Maximum current consumption of
the I/O modules See chapter 5 and the module datasheets
Observe the logic current consumption of each device when configuring a
VersaPoint station! The logic current consumption is indicated in chapter
5 and in each module data sheet. The current consumption can differ
depending on the individual module. The permissible number of devices
that can be connected depends on the specific station structure.

Observe the current consumption of every device on the individual voltage
jumpers when configuring a VersaPoint station! The logic current
consumption is given in chapter 5 and in each module data sheet. The
current consumption can differ depending on the individual module. If the
maximum current carrying capacity of a voltage jumper (8A) is reached, a
new power terminal must be used.
