CJ2M-CPU32 SYSMAC CJ2M CPU Unit 10K Steps EtherNet/IP | Omron

The Original New Omron CJ2M-CPU32 is a high-performance CPU unit for the SYSMAC CJ series programmable logic controller (PLC) platform, featuring a built‑in EtherNet/IP port for seamless network integration. With a program capacity of 10K steps, 32K words of data memory, and 32K words x 1 bank of extended memory (EM), this CPU is engineered for medium‑scale machine automation and OEM control systems. 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.
