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.
Sourcing & Lifecycle
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.
