Interface Modules

7.1The 300 and 312 Interface Modules

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):

SEU 183U

SEU 184U

SEU 185U (only input/output modules)

SEU 187U

SER 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.

Application of the An IM 300 EU interface module is complemented by an IM 312 or

IM 300 and IM 312 IM 306 CC interface module. Use the following IMs, depending on the connected EU:
