The RX7i PACSystem served as a high‑end successor to the 90‑70, providing Celeron/Pentium‑based CPUs with dual Ethernet and multiple serial ports. However, GE sunset the product in 2017, and it’s now only available as surplus or refurbished stock. If you already run RX7i controllers, you’ll want to source spares and plan a migration; if you’re considering new projects, skip this legacy platform and choose current PAC systems that offer long‑term support and cybersecurity enhancements.
