intended hazardous (classified) location, having a tool secured cover/door,
where a minimum protection of at least IP54 is provided.
Special Conditions for Hazardous Locations Use in Europe and
Internationally
The NI-9207 with spring terminal has been evaluated as equipment under DEMKO
ATEX and is IECEx certified. The NI-9207 with DSUB has been evaluated as
equipment under DEMKO ATEX and is IECEx certified. Each NI-9207 is marked and is
suitable for use in Zone 2 hazardous locations, in ambient temperatures of -40 °C ≤
Ta ≤ 70 °C. If you are using the NI-9207 in Gas Group IIC hazardous locations, you
must use the device in an NI chassis that has been evaluated as Ex nC IIC T4, Ex IIC
T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.
Caution Transient protection shall be provided that is set at a level not
exceeding 140% of the peak rated voltage value of 85 V at the supply
terminals to the equipment.
Caution The system shall only be used in an area of not more than
Pollution Degree 2, as defined in IEC/EN 60664-1.
Caution The system shall be mounted in an ATEX/IECEx-certified
enclosure with a minimum ingress protection rating of at least IP54 as
defined in IEC/EN 60079-15.
Caution The enclosure must have a door or cover accessible only by the
use of a tool.

by National Instruments could void your authority to operate it under your local
regulatory rules.
Special Conditions for Marine Applications
Some products are approved for marine (shipboard) applications. To verify marine
approval certification for a product, visit ni.com/product-certifications, search by
model number, and click the appropriate link.
Notice In order to meet the EMC requirements for marine applications,
install the product in a shielded enclosure with shielded and/or filtered
power and input/output ports. In addition, take precautions when
designing, selecting, and installing measurement probes and cables to
ensure that the desired EMC performance is attained.
Preparing the Environment
Ensure that the environment in which you are using the NI-9207 meets the following
specifications.
Operating temperature (IEC 60068-2-1, IEC 60068-2-2) -40 °C to 70 °C

Connecting an External Power Supply
You must connect an external power supply with a 0 to 30 V voltage range to the
NI-9207. This power supply provides the current for the devices you connect to the
module. You can connect only one external voltage supply to the NI-9207.
1. Connect the positive lead of the power supply to Vsup.
2. Connect the negative lead of the power supply to COM.

NI-9207 Connection Guidelines
■ Make sure that devices you connect to the NI-9207 are compatible with the
module specifications.
■ You must use 2-wire ferrules to create a secure connection when connecting
more than one wire to a single terminal on the NI-9207 with spring terminal.
■ Push the wire into the terminal when using a solid wire or a stranded wire
with a ferrule.

■ Open the terminal by pressing the push button when using stranded wire
without a ferrule.
High-Vibration Application Connections
If your application is subject to high vibration, NI recommends that you use the
NI-9940 backshell kit to protect connections to the NI-9207 with spring terminal.
Overvoltage Protection
The NI-9207 provides overvoltage protection for each channel.
Note Refer to the NI-9207 Specifications on ni.com/manuals for more
information about overvoltage protection.
