Attention!
Risk of irreparable damage to the device!
U
S
and GND must not be interconnected with the corresponding
terminals of another device.
Never supply sensors connected to the inputs of the analog
input module (E1...E4) from the supply terminals U
s
and GND
of a connected EIB device.
Power supply of connected sensors
GB
•
The connected sensors can be supplied from terU
S
and
GND (see fig.
c
). These terminals are provided in duplicate and
internally interconnected.
•
The total current consumption of all sensors supplied this way
must not exceed 100 mA.
•
In the event of overload or short-circuit bU
S
and GND,
the power will be switched off. After removal of the fault, the
power is switched on again automatically.
•
Sensors connected can also be supplied externally (e. g. if their
current consumption exceeds 100 mA). In such case, they must
be connected between terminals E1...E4 and GND.
