VersaPoint Power Consumption Example

When configuring a VersaPoint Station it is important to consider the current
requirements of each module in the I/O system. These current requirements are
described in the module-specific data sheets. As noted previously:
If the current load limit is reached at U
inserted
If the current load limit is reached for U
must be built using a new Network Interface Unit.
The following example shows how the current consumptions of a VersaPoint I/O
station can be determined. It also provides insight into the requirement for
additional I/O terminals.
Consider an application which requires the following VersaPoint modules:
Catalog Number
IC220MDL721(Qty 3)
IC220MDL751
IC220MDL752
IC220MDL641(Qty 2)
IC220MDL644
IC220ALG620
IC220PWR014
Using the information on current consumption in the module datasheets, the
following current consumption table can be generated:
