Giddings & Lewis and Lewis Servo Nest Power Board 502-03429-00

The Giddings and Lewis 502-03429-00 is a Servo Nest Power Board designed for use in Giddings and Lewis CNC control systems. The unit is identified by its original OEM label, which shows part number 502-03429-00, serial number E24549, and date code 020001. The item is manufactured by Giddings and Lewis, a well-established US builder of machine tool controls and CNC systems known for heavy-duty horizontal boring mills, machining centers, and transfer line equipment.

The board is packaged in an anti-static shielded bag with ESD warning labels visible on both sides, consistent with standard handling requirements for sensitive electronic assemblies. The label confirms the description "Servo Nest Power Board," indicating this PCB provides power distribution or regulation within a servo nest enclosure as part of a larger CNC motion control system.

Giddings and Lewis servo nest components are used in machines where the control architecture separates servo power and signal processing into modular nest assemblies. The 502-03429-00 is specific to that architecture and is sought by maintenance and service teams supporting legacy G and L controlled equipment. Voltage specifications are not visible on the nameplate and could not be confirmed from the photos provided.
