2.3 Limit / maximum expansion of the ET 200pro modules that can be
connected
Maximum expansion for each IM 154 interface module
When configuring the system, please note the following:
● One ET 200pro station can be configured with up to 16 modules for each IM154 interface
module. These include:
–
Power modules
– Frequency converters
– Electronic modules
– Motor starters and special modules
● Up to 5 frequency converters can be mounted into one ET 200pro station.
● The maximum width of an ET 200pro is 1 m.
I/O address range of the ET 200pro frequency converters
The address range is 4 bytes.
Current carrying capacity of a 24 V potential group
The number of modules that can be connected depends on the total current of all of the
modules of this potential group. This total may not exceed the maximum current carrying
capacity.
Note
The current consumption of a frequency converter is max. 0.8 A.
If additional components belong to a particular potential group, e.g. a motor starter, then the
current consumption of this component must be separately taken into account.
Current carrying capacity of a 400 V load group
The total capacity of a load group (sum total of currents of all the loads in a load group) is
25 A (3 AC 400 V). If this value is exceeded, a new load group is required. With the
frequency converter it is possible to relay the 400 V power supply to the next frequency
converter/motor starter in the ET 200pro station.
