Base modules XC-ADP/XC-ADP-XION
General
A base module and a power supply module form one unit. The
possible combination of both modules can be found in table 1. The
modules differ in their capability for expansion with signal
modules.
A base module is the platform on which additional function
modules can be built up, in a stack. The complete unit is then fitted
on the mounting rail.
Task of the XC-ADP module
This is used as a platform to build on additional modules.
Tasks of the XC-ADP-XION module
The module conveys the signal data bus and the supply voltage
(5 V) from the power supply module to the signal modules.
The base module has a separate connection for the 24 V DC field
power supply of the XI/ON modules. It also has a C connection to
which the potential for the C rails of the XI/ON modules can be
connected.
Guidelines for using XI/ON signal modules to expand the controller
are provided in the XI/ON manuals, e.g. “Hardware and
Engineering”, AWB2700-1394-GB.
Project engineering for the base module XC-ADP-XION
Power supply for the XI/ON modules
The 24 V DC power supply required to feed the XI/ON modules is
connected to the base module (
a also “Power supply module”).
The maximum current drawn is 10 A.
Connections
The C1 connection is routed to the XI/ON modules. It is used to
establish an additional common potential, e.g. for the protective
earth PE.
XI/ON modules that have a C in their designation, e.g. S4T S-B-C-
S, require the provision of a common C rail.
