QA6ADP Adapter with A Series AC Input Modules Technical Bulletin

This technical bulletin from Mitsubishi warns that when using a QA6ADP QA conversion adapter with A series AC input modules (AX10, AX11, AX11EU, AX20, AX21, AX21EU) on an A series extension base unit, an A series power supply module (A6P) is required. Without it, the CPU may falsely recognize an input signal as off when AC voltage drops below guaranteed levels, and provides two corrective measures involving replacing the base unit or adapter to mount the necessary power supply.
