ATTENTION: The 1203 flex modules that use this base may
require up to twice the adapter power supply current of standard
flex modules. When installing flex modules, you can use a

of the standard flex modules, so you cannot install as many
standard modules as you normally would when using the 1203
modules. Refer to the following chart to determine the number of
1203 and standard modules that may be installed together in your
system.
