What it is and what it does
The Omron CJ1W-NC481 is a 4-axis motion control module built for the CJ Series PLC platform. It terminates over RJ45 for the motion bus, mounts on a DIN rail, and operates from 0°C to 55°C. CE and cULus approvals cover the usual panel and machinery export routes.
How it compares to the close siblings
The CJ1W-NC482 shares the NC481's 4-axis control, RJ45 termination, and DIN rail mount; the CJ1W-NC434 requires 24VDC and a rectangular connector.
Panel fit and integration notes
DIN-rail footprint, RJ45 termination — plan for a clean motion bus cable run. The 0°C to 55°C ambient covers most cabinet environments without forced cooling. CE and cULus mean it passes the compliance gate for EU and North American builds. No separate 24VDC supply needed; the module draws its power from the CJ-series backplane.
