What it is
The Omron CS1D-BC082S is a CS1D-series backplane accessory built for the CS1 Series PLC platform, packaged in bulk and listed as a redundant network rack for CPUxxS modules. It sits in the same accessory family as the other CS1D backplanes, carrying no I/O of its own — the rack is the mechanical and bus backbone the CPU, power supply and I/O units mount onto.
Lifecycle and sourcing posture
The listing carries eol_hot, which signals a hot end-of-life posture rather than routine production — the rack is still moving through the channel but the factory-side runway is narrowing. With no last-time-buy date on the record, the working assumption for a BOM line is to spec it now and quote to order against an RFQ, since independent surplus is typically what fills gaps once the official line tapers. The productStatus entry reads Active, which sits alongside the eol_hot stage flag — meaning the part is orderable today but should be spec'd with phase-out timing in mind for multi-year panel builds.
Sourcing takeaway
For a CS1D redundant CPU build, the CS1D-BC082S is the correct rack to quote when the slot count matches the I/O and CPU population on the BOM. Given the eol_hot flag, the cleanest move is to lock the order against an RFQ now — specifying the CS1D series, the CS1 Series compatibility, and the bulk package so the quote returns with confirmed availability rather than a generic catalog line.
