The UR2-H rack is used for assembling two central racks or expansion racks in
one rack. The UR2-H rack essentially represents two electrically isolated UR2
racks on the same rack profile. The main area of application of the UR2-H is in the
compact structure of redundant S7-400H systems (two subracks or subsystems in
one rack).

You can use the following modules in the UR2-H rack:

When the UR2-H is used as a central rack:

•

All S7-400 modules with the exception of receive IMs

When the UR2-H is used as an expansion rack:

•

All S7-400 modules apart from CPUs, send IMs, the IM 463-2, and the adapter
module

Special case: Power supply modules cannot be used in conjunction with the
IM 461-1 receive IM.

Figure 2-3 shows the structure of the UR2-H rack with 2 x 9 slots.
