Wiring the [c]FP-DO-403  
The FP-TB-x terminal base has connections for each FP-DO-403  
output channel and for an external supply to power field devices.  
The cFP-CB-x connector block provides the same connections for  
the cFP-DO-403.  
Each channel has one output terminal, VOUT. The output channels  
share eight VSUP terminals and eight COM terminals. All of the  
channels are referenced to the COM terminals. The V and VSUP  
terminals are all internally connected, as are the C and COM  
terminals.  
Use a 5–30 VDC external power supply for the output channels.  
The power supply must provide enough current to power all of the

loads on the output channels, up to 2 A per channel.1 Connect  
the external power supply to multiple V and VSUP terminals and  
to multiple C and COM terminals as needed to ensure that the  
maximum current through any terminal is 2 A or less.  
Install a 2 A maximum, fast-acting fuse (F2A 250V) between the  
external power supply and the VSUP terminal on each channel.  
Install a 2 A maximum, fast-acting fuse suitable for the load at the  
VOUT terminal. Figure 3 shows fuses where appropriate.  
Table 1 lists the terminal assignments for the signals associated  
with each channel. Terminal assignments and wiring diagrams are  
also listed on the side panel of the cFP-DO-403 and under the  
slide-in card on the front of the FP-DO-403 module.

[c]FP-DO-403  
 
   
Digital Output Circuit  
The [c]FP-DO-403 digital output channels are optically isolated  
from the rest of the FieldPoint bank. In the ON state, a transistor is  
turned on between the VOUT terminal and the external supply (the  
C and COM terminals). In the OFF state, this transistor is turned  
off, allowing only a small leakage current to flow. The VOUT  
terminal sinks current from external devices. Sinking current  
means the VOUT terminal provides a path to the supply common.  
Ensure that no channel sinks more than 2 A, and that the total  
current supplied by all channels at any time is no more than 16 A2.  
To determine whether the total current is within the limit, square  
the current on each channel and add the squares together. If the sum  
of all the squares is less than or equal to 16 A2, the total current is  
within the limit. In the following example, three channels sink 2 A  
and four channels sink 1 A each:  
(2 A)2 + (2 A)2 + (2 A)2 + (1 A)2  
+ (1 A)2 + (1 A)2 + (1 A)2 16 A2  
Caution The outputs must not be short-circuited to the  
potential of the V or VSUP terminals (the positive voltage  
of the external supply). Short circuits damage the  
[c]FP-DO-403 output channels. Check all wiring  
carefully before applying power.  
In the ON state, there is an effective resistance of 0.12 Ω between  
the output (VOUT) and the supply voltage (the C and COM  
terminals). This resistance causes a voltage drop between the  
external supply voltage and the output voltage. For example,  
if the external supply voltage is 5 V and the output current is 1 A,  
the output voltage is 4.88 V:  
5 V – 1 A × 0.12 Ω = 4.88 V  
Protection for Inductive Loads  
When an inductive load, such as a motor or relay, is connected to  
an output, a large counter-electromotive force may occur at  
switching time because of the energy stored in the inductive load.  
This flyback voltage can damage the outputs and the power supply.  
It is best to limit such flyback voltages at the inductive load by  
installing a flyback diode across the load. Typically, you should  
[c]FP-DO-403

mount the flyback diode within 18 in. of the load. Figure 5 shows  
a flyback diode connected to an inductive load.

Figure 5. Connection to Inductive Load with Flyback Diode  
Although the [c]FP-DO-403 contains flyback diodes to prevent  
excessively high voltage from damaging the module, National  
Instruments recommends the use of an external protection circuit  
across any inductive load.  
Status Indicators  
The [c]FP-DO-403 has two green status LEDs, POWER and  
READY. After you insert the FP-DO-403 into a terminal base  
or the cFP-DO-403 into a backplane and apply power to the  
connected network module, the green POWER indicator lights  
and the [c]FP-DO-403 informs the network module of its presence.  
When the network module recognizes the [c]FP-DO-403, it sends  
initial configuration information to the [c]FP-DO-403. After the  
module receives this initial information, the green READY  
indicator lights and the [c]FP-DO-403 is in normal operating  
mode.  
In addition to the green POWER and READY indicators, each  
channel has a numbered, green output state indicator, which lights  
when the channel is in the ON state.  
Isolation and Safety Guidelines  
Caution Read the following information before  
attempting to connect the [c]FP-DO-403 to any circuits  
that may contain hazardous voltages.  
This section describes the isolation of the [c]FP-DO-403 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

[c]FP-DO-403  
 
 
250 Vrms Measurement Category II continuous isolation, verified  
by 2,300 Vrms, 5 s dielectric withstand test. The [c]FP-DO-403  
provides double insulation (compliant with IEC 61010-1) for  
working voltages of 250 Vrms1. Safety 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  
[c]FP-DO-403.  
Even though the [c]FP-DO-403 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 [c]FP-DO-403.  
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.  
For Compact FieldPoint, you must connect the protective earth  
(PE) ground terminal on the cFP-BP-x backplane 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.

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.

Do not use the [c]FP-DO-403 as the only isolating barrier  
between human contact and working voltages higher than  
250 Vrms  
.
Operate the [c]FP-DO-403 only at or below Pollution  
Degree 2. Pollution Degree 2 means that only nonconductive  
pollution occurs in most cases. Occasionally, however, a  
temporary conductivity caused by condensation must be  
expected.  
Operate the [c]FP-DO-403 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.
