The board is silkscreened with the designation DIGITAL I\/O and carries revision code 1\/86 RC. Each of the two mirrored sections provides 16 individually fused output channels, labeled FU1-0 through FU1-15, with a corresponding red LED indicator per channel for status monitoring. Field wiring connects via screw terminal blocks running the length of each section, numbered 1 through 32. DIP integrated circuits mounted near the top edge connector of each section handle signal processing, and dual high-density edge connectors interface directly with the Dynapath CNC backplane. The assembly number 502-03064-10 appears on a label in the lower portion of each section. The serial number visible on this unit is 220003. The solder side of the board shows a clean through-hole construction with no visible damage or rework in the available photos. This part is associated with Dynapath Delta and System 10, 20, and 30 series CNC controls. Sourcing references should include MPN 501-03855-00 and cross-reference assembly number 502-03064-10.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0326-823\u003c\/p\u003e","brand":"Dynapath","offers":[{"title":"Default Title","offer_id":48934690291952,"sku":"m00823","price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/64B68B5B-4C19-476A-B823-CF617E7EACE0.jpg?v=1772576312","url":"https:\/\/mroexchange.com\/products\/dynapath-digital-io-board-501-03855-00-0326-823","provider":"MRO Exchange","version":"1.0","type":"link"}
