This board carries part number A20B-0008-0540 with revision \/01A and board reference A350-0008-T544\/01, both of which are visible on the PCB silkscreen. Manufactured by Fanuc in Japan, it is populated with standard TTL-family logic ICs including HD74LS174P devices and SN7406N buffers, consistent with the discrete I\/O architecture used across the Fanuc 6 series control platform. Published specifications for this board indicate a capacity of 96 discrete inputs and 64 discrete outputs. The board fits the standard Fanuc 6 series card cage format and interfaces with the control backplane through edge connectors. It is a known direct replacement for the earlier A20B-0007-0040 board. The board is mounted in a gold-anodized aluminum carrier frame with standard card-cage slot hardware. Compatible controls include the Fanuc 6M and 6T series. Part number A20B-0008-0540 is the OEM market-recognized identifier used consistently in active US industrial surplus listings for this assembly.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0226-632\u003c\/p\u003e","brand":"Fanuc","offers":[{"title":"Default Title","offer_id":48890700824816,"sku":"m00632","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/10817B9B-1753-420C-8DD3-CF78254D71B7.jpg?v=1771952141","url":"https:\/\/mroexchange.com\/products\/fanuc-io-interface-board-a20b-0008-0540-0226-632","provider":"MRO Exchange","version":"1.0","type":"link"}
