Omron NJ501-4300 machine automation controller CPU, built for 16-axis synchronized motion control over EtherCAT. The processor runs 32K words of logic and supports expansion up to 40 modules across 3 racks, programmed via SYSMAC Studio. Rated 0–55°C with CE, cULus, Lloyd, and NK approvals.
What the key ratings mean for fit
32K word memory drives 16-axis motion over EtherCAT; Ethernet and USB ports handle programming and data exchange. Battery backup retains logic and encoder positions on power loss. The CPU mounts on DIN rail with no integrated display – all configuration and diagnostics go through SYSMAC Studio over USB or Ethernet. Power to the CPU comes from the NJ-series power supply unit (sold separately); the CPU itself does not include a power supply. Approvals CE, cULus, Lloyd, and NK cover European, US, and marine (shipbuilding) environments. If your panel targets a RoHS or REACH zone, verify that the specific batch documentation covers your requirement – the listed approvals do not explicitly include those.
