VFD IO expansion card
A-slot expansion card (standard), B-slot expansion card (optional)
The VH6 series frequency converter comes standard with an A-slot IO expansion card at the factory, with configuration functions and terminal numbers that can meet most applications. When the functions or number of output terminals of the standard A card cannot meet the application requirements, users can choose to select a B slot IO expansion card.
