Random Module Arrangement
The following overview shows the maximum number of channels possible, on condition that the entire
station is made up of that respective type of channel only:
Further limitations can be placed on the maximum possible number of BL20 modules by the use of the
Power Feeding modules BL20-PF-24VDC-D or BL20-PF-120/230VAC-D; these being used either for
creating potential groups or by insufficient field supply.

Attention
Ensure that a sufficient number of Power Feeding or Bus Refreshing modules are used if the
system is extended to its maximum.
Note
If the system limits are exceeded, the software I/O-ASSISTANT gen-erates an error message
when the user activates the "Station
→
Verify" command.
