This listing is for a Giddings and Lewis Electronics Digital I/O PCB Board assembly, part number 501-03855-00, with secondary reference number 502-03064-10 visible on an affixed label. The board is date coded 7/83 RB. The assembly consists of two mirrored Digital I/O sections, each with labeled INPUT and OUTPUT edge connectors, 16 screw terminal input positions per section numbered 1 through 28 visible in photos, individual fuse positions labeled FU1-0 through FU1-13 per section, and individual LED indicator positions labeled LED1-0 through LED1-13 per section.

This Digital I/O board is consistent with components used in Giddings and Lewis CNC control systems commonly found in machining centers and other industrial machine tool applications from the 1980s. It represents a dual-section I/O interface assembly providing fused discrete input and output channels with individual LED status indication per channel.
