The 24 V DC contactor supply is not electrically isolated from
the 24 V DC supply of the power module, i.e. the 24 V DC
voltage is looped back in. There is voltage reversal and EMC
protection. Voltage dips are not buffered.
The 15 V DC slave supply is electrically isolated from the 24
V DC contactor voltage. Voltage dips are buffered up to at
least 10 ms. There is voltage reversal and EMC protection.
The subassembly contains an LED for indication of the 15 V
DC slave supply.
The 24 V DC contactor voltage that is looped back in is not
electrically isolated from the 24 V D supply voltage (AUX) of
the module. There is voltage reversal and EMC protection.
Engineering
Area of application of the SmartWire-Darwin power
module EU5C-SWD-PF2-1
• The supply for the slaves installed in the SmartWire
Darwin network is no longer sufficient (power
consumption > 0.7 A).
• 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 ( a section
"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.
