Omron CJ2M-CPU31 Modular PLC – CPU Unit

The Omron CJ2M-CPU31 is a modular PLC CPU unit for mid-size systems, offering fast processing and Ethernet connectivity for advanced automation applications. Part of the Omron CJ series, this high-performance programmable logic controller allows expandable I/O racks and special function modules including analog I/O, temperature control, and motion control modules. The CJ2M-CPU31 features ultra-fast processing speeds (20 ns per instruction), extensive I/O capacity (up to 960 I/O points), and flexible communication options including Ethernet, serial ports (RS-232C/RS-422A/RS-485), and USB for seamless integration into industrial control systems. With 20K steps of program capacity and 128K words of data memory, this modular PLC is designed for complex control tasks requiring high-speed processing and extensive I/O handling. Commonly used in factory automation where more complex control and networking (EtherNet/IP) are required, the CJ2M-CPU31 supports advanced programming with CX-Programmer and Sysmac Studio software. Typical applications include manufacturing production lines, process control systems, material handling systems, and distributed automation networks requiring scalable I/O and advanced communication capabilities. Operating in temperatures from 0 to 55°C with 24V DC power supply, this modular PLC delivers exceptional performance for mid-range automation applications. For simpler automation needs, consider the Omron CP1E series micro PLCs, which offer cost-effective solutions for basic control tasks.
