Figure 3 shows how to connect a sourcing-output device to one
channel of the cFP-DI-304.
Figure 3. Sourcing-Output Device Connected to One Channel
Note You must ground all connected devices to the
C terminals.
Digital Input Circuitry
The cFP-DI-304 has 32 input channels. You can connect a voltage
signal to each channel. All 32 input channels share a common
ground reference that is isolated from other modules in the
FieldPoint system.
When you apply a voltage above 10 V to a VIN terminal, current
flows through that terminal and the channel is ON. When you
apply a voltage below 5 V to a VIN terminal, the channel is OFF.
When you apply a voltage between 5 and 10 V, the channel may be
ON or OFF.
The cFP-DI-304 has sinking inputs, which means that current
flows through the VIN terminal to the input circuitry. The inputs are
compatible with sourcing-output devices capable of sourcing
or driving current from a positive supply voltage to common.
A sensor is an example of a sourcing-output device.
Make sure that devices you connect to the cFP-DI-304 have OFF
state leakage currents of less than 150 µA to ensure that they do not
provide false ON state readings to the cFP-DI-304.

Status Indicators
The cFP-DI-304 has two green status LEDs, POWER and
READY. After you insert the cFP-DI-304 into a backplane and
apply power to the connected network module, the green POWER
indicator lights and the cFP-DI-304 informs the network module
of its presence. When the network module recognizes the
cFP-DI-304, it sends initial configuration information to the
cFP-DI-304. After the cFP-DI-304 receives this initial information,
the green READY indicator lights and the module is in normal
operating mode.
In addition to the POWER and READY lights, each channel has a
numbered green status indicator that lights when the channel is in
the ON state.
Upgrading the FieldPoint Software
In order to use the cFP-DI-304, you must have FieldPoint software
version 5.0 or later installed on the host computer. Go to
ni.com/support, select Drivers and Updates»Current
Versions»Distributed I/O—FieldPoint, and select the latest
version under Driver.
Upgrading the FieldPoint Firmware
You may need to upgrade the FieldPoint firmware when you add
new I/O modules to the FieldPoint system. For information about
determining which firmware you need and how to upgrade your
firmware, go to ni.com/info and enter fpmatrix.

Isolation and Safety Guidelines
Caution Read the following information before
attempting to connect the cFP-DI-304 to any circuits
that may contain hazardous voltages.1
This section describes the isolation of the cFP-DI-304 and
its compliance with international safety standards. The field
wiring connections are isolated from the backplane and the
inter-module communication bus. The isolation barriers in the
module provide 250 Vrms Measurement Category II continuous
channel-to-backplane and channel-to-ground isolation, verified
by a 2,300 Vrms , 5 s dielectric withstand test.2The cFP-DI-304
provides double insulation compliant with IEC 61010-1 for
working voltages of 250 Vrms.3Safety standards (such as those
published by UL and IEC) require the use of double insulation
between hazardous voltages and any human-accessible parts or
circuits.
Never try to use any isolation product between human-accessible
parts (such as DIN rails or monitoring stations) and circuits that
can be at hazardous potentials under normal conditions, unless the
product is specifically designed for such an application, as is the
cFP-DI-304.
Even though the cFP-DI-304 is designed to handle applications
with hazardous potentials, follow these guidelines to ensure a safe
total system:
•There is no isolation between channels on the cFP-DI-304. If a
hazardous voltage is present on any channel, all channels are
considered hazardous. Make sure that all other devices and
circuits connected to the module are properly insulated from
human contact.
•Do not share the external supply voltages (the V and
C terminals) with other devices, including other FieldPoint
devices, unless those devices are isolated from human contact.
1 A hazardous voltage is a voltage greater than 42.4 Vpeak or 60 VDC. When a
hazardous voltage is present on any channel, all of the channels must be considered
to be carrying hazardous voltages. Ensure that all circuits connected to the module
are inaccessible to human touch.
2 Refer to the Safety Isolation Voltage section for more information about isolation on
the cFP-DI-304.
3 Working voltage is defined as the signal voltage plus the common-mode voltage.
Common-mode voltage is the voltage of the module with respect to ground.

•For Compact FieldPoint, you must connect the protective earth
(PE) ground terminal on the cFP-BP-xbackplane to the system
safety ground. The backplane PE ground terminal has the
following symbol stamped beside it: . Connect the
backplane PE ground terminal to the system safety ground
using 14 AWG (1.6 mm) wire with a ring lug. Use the 5/16 in.
panhead screw shipped with the backplane to secure the ring
lug to the backplane PE ground terminal.
•As with any hazardous voltage wiring, make sure that all
wiring and connections meet applicable electrical codes and
commonsense practices. Mount terminal bases and backplanes
in an area, position, or cabinet that prevents accidental or
unauthorized access to wiring that carries hazardous voltages.
•Do not use the cFP-DI-304 as the only isolating barrier
between human contact and working voltages higher than
250 Vrms .
•Operate the cFP-DI-304 only at or below Pollution Degree 2.
Pollution Degree 2 means that only nonconductive pollution
occurs in most cases. Occasionally, however, temporary
conductivity caused by condensation must be expected.
•Operate the cFP-DI-304 at or below Measurement Category II.
Measurement Category II is for measurements performed on
circuits directly connected to the low-voltage installation.
This category refers to local-level distribution, such as that
provided by a standard wall outlet.
Safety Guidelines for Hazardous Locations
The cFP-DI-304 is suitable for use in Class I, Division 2, Groups
A, B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nC IIC
T4 and Ex nC IIC T4 hazardous locations; and nonhazardous
locations only. Follow these guidelines if you are installing the
cFP-DI-304 in a potentially explosive environment. Failing to
follow these guidelines may result in serious injury or death.
Caution Do not disconnect I/O-side wires or connectors
unless power has been switched off or the area is known
to be nonhazardous.
Caution Do not remove modules unless power has been
switched off or the area is known to be nonhazardous.

locations.
Safety Guidelines for Hazardous Voltages
If hazardous voltages are connected to the module, take the
following precautions:
Caution Ensure that hazardous voltage wiring is
performed only by qualified personnel adhering to local
electrical standards.
Caution Do not mix hazardous voltage circuits and
human-accessible circuits on the same module.
Caution Make sure that devices and circuits connected to
the module are properly insulated from human contact.
Caution When terminals on the connector block are live
with hazardous voltages, make sure that the terminals are
