Mitsubishi Electric Q38B Base Rack Backplane Unit

The Mitsubishi Electric Q38B Base Rack Backplane Unit is a MELSEC-Q Series backplane designed for the base rack, enabling eight-slot configurations to organize and connect installed modules within a single chassis. Identified by the Q38B part number and belonging to the QnU family, this backplane provides the fixed interconnect within a compatible MELSEC-Q Series base rack to link the main controller with the eight module slots. With eight slots, the backplane consolidates module mounting in a single chassis, supporting orderly wiring and consistent signal routing across the installed I/O and expansion modules. Use this backplane in MELSEC-Q Series systems to host eight modules within a single base rack and maintain a clear, organized installation.
