Modular DIN-rail PLC CPU with 20K steps, 64K-word memory, RS-232C/USB ports, and 2560-point expansion capacity.
CJ2M-CPU13 is an Omron CJ2M-series CPU unit for modular PLC systems. Manufacturer and distributor listings identify it as a DIN-rail programmable controller CPU with 20K-step program capacity, 64K words of memory, RS-232C and USB programming interfaces, and support for up to 3 expansion racks / 40 modules / 2560 I/O points. The Omron datasheet also shows the product family includes a one-port RS-232C option board, one RS-422A/485 option board, and a built-in 24 V-side expansion architecture typical of CJ2M CPU units.

Fits small to mid-size assembly or packaging cells that need a modular PLC with 20K steps, 64K words, and simple serial/USB commissioning.
Provides deterministic control for multi-station sequencing without needing a larger controller platform.
Well suited for retrofits where existing printers, scales, barcode readers, or drives still communicate over RS-232C or serial protocols.
Preserves serial connectivity while modernizing the control core and allowing expansion racks for added I/O.
Appropriate for distributed conveyor, indexing, and material-handling systems that need a compact CPU with room to grow to 2560 I/O points.
Enables scalable I/O growth and machine expansion without replacing the CPU platform.
