Giddings and Lewis Electronics Servo Interface PCB circuit board, part number 501-03882-00, assembly number 502-03092-00, revision RC dated 5/84. This single-axis servo interface board was designed for use in Giddings and Lewis CNC machine tool control systems and carries silkscreen labeling identifying GAIN, BAL, IND, COS, RES, CMD, SIN, FDBK, and GND signal connections along the left edge connector, consistent with an analog resolver-based servo feedback interface. The board features two TO-3 package power transistors marked S8504 LH0101CK, dual LM301 op-amp ICs, precision resistors rated 10K 0.05%, and a range of passive components throughout. Two 20-pin edge connectors (P1 and P2) are present, and the board carries a Giddings and Lewis Electronics logo. Serial number 527404 is visible on the board face. Revision code RC and date code 5/84 indicate a 1984 production date. This board is suitable for use in Giddings and Lewis CNC systems requiring a compatible single-channel servo interface card. The board shows age-consistent patina consistent with removed surplus equipment.
