OPERATING INSTRUCTIONS
FP-PS-4
FieldPoint Power Supply
These operating instructions describe the installation, features, and
characteristics of the FP-PS-4.
Features
The FP-PS-4 is a FieldPoint power supply module with the
following features:
• 24 VDC output
• Convenient DIN rail mounting or optional panel mounting
• Universal AC power input: 90 to 264 VAC, 47 to 63 Hz
• Modular FieldPoint form factor for easy integration with other
FieldPoint modules
• 15 W output for 0 to 50 °C operation
Installation
You can mount your FieldPoint system either to a DIN rail or
directly on a panel. The following sections give instructions for
both mounting methods.
Mounting Your FP-PS-4 on a DIN Rail
The FP-PS-4 power supply module has a simple rail clip for
reliable mounting onto a standard 35 mm DIN rail. Follow these
steps to mount the module on a DIN rail.

3. Slide the FP-PS-4 to the desired position along the DIN rail.
For maximum cooling, leave a 25 mm (1.0 in.) space between
the FP-PS-4 and other devices on your DIN rail. After it is in
position, lock it to the DIN rail by pushing the rail clip to the
locked position, as shown in Figure 3.

Mounting Your FP-PS-4 on a Panel
Follow these steps to install the optional FieldPoint network panel
mount accessory and mount the FP-PS-4 power supply module to
a panel. You can order the panel mount accessory, part number
777609-01, from National Instruments.
1. Use a flat-bladed screwdriver to unlock the rail clip, as shown
in Figure 1.
2. Attach the panel mount accessory to the module, as shown in
Figure 4.

4. Mount the FP-PS-4 to your panel with the panel mount
accessory, as shown in Figure 5. The installation guide that
comes with the panel mount accessory includes a template that
you can use to drill pilot holes for mounting FieldPoint
modules. For maximum cooling, leave a 25 mm (1.0 in.) space
between the FP-PS-4 and other devices.

Caution
FieldPoint system, make sure the power cord is not
pluggedintoanelectricaloutlet.
Each FP-PS-4 provides a 24 VDC output. You decide the number
of FP-PS-4 modules you need in your bank based upon the specific
power and isolation requirements. The total power of all of the
FieldPoint modules and other devices connected to an FP-PS-4
cannot exceed the specified output for the temperature range at
which you are using FP-PS-4. For FieldPoint power requirement
details, refer to the operating instructions for your particular I/O
modules. Decide how you want to power your FieldPoint bank
based on the power requirements of your bank and your isolation
© National Instruments Corp. 5 FP-PS-4 Operating Instructions
Before you connect the FP-PS-4 to your
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.

Ensure that all the wiring is installed according to local codes and
regulations by qualified electrical personnel. Follow these steps to
connect the FP-PS-4 to your FieldPoint system.
1. Use a 16 to 26 AWG stranded wire to connect the FP-PS-4 to
your FieldPoint network module or I/O module. Connect the
positive wire to the V terminal and the negative wire to the
C terminal of the FP-PS-4.
2. Connect the other ends of the wires to the V and C terminals of
the FieldPoint network module or I/O module.
3. Ensure that the plug-in AC input terminal connector is plugged
into the input port on the FP-PS-4.
Be careful to install the correct conductor in the
Note
appropriate terminal. The color of the conductor wires
varies depending on North American versus international
standards as described in Figure 7. The wires are drawn
to scale according to the 7 mm (0.275 in.) strip length
requirement.

6. Connect the green or green/yellow conductor into the ground
terminal.
Caution
When you install the conductors, make sure that
the entire conductor is in the screw terminal and that there
are no loose strands outside of the terminal. Only install
one wire in each terminal.
