A secondary PCB identifier, 502-03423-01, is also printed on the board and may represent an assembly or schematic reference number. The board is a full-length, multi-layer design populated with a dense array of through-hole integrated circuits including Harris CMOS logic, National Semiconductor HC-series logic, and a DAC811AH digital-to-analog converter. A DALE crystal oscillator marked XO-43B at 16.384 MHz is mounted on the component side, and a gold-lidded ceramic IC package is visible near the oscillator. The board features a card-edge connector on one end and a 40-pin ribbon cable connector populated with a blue IDC header. The designation \"DUAL SERVO SBX\" indicates the board is intended for dual-axis servo interface functions within a CNC or industrial automation control system. The assembly number 501-04309-01 is the primary market-recognized identifier for this board. Revision 1 is silkscreened directly on the PCB. The manufacturer is not identified by visible logo or marking on either side of the board.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0326-519\u003c\/p\u003e","brand":"Giddings \u0026 Lewis","offers":[{"title":"Default Title","offer_id":48856676172016,"sku":"m00519","price":599.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/07978DE8-BBF4-4BFF-9335-FFDECD38ABE3.jpg?v=1771624428","url":"https:\/\/mroexchange.com\/products\/giddings-lewis-dual-servo-sbx-board-501-04309-01-0326-519","provider":"MRO Exchange","version":"1.0","type":"link"}
