Field-side termination is a D-Sub connector on the module face — the same gender and pitch convention used elsewhere in the CS1W comm line — so it lands in installations wired for serial CompoWay/F or Host Link drops rather than the RJ45 ethernet footprint of the ETN-series cards.","metaTitle":"Omron CS1W-SCU31-V1 Communications Module, CS Series","metaDescription":"Omron CS1W-SCU31-V1 CS1W-series communications module for CS Series backplanes, CE/cULus/Lloyd/NK, D-Sub field termination; sourced to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"Type":"Communications Module","Series":"CS1W","Weight":"0.551 lb (249.93 g)","Package":"Bulk","Mounting Type":"Backplane","Approval Agency":"CE, cULus, Lloyd, NK","lifecycle_stage":"eol_hot","Termination Style":"D-Sub","For Use With/Related Products":"CS Series"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$823.85 – $1,549.73","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/CS1W-SCU31-V1/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second source for the CS1W-SCU31-V1?","answer":"The CS1W-SCU21-V1 is the closest functional sibling in the same CS1W series — same backplane slot, same D-Sub termination, same CS Series host.
