The SmartWire-Darwin power module EU5C-SWD-PF1 loops
the 24 V DC contactor voltage back into the SmartWire-
Darwin cable.
The looped back 24 V DC voltage is not electrically isolated
from the 24 V DC supply voltage (AUX) of the module. There
is voltage reversal and EMC protection.
Voltage dips are not buffered.
The subassembly does not need a diagnostics LED and no
diagnostics information of its own is sent on the SmartWire-
Darwin network. A fault in the 24 V supply voltage is
therefore ascertainable only via the missing voltage of the
downstream contactors.
Engineering
Area of application of the SmartWire-Darwin power
module EU5C-SWD-PF1-1
• The supply for the contactors installed in the SmartWire
Darwin network is no longer sufficient (power
consumption of the contactors > 72 W / 3 A).
• A selective emergency shutdown of individual contactor
groups or motor starter groups is required (
"Safety-related applications", page 46)
h
With a SmartWire Darwin power module a second
connection for the contactor coil control voltage can be
made at another position in the SmartWire Darwin
network.
