Choosing Termination Assemblies
The use of termination assemblies gives the AADvance system exceptional flexibility
for creating different architectures and expanding the system. Each termination
assembly is a very simple circuit that is matched to a type of I/O module and to a
particular module configuration. This table shows a summary of the termination
assemblies which are available and the associated I/O module configurations.

IMPORTANT: The termination assemblies for inputs accommodate 8-channel I/O
modules and 16-channel I/O modules. A dual or triple arrangement can be made of 8-
or 16-channel modules, but not a mixture of the two.
You need one termination assembly for each group of associated modules. For
example:
 Four T9401 digital input modules used in two, dual redundant configurations need
two T9802 termination assemblies — one for each pair of modules
 Four T9401 digital input modules used for simplex inputs need four T9801
termination assemblies — one for each module
Specify I/O Base Units
The T9300 I/O base unit (3 way) is a single, standardized design which suits all
termination assemblies and I/O modules. The base unit can accommodate one triple
modular redundant assembly, one dual assembly and one simplex assembly or up to
three to simplex assemblies. The dual and triple modular redundant assemblies can
bridge adjacent base units, so two base units can (for example) hold three dual
assemblies.
