The board features two independent I\/O sections, each populated with a full complement of screw-terminal terminal blocks, individual fused output circuits (FU1 series), red LED status indicators for each I\/O channel, jumper pin headers, and a card-edge connector for backplane interface. PCB silkscreen labeling identifies discrete numbered I\/O points across both sections, with INPUT and OUTPUT zones clearly marked. The board carries the Giddings and Lewis Electronics logo and includes a Board Section label area on each half. Construction is through-hole and mixed surface mount on a green FR4 substrate. This type of board provides discrete digital signal interfacing between machine field devices and the CNC control processor. The G\u0026amp;L 8000 control platform has reached end-of-life status per Fives, making spare boards such as this one increasingly difficult to source for facilities maintaining legacy Giddings and Lewis horizontal boring mills, vertical turning centers, and other G\u0026amp;L CNC equipment. No voltage rating, revision level, or serial number was confirmed from the provided photos.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0226-507\u003c\/p\u003e","brand":"Giddings and Lewis","offers":[{"title":"Default Title","offer_id":48856377458928,"sku":"m00507","price":499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/49416141-85A4-4BB1-8B53-CF81AE9F50F7.jpg?v=1771620601","url":"https:\/\/mroexchange.com\/products\/giddings-and-lewis-digital-io-board-502-03064-00-0226-507","provider":"MRO Exchange","version":"1.0","type":"link"}
