4.19 Expandable bus controllers
The expandable bus controller is based on the POWERLINK bus controller X20BCx083. The bus modules expand-
ed to the left allow connection of up to two interface or hub expansion modules, depending on the bus controller.
Despite the sleek profile of only 62.5mm and 87.5, the bus controller contains the supply feed for the bus controller,
the X2X Link bus supply, and the I/O module feed. No additional power modules are necessary.
