The NJ501-1400: EtherCAT and EtherNet/IP are on board; no option card needed for the main fieldbus. USB is also there for quick program download via SYSMAC Studio. Memory allocation: 20MB program, 4MB data, 6MB variable retention. Battery backup holds variables for 5 years at 25°C, so include a battery swap in the maintenance schedule around year 4.
Lifecycle status is Active — no end-of-life notice, no LTB clock. This part sits comfortably in the current catalog for new machine builds and panel refreshes. Compliance: CE, cULus, KC, Lloyd, NK. Also meets IEC 61010-2-201 pollution degree 2. That covers most global CE and UL panel requirements out of the box.
Mounts on DIN rail, operates 0–55°C. Grounding requirement is <100 Ohms — typical for a machine controller chassis. No display, so all configuration is through SYSMAC Studio over USB or Ethernet. The 2560 local I/O point limit and 40-module expandability let you centralize control for a large machine zone. If you need fewer I/O, the lower-end NJ501 models may save panel space, but this one gives headroom for future expansion without a backplane swap.
