The board description \"Diff Encoder Interface\" is silkscreened directly on the green PCB in yellow text, consistent with Giddings and Lewis CNC control system conventions. This type of interface board is used in Giddings and Lewis CNC machine tool control systems to process and route differential encoder feedback signals, supporting closed-loop servo axis control. Giddings and Lewis, later operating under the Danaher Motion and Kollmorgen umbrella, produced CNC control systems for large-format machining centers, boring mills, and turning centers, where encoder interface boards such as this served as critical system components. The 502-03733-00 assembly number also appears as the reference number on a later Danaher Motion labeled unit of the same design, indicating cross-platform use across control generations. This board has been discontinued by the manufacturer and is offered as surplus. No voltage rating or additional electrical specifications are visible on the board or label. Buyers should verify compatibility using the part number and assembly number prior to purchase.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0226-386\u003c\/p\u003e","brand":"Giddings and Lewis","offers":[{"title":"Default Title","offer_id":48833910833392,"sku":"m00386","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/69784521-A86B-46E3-9D0F-202CA657B949.jpg?v=1771295685","url":"https:\/\/mroexchange.com\/products\/giddings-and-lewis-differential-encoder-interface-pcb-assembly-501-04758-00-0226-386","provider":"MRO Exchange","version":"1.0","type":"link"}
