OPOLOGIES
There are three ways in which to distribute 24VDC power to loads in your
machine, and each topology has its own pros and cons. The following is a
brief description of each wiring method.
•
Daisy-chained
24VDC power from the eF-785 is connected to
the first load in the chain; power from the first load is connected
to the second load, and so on. This is the simplest wiring topology
available, but does not have the redundancy and lower resistance
that the Daisy-chained loop topology offers.
Daisy-chained wiring topology
•
Daisy-chained loop
This topology is similar to the daisy-
chained wiring described above, the difference being that the
“last” load in the chain is connected back to the eF-785. This type
of wiring offers the advantages of not only being redundant
should one of the cables delivering power to the loads become
open or intermittent, but addition of another power-carrying
cable supplying the loads lowers supply-to-load resistance (and
subsequently the I
2
R power loss in the cabling). This parallel
power path provides improved machine performance and
reliability.
