The Omron CJ2H-CPU67 is a rack-mountable PLC CPU with 512K words of program memory, capable of driving up to 40 modules across three racks. It communicates via RS-232C and USB, mounts on DIN rail, and includes battery backup for data retention. Operating from 0 to 55°C, it suits standard industrial cabinets—including mill environments—though the temperature range is typical for industrial controllers, not extreme heat.
The CJ2M-CPU14 is the nearest functional sibling. It shares the same rack architecture, software, and communications, but has 160K words memory instead of 512K words. It is a viable second-source if your application fits within 160K words.
