A Fast Input SBX Board from Giddings and Lewis, part number 502-03421-00, serial number E23897, date code 489901. This circuit board is a plug-in SBX format module designed for use within Giddings and Lewis PLC and CNC control systems. The SBX architecture was used extensively in Giddings and Lewis 8000 series CNC platforms, where discrete input modules like this one handled high-speed or fast input signal processing tasks. The board features a card-edge connector at the base, consistent with the SBX slot form factor, and is packaged in an ESD-protective antistatic bubble bag as indicated by the static-sensitive device warning labels. Note that 502-series catalog numbers are associated with the Giddings and Lewis 8000 CNC control system, and per published cross-reference information, 572-series numbers are equivalent to their 502-series counterparts. This module is a static-sensitive electronic assembly and must be handled with appropriate ESD precautions. Voltage and signal specifications are not confirmed from visible label data.
