-built for industrial automation, data acquisition, and control applications demanding deterministic execution and harsh-environment reliability. Centered on a 400 MHz PowerPC processor with 64 MB DRAM and 128 MB nonvolatile storage, it runs NI Real-Time Linux and delivers predictable timing for complex algorithms and large-scale data processing. The controller integrates directly into CompactRIO chassis, leveraging C Series module slots for flexible I/O expansion and processing acceleration.
