CJ2M-CPU35 SYSMAC CJ2M CPU Unit 60K Steps EtherNet/IP | Omron

The Original New Omron CJ2M-CPU35 is the highest-capacity CPU unit in the SYSMAC CJ2M series, featuring a built-in EtherNet/IP port and a program capacity of 60K steps, supported by 20K steps of function block memory. With 160K words of total data memory (32K words DM + 32K words × 4 banks EM) and 0.04 μs LD instruction execution time, this CPU is engineered for large-scale machine automation, complex OEM control systems, and data-intensive applications requiring extensive memory and high-speed processing. The integrated USB programming port simplifies connectivity, while the option board slot supports RS-232C or RS-485 serial communication modules for flexible field device integration. Up to 2,560 I/O points and three expansion racks allow scalable system expansion for packaging machinery, material handling, and general factory automation.

⚠️ Important Product Status Note:
