Wiring Power to the FieldPoint System

Cascading power defeats isolation between the cascaded modules.

Each FP-20xx on your network requires an 11–30 VDC power supply.
The FP-20xx filters and regulates the supplied power and provides power
for all the I/O modules in the bank. This power is sufficient for most
FieldPoint I/O modules. Refer to the documentation for the individual I/O
modules to determine whether they require any additional power in your
applications.
Figure 2-1 shows the 6-pin screw-terminal power connector on the
FP-20xx.

Follow these steps to connect power to the FieldPoint system:
1. Connect the primary power supply to the center V and C pair. You
can connect an optional backup power supply to the left V and C pair.
The FP-20xx uses the power supply with the higher voltage level.
The V terminal for backup power is isolated from the other
V terminals. The right V and C pair provides a convenient means of
connecting power to the V and C terminals of a terminal base.
Figure 2-2 shows this optional connection, called
To verify that your power supply is sufficient for your modules and
devices, refer to the
for instructions on calculating power requirements.
2. Connect power to the FieldPoint modules that require external power
for inputs or outputs (may include output modules, counter modules,
PWM, PG, QUAD). Refer to the I/O module's operating instructions
