Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The CJ2M-CPU33 is an Omron CJ2M-series PLC CPU module, order code CJ2M-CPU33, with a 20K step program capacity and 64K words of data memory (DM: 32K words, EM: 32K words × 1 bank). It includes a built-in EtherNet/IP port and a USB programming port, plus an option slot for serial communication. ## Applications As a CJ2M-series PLC CPU, it serves as the central controller in machine automation, packaging lines, material handling, and process control applications, coordinating distributed I/O and field devices. The 20K step program capacity supports medium-complexity control logic, while the 64K words data memory (DM + EM) provides ample space for recipe storage and data logging. The built-in EtherNet/IP port enables high-speed plant-floor networking and programming without an add-on module, and the USB port offers a direct connection for local programming and diagnostics. The CPU supports up to 2,560 digital I/O points across a maximum of 40 expansion modules on 3 racks, suiting it to medium-scale machine control. ## Lifecycle The CJ2M-CPU33 is discontinued by Omron.","metaTitle":"Omron CJ2M-CPU33 PLC CPU, 20K Steps, 64K Words, EtherNet/IP, Discontinued","metaDescription":"Omron CJ2M-CPU33 PLC CPU: 20K step program, 64K words data memory, built-in EtherNet/IP, USB, DIN rail, IP20.
