needs. Select one or a combination of the methods to power the

signals of each of your I/O modules:

• The signals of the I/O module are powered by an FP-PS-4 that

is connected to only that I/O module.

• The signals of the I/O module share an FP-PS-4 with a

neighboring I/O module or network module. This is called

cascading power.

Caution

Cascading power from neighboring bases or

network modules defeats isolation between cascaded

modules.

Figure 6 shows a combination of the two ways to power the

FieldPoint bank.

Figure 6. Wiring Power to Your FieldPoint Bank

In Figure 6, the FP-PS-4 bank provides the power using both of the

methods mentioned previously. The FP-2000 and FP-AO-200 have

their own power supplies. Isolation is maintained because the

FP-AO-200 has its own power supply. The FP-RLY-420 and

FP-DO-400 share a power supply, which provides enough power,

but defeats isolation between the signals of those two modules.
