COMPACT modules

11.1 What do COMPACT modules offer?
11.1
COMPACT modules combine the functions of an interface module with the functions of a
digital electronic module. In combination with a terminal module TM-C and a terminating
module, the IM151-1 COMPACT constitutes a complete slave.
Characteristics of the COMPACT module
• The familiar ET 200S handling also applies to COMPACT modules (mounting, wiring,
• Also, an ET 200S configuration with only one COMPACT module must be connected to
• The IM151-1 COMPACT can be expanded with up to 12 peripheral modules, with the

The expansion can be undertaken without additional power modules, if the maximum
load in the final voltage groups is not exceeded. The peripheral modules are supplied via
the backplane bus from the final voltage group. The total current may not exceed 5 A.
