Sumitomo Electric Industries, Ltd. AS-3210 Main Board

Sumitomo Electric Industries' AS-3210 Main Board is the central industrial-control PC board used in Sumitomo automation systems. The model is commonly referenced simply as AS-3210, with documented revisions such as REV.D in secondary-market listings, signaling an established lineage within the AS-3210 family. In reseller catalogs, the board is described as a PC Board suitable for PLC applications and, in some cases, as an add-on board compatible with MIS (Sumitomo-related) assemblies, underscoring its role as a module rather than a consumer PC motherboard. Market availability often appears on platforms like eBay and Radwell, reflecting its status as a used or surplus industrial component rather than a current-off-the-shelf product. Buyers sourcing this part typically verify suitability against the exact Sumitomo equipment and the seller’s datasheet or product notes to ensure proper fit, pinout, and integration with the control-system wiring harness.
