3.3 System overview
The extensions can be connected to the controller through the RS-485 extension module
bus. A maximum of three IO extensions can be connected to one controller.
The extension must be addressed accordingly (1-3).
In the example, the power is supplied via the controller. If necessary, it is also possible to
use a separate power supply for an extension.
