Specification

The OMRON CJ2H-CPU64-EIP, CJ2H-CPU65-EIP, and CJ2H-CPU66-EIP are flagship CPU Units of the CJ-Series, designed for demanding industrial automation environments. These controllers integrate a powerful EtherNet/IP port for seamless network connectivity, enabling tag data links and high-speed communication. With a compact form factor and exceptional processing speed, they are ideal for mid-to-large-scale control systems requiring precise motion, logic, and data management. The CJ2H-CPU66-EIP, in particular, offers 150K steps of user memory, making it suitable for complex programs with extensive data handling.
