The board provides dual-axis analog servo command output and feedback processing for CNC axis drives. Key components include a Burr Brown DAC811AH precision 12-bit digital-to-analog converter for servo command signal generation, a DALE XO-43B 16.384 MHz crystal oscillator, an LM339N quad comparator, a DG212CJ precision analog switch, Maxim ICs, and an IM6116CPI static RAM. Logic devices throughout include MC74HC and MM74HC series ICs. A sub-board at position N1 is labeled 502-52984-00 \/ 89212-00. PASS and FAIL status LEDs provide onboard diagnostic indication, and STR and ZERO test points are present for calibration. The board is populated on a gold-tinted FR4 substrate with yellow SMD capacitors and resistor networks throughout. The Dual Servo SBX interfaces with the main CNC control board to deliver precise analog velocity or torque commands to two servo drives simultaneously. With the G\u0026amp;L 8000 platform at end-of-life status per Fives, servo SBX boards are actively sought by facilities maintaining legacy Giddings and Lewis horizontal boring mills and vertical turning centers.\u003c\/p\u003e\n\u003cp\u003eStock # 0226-518\u003c\/p\u003e","brand":"Giddings and Lewis","offers":[{"title":"Default Title","offer_id":48856688525552,"sku":"m00518","price":599.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/7F6D7102-5E4B-4D78-8343-D0D231B6573B.jpg?v=1771624722","url":"https:\/\/mroexchange.com\/products\/giddings-and-lewis-dual-servo-sbx-board-502-03423-01-0226-518","provider":"MRO Exchange","version":"1.0","type":"link"}
