The board carries internal reference label M.1008.0300 and serial number A27056 as visible on the board edge. The PCB is configured as a single-axis servo interface card with dual power transistor assemblies (National Semiconductor LH0101CK) mounted on heatsink brackets, precision Dale RS-7 resistors rated at 10 ohms 0.05%, and multiple LM301A and LM8652 op-amp ICs. Silkscreen designations include GAIN, BAL, COS, RES, CMD, DRV, SIN, IND, FDBK, and GND signal points along the left edge connector, with SERVO CHAN and P1 CONN edge connectors at the bottom and right. The board also references resolver and feedback signal conditioning consistent with analog servo axis control in Giddings and Lewis CNC machine tool systems. Physical condition shows populated components with no visible signs of burning, cracking, or missing parts. This board is intended for replacement or spare use in compatible Giddings and Lewis CNC systems utilizing this servo interface assembly. Buyers are responsible for confirming compatibility with their specific machine configuration prior to purchase.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0226-551\u003c\/p\u003e","brand":"Giddings and Lewis","offers":[{"title":"Default Title","offer_id":48856895815920,"sku":"m00551","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/F2A3F701-8DD2-4EC9-BE84-4A89585AFA0B.jpg?v=1771631569","url":"https:\/\/mroexchange.com\/products\/giddings-lewis-servo-interface-circuit-board-501-03882-00-502-03092-00-0226-551","provider":"MRO Exchange","version":"1.0","type":"link"}
