The Omron CJ2H-CPU65 is the CPU unit of the CJ2H series, sized for mid-range machine control with 160K words of program memory. It supports up to 40 modules across three racks, giving room for substantial I/O and specialty modules without a larger controller. Built-in RS-232C and USB ports handle programming via CX-One and serial device connectivity. Battery backup protects user programs and retained data during power-down, so the CPU restarts with no external memory reload in most applications. The module mounts on DIN rail, operates from 0°C to 55°C, and carries CE, cULus, Lloyd, and NK approvals.
The listed approvals (CE, cULus, Lloyd, NK) cover the major marine and industrial safety standards. For internal compliance documentation such as RoHS or REACH declarations, request through the distributor – the approval listing is a strong indicator of full regulatory status.
