It is built for the CJ platform — the same chassis family used across a long line of CJ-series CPUs and I/O — so it drops into the existing slot pattern of a CJ backplane without rewiring the rack. ## Ratings and approvals that govern the panel The module carries CE, cULus, Lloyd, and NK approvals, which covers the typical jurisdictions for a control panel: North America via cULus, Europe via CE, marine class via Lloyd, and Japanese vessel class via NK. At roughly 93.89 g it is light enough that DIN-rail mounting is the only mechanical story — no panel-cut or stud-mount provisions to design around. ## Lifecycle posture The factory lifecycle entry reads Active, while the commercial field is flagged eol_hot — a known mixed signal on this code that buyers should verify before committing a long-running BOM line. Because the status is split, treat the part as quotable to order against an RFQ and confirm availability on a per-build basis rather than assuming indefinite factory production.","metaTitle":"Omron CJ1W-EIP21 EtherNet/IP Module, CJ Series","metaDescription":"CJ1W-EIP21 is a CJ-series communications module with DIN-rail mounting and RJ45 termination, CE/cULus/Lloyd/NK approved; lifecycle flag EOL/hot — quote to RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"Type":"Communications Module","Series":"CJ1W","Weight":"0.207 lb (93.89 g)","Package":"Bulk","Mounting Type":"DIN Rail","Approval Agency":"CE, cULus, Lloyd, NK","lifecycle_stage":"eol_hot","Termination Style":"RJ45","For Use With/Related Products":"CJ Series"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$412.00","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/CJ1W-EIP21/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to CJ1W-EIP21?","answer":"The CJ1W-ETN21 is the closest functional same-class alternative within the CJ series: it shares the DIN-rail mount, RJ45 termination, and CJ-platform footprint, but runs standard Ethernet services rather than EtherNet/IP on the wire."},{"question":"What is CJ1W-EIP21's listed type?","answer":"It is listed as a Communications Module for the CJ Series platform."},{"question":"What compliance documentation ships with CJ1W-EIP21?","answer":"The module is approved to CE, cULus, Lloyd, and NK — covering North American, European, and marine-class jurisdictions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/CJ1W-EIP21","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/CJ1W-EIP21 when reusing this data.
