needs.Select one or a combination of the methods to power the
signalsof each of your I/O modules:
• Thesignals of the I/O module are powered by an FP-PS-4 that
isconnected to only that I/O module.
• Thesignals of the I/O module share an FP-PS-4 with a
neighboringI/O module or network module. This is called
cascadingpower.
Caution Cascadingpower from neighboring bases o r
networkmodules defeats isolation between cascaded
modules.
Figure6 shows a combination of the two ways to power the
FieldPointbank.
Figure6. WiringPower to Your FieldPoint Bank
InFigure 6, the FP-PS-4 bank provides the power using both of the
methodsmentioned previously.The FP-2000 and FP-AO-200 have
theirown power supplies. Isolation is maintained because the
FP-AO-200has its own power supply. The FP-RLY-420and
FP-DO-400share a power supply, which provides enough power,
butdefeats isolation between the signals of those two modules.
