MELSEC-Q and MELSEC-QS Series Serial Number Printing Technical Bulletin

This technical bulletin from Mitsubishi announces that serial numbers will be printed on the front face and package label of MELSEC-Q and MELSEC-QS series modules for easier identification. It lists specific module models (e.g., QCPU, A/D converter, positioning modules) and their corresponding shape changes, noting that serial number printing may not be present on all modules immediately due to phased production implementation.
