Safety Guidelines  
Operate the NI 9401 only as described in these operating  
instructions.  
Hot Surface This icon denotes that the component may be  
hot. Touching this component may result in bodily injury.  
Safety Guidelines for Hazardous Locations  
The NI 9401 is suitable for use in Class I, Division 2, Groups A, B,

only. Follow these guidelines if you are installing the NI 9401 in a  
potentially explosive environment. Not following 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.

NI 9401 Operating Instructions and Specifications  
 
Caution Substitution of components may impair  
suitability for Class I, Division 2.  
Caution For Zone 2 applications, install the system  
in an enclosure rated to at least IP 54 as defined by  
IEC 60529 and EN 60529.  
Caution For Zone 2 applications, connected signals must  
be within the following limit:  
Capacitance..........................0.2 μF max  
Special Conditions for Hazardous Locations Use in Europe  
This equipment has been evaluated as EEx nC IIC T4 equipment  
under DEMKO Certificate No. 03 ATEX 0324020X. Each module  
is marked  
II 3G and is suitable for use in Zone 2 hazardous  
locations. If you are using the NI 9401 in Gas Group IIC hazardous  
locations or in ambient temperatures of –40 °C Ta 70 °C, you  
must use the device in an NI chassis that has been evaluated as  
EEx nC IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.

Special Conditions for Marine Applications  
Some modules are Lloyd’s Register (LR) Type Approved for  
marine applications. To verify Lloyd’s Register certification, visit  
ni.com/certification and search for the LR certificate, or  
look for the Lloyd’s Register mark on the module.  
Caution To meet radio frequency emission requirements  
for marine applications, use shielded cables and install  
the system in a metal enclosure. Suppression ferrites  
must be installed on power supply inputs near power  
entries to modules and controllers. Power supply and  
module cables must be separated on opposite sides of the  
enclosure and must enter and exit through opposing  
enclosure walls.

Connecting the NI 9401  
The NI 9401 has a 25-pin DSUB connector that provides  
connections for eight digital input/output channels.

Each channel has a DIO pin to which you can connect a digital  
input or output device. The eight DIO channels are internally  
referenced to COM, so you can use any of the nine COM lines as  
a reference for the external signal.  
The DIO channels are grouped in two ports, one containing  
channels 0, 1, 2, and 3, and one containing channels 4, 5, 6, and 7.  
You can independently configure each digital port in software for  
input or output. Note that all four channels in the port must share  
the same line direction. Refer to the software help for information  
about configuring ports on the NI 9401.  
Each channel also has a pull-down resistor and includes  
overvoltage, overcurrent, and short-circuit protection. Refer to the  
Specifications section for more information about input thresholds  
and overvoltage protection. Refer to the Overcurrent Protection  
section for more information about overcurrent protection.

NI 9401 Operating Instructions and Specifications  
 
 
Overcurrent Protection  
Overcurrent protection on the NI 9401 allows only a specified  
amount of current for switching DIO channels or sourcing the  
output load. If the NI 9401 goes into an overcurrent state, by  
exceeding the specified maximum switching frequency or the  
output load, the module power supply begins to drop in voltage  
until it completely turns off or the overcurrent condition is  
removed. When the module is in this state, it can accept new line  
direction configuration and output state data but cannot pass valid  
input data to the software. Refer to the Specifications section for  
more information about the maximum switching frequency and  
output load for each channel.

Sleep Mode  
This module supports a low-power sleep mode. Support for sleep  
mode at the system level depends on the chassis that the module is  
plugged into. Refer to the chassis manual for information about  
support for sleep mode. If the chassis supports sleep mode, refer to  
the software help for information about enabling sleep mode. Visit  
ni.com/info and enter cseriesdoc for information about  
C Series documentation.  
Typically, when a system is in sleep mode, you cannot  
communicate with the modules. In sleep mode, the system  
consumes minimal power and may dissipate less heat than it does  
in normal mode. Refer to the Specifications section for more  
information about power consumption and thermal dissipation.
