Understandably,  when  you  look  at  the  complete  list  of  different types 
of 
input, 
output,  and special function module available for the AIS, it can seem a difficult 
task to choose what you require for your application. But don't worry, the reason for 
all the  different types  of  module  is 
so 
the  AIS can  be  used  for  all  types  of 
application. All you have 
to do is simply calculate the number 
of 
different types of 
input and  output  to  be  used  in your  application,  and  select the  right type  and 
number of modules from the list. The only other things to consider then are that you 
need  a 
CPU 
module,  power  supply  module,  and  base  units to  hold  all  of  the 
modules you have selected. Also choose the programming device you want to use 
for the creation of your sequence program.

The  AIS 
PLC 
is  primarily  designed  for  installation  inside  electrical  cabinets, 
however it can 
be 
installed in other places if adequate protection to dust, water, oil 
etc..  is made.  Because of its micro modular design it takes up very little space and 
can be fixed 
on 
to 
DIN 
rail using the fixing attachments already  installed on the 
back of the base units. Alternatively, the  base units can be fixed in to place using 
the screw holes provided on each of its corners.
