Giddings and Lewis EIA-CL Convertor Circuit Board, assembly number 501-03377-00, schematic number 502-02918-00, manufactured by Giddings and Lewis Electronics. The board is a large-format double-sided PCB with gold-fingered edge connectors on both the left and right sides for backplane installation. The board revision date code RD 3.81 is silkscreened on the component side along with a SERIAL NO. designation, though the serial number field is blank in the available photos. A 12-position screw terminal block labeled 1TB provides field wiring connections for power and signal lines including +15V, GND (three positions), -15V, Current Loop + Input, Current Loop Output, Current Loop Input, Current Loop + Output, EIA Input, and EIA Output. Additional visible components include two optocoupler assemblies (MC1 and MC2), a red DIP switch array with 8 positions at position 13, small signal transistors, diodes, and resistors. The board functions as an EIA to current loop serial communications interface converter within Giddings and Lewis CNC machine tool control systems. All components appear visually present with no visible signs of burning, cracking, or physical damage. Buyers are responsible for confirming compatibility with their specific machine configuration prior to purchase.
