The 300 and 312 interface modules are used for centralized connection of
I/O modules and signal preprocessing modules (IPs) to a CC via the
following expansion units (allowing for possible configurations):

EU 183U

EU 184U

EU 185U (only input/output modules)

EU 187U

ER 701-1

Additionally, you can utilize these IMs for secondary communication, i.e.
additional EUs can be connected in a centralized arrangement to an EU 183U
or EU 185U in distributed configuration. Up to four IM 300s can be used in
one CC, up to two of which may be IM 300-5s. You can use one IM 300 in
an EU 183U or EU 185U.

An IM 300 EU interface module is complemented by an IM 312 or
IM 306 CC interface module. Use the following IMs, depending on the
connected EU:

IM 300-5 C 
(6ES5 300-5CA11)

EU 184U, EU 187U

IM 312-5

IM 300-3 
(6ES5 300-3AB11)

EU 185U (only I/O 
modules)
