2.10.7. E-bus
The E-bus (X1) allows up to 7 E-bus subscribers to be connected to the Dialog-Controller. Please note that,
due to their function, some E-bus modules represent 2 E-bus subscribers, e.g., QDIO-E 16/16/Z2.

Category
CAT.5
Length
Max. 7 m
CAUTION
The Dialog-Controller makes a max. current of 0.5 A available for E-bus
modules!
As a rule, this is sufficient current to supply 7 E-bus modules. However, should
this current consumption level be exceeded, the E-bus and the connected
modules may become nonfunctioning!
Therefore, please note the current consumption of all E-bus modules and all
connected consumers as a whole. In some instances, connection of consuming
devices, e.g., an encoder can result in the current limit being exceeded.
Wherever possible you should only employ consumer devices with as low a
current requirement as possible!
2.10.8. Connections for expansion ports
NOTICE
