The GE PACSystems RX3i and RX7i represent the modern era of programmable automation controllers (PAC), bridging the gap between traditional PLCs and high-level computing. This category features high-performance CPUs, Gigabit Ethernet backplanes, and high-density I/O designed for modern, data-intensive industrial environments. The RX3i offers a compact, high-speed solution, while the RX7i provides the VME64-based processing needed for high-end integrated control. These components are essential for facilities requiring high availability, cyber-secure communications, and seamless integration with Industrial Internet (IIoT) platforms.
