2.7.7. E-Bus
The E-bus (X1) allows up to seven E-bus subscribers to be connected to the
DIALOG CONTROLLER. Please note that, due to their function, some E-bus mod-
ules represent two E-bus subscribers, e.g., QDIO-E 16/16/Z2.

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 seven 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 con-
nected consumers as a whole. In some instances, connection of consuming de-
vices, e.g., an encoder can result in the current limit being exceeded.
Wherever possible you should only employ consumer devices with as low a cur-
rent requirement as possible!
2.7.8. Connections for Expansion Ports
Device connection
Prior to connecting any external devices, please carefully read the documentation
included with these devices.
Always hold a lead by the plug when connecting or disconnecting a device. Never
pull on the lead itself!
The connection level for all external devices is located on the rear of the DIALOG
CONTROLLER. All connections are plug-in.
