This single-axis servo interface board was designed for use in Giddings and Lewis CNC machine tool control systems. Silkscreen labeling along the edge connector identifies GAIN, BAL, IND, COS, RES, CMD, SIN, FDBK, and GND signal points, consistent with an analog resolver-based servo feedback interface architecture. The board features two TO-3 package power transistors marked S8848 LH0101CK, dual op-amp ICs including LM301 and M9444 types, precision resistors rated 10K 0.05%, RS-7 precision resistors rated 10 ohm 0.05%, and a full complement of passive components. Two 20-pin gold edge connectors (P1 and P2) are present for system integration. The Giddings and Lewis Electronics logo is silk-screened on the board face. Serial number 522704 is visible. Revision code RC and date code 5\/84 indicate a 1984 production date. This board is intended for use in Giddings and Lewis CNC systems requiring a compatible single-channel analog servo interface card. The board shows age-consistent patina typical of removed surplus equipment.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0226-563\u003c\/p\u003e","brand":"Giddings and Lewis Electronics","offers":[{"title":"Default Title","offer_id":48884973961456,"sku":"m00563","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/1D47203C-33BC-40F7-A3B3-C944ED427619.jpg?v=1771862690","url":"https:\/\/mroexchange.com\/products\/giddings-and-lewis-servo-interface-pcb-circuit-board-501-03882-00-0226-563","provider":"MRO Exchange","version":"1.0","type":"link"}
