The Mitsubishi QY221B with PCB number BN634A564G52 is an industrial operator panel board for CNC control systems. The assembly is used within the machine operating and control system to process and transfer inputs and signals from the operator panel.
This board was removed from a Deckel Maho DMC 70 V. The QY221 series is assigned to the operator panel section of Mitsubishi MELDAS CNC systems and, depending on the machine and control configuration, may also be used in conjunction with Deckel control systems.
The PCB is equipped with several multipole connectors, a 25-pin D-sub connector, electronic memory and control components, and two coding switches. When replacing an existing board, particular attention should be paid to the complete QY221B type designation, PCB number BN634A564G52, component layout and the installed software or EPROM markings.
The item is used and in good visual condition. It is suitable for maintenance, repair and spare parts stock for CNC machining centres and industrial control systems.
Compatibility Notice:
Before purchasing, please compare the QY221B designation, PCB number BN634A564G52, EPROM markings, connector positions and coding switch settings with your existing board and machine or control documentation. Different control and PCB versions may be installed within the same machine series.
