GE PACSystems RX3i and RX7i represent the modern standard for Programmable Automation Controllers (PACs), built on a high-speed PCI Express backplane. The architecture enables high-performance logic, motion control, and high-speed processing through advanced CPUs like the IC695 series. Key technical characteristics include hardware-based security, hot-swap capabilities, and support for high-speed VersaMax I/O and PROFINET networks. Functionally, the RX3i is optimized for scalable machinery control, while the RX7i is designed for larger, complex DCS-style applications in the power and process industries. These controllers provide a seamless migration path for Series 90-30/90-70 users, ensuring high-speed data throughput and deterministic control for critical infrastructure and advanced manufacturing systems.
