Safety Guidelines for Hazardous Voltages  
If hazardous voltages are connected to the module, take the  
following precautions. A hazardous voltage is a voltage greater  
than 42.4 Vpk or 60 VDC to earth ground.  
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 module terminals are hazardous voltage  
LIVE (>42.4 Vpk/60 VDC), you must ensure that devices  
and circuits connected to the module are properly  
insulated from human contact.  
Safety Guidelines for Hazardous Locations  
The NI 9426 is suitable for use in Class I, Division 2, Groups A, B,  
C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4, and

NI 9426 Operating Instructions and Specifications  
 
Ex nA IIC T4 hazardous locations; and nonhazardous locations  
only. Follow these guidelines if you are installing the NI 9426 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.  
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, install a protection  
device that prevents the Vsup voltage from exceeding  
42 V if there is a transient overvoltage condition.

Special Conditions for Hazardous Locations Use in Europe  
This equipment has been evaluated as Ex nA IIC T4 equipment  
under DEMKO Certificate No. 07 ATEX 0626664X. Each module  
is marked  
II 3G and is suitable for use in Zone 2 hazardous  
locations. If you are using the NI 9426 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.

Each channel has a DI pin to which you can connect a digital input  
signal. The NI 9426 has four supply pins, Vsup, that are internally  
connected to the isolated reference of the module.  
The NI 9426 has sourcing inputs, meaning the DI pin sources  
current from Vsup to the sinking output device. The NI 9426  
internally limits current signals connected to DI. For more  
information about input current levels, refer to the Specifications  
section.  
You can connect 2-, 3-, and 4-wire sinking-output devices to  
the NI 9426. A sinking-output device provides a path from the  
DI pin to a voltage below Vsup. An example of a sinking-output  
device is an open collector NPN.  
Connect the sinking-output device to the DI pin of the NI 9426.  
Connect the positive power supply lead of the external device to the  
Vsup pin. Refer to Figure 2 for an illustration of connecting a device  
to the NI 9426.

The NI 9426 channel registers as ON when the sinking-output  
device drives the input below Vsup and meets the input ON range.  
The channel registers as OFF when the device does not drive the  
input low and is in the input OFF range. If no device is connected  
to the DI pin, the channel registers as OFF. Refer to the  
Specifications section for more information about the ON and  
OFF states.

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.

The following specifications are typical for the range –40 to 70 °C  
unless otherwise noted. All voltages are relative to Vsup unless
