7.3 Nominal current consumption of the modules
It is important to consider the current consumption of the individual modules for
power-feed, module protection and assessment of the voltage drop on the power
cable� The table below shows the nominal current consumption of the modules at
24 V DC� The sensor supply or the current for possible outputs has to be added�

7.4 Electrical isolation
7.4.1 Digital modules
In the digital input/output modules, the ground potentials (GND) of supply and load
voltage are connected�
7.4.2 Analogue modules
In the analogue input/output modules, these ground potentials are separated to
ensure the electrical isolation of the analogue signals from the operating voltage�
Should you use U
L
for feed-through, please make sure during connection
of a module without electrical isolation between U
B
and U
L
(e�g� all digital
modules) that the electrical isolation is neutralised by the feed-through of
U
L
�
7.5 Incoming line and power supply
The max� load applied to each of the connecting poins of all modules must not
exceed 4 A�
The following points have to be observed:
– Current consumption of the modules
(see Nominal current consumption → Chapter 7.3)
– Current consumption of the sensors
– Current consumption of the actuators
