II 3G 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 9206 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.
Furthermore, any changes or modifications to the product not expressly approved by National Instruments could void your authority to operate it under your local regulatory rules. 10 | ni.com | NI 9206 Getting Started Guide...
Preparing the Environment Ensure that the environment in which you are using the NI 9206 meets the following specifications. Operating temperature -40 °C to 70 °C (IEC 60068-2-1, IEC 60068-2-2) Operating humidity 10% RH to 90% RH, (IEC 60068-2-78) noncondensing...

Signals You can connect single-ended or differential signals to the NI 9206. Use a differential measurement configuration to attain more accurate measurements and less noise. The following table shows the signal pairs that are valid for differential connection configurations with the NI 9206.
– AI9 (CH1–) NI 9206 To connect floating differential signals to the NI 9206, you must connect the negative signal to COM through a 1 MΩ resistor to keep the voltage within the maximum working voltage. If the voltage source is outside the maximum working voltage, the NI 9206 does not read data accurately.
Connecting Grounded Differential Signals You can connect grounded differential signals to the NI 9206. Figure 3. Connecting Grounded Differential Signals to the NI 9206 AI0 (CH0+) – AI8 (CH0–) PGIA AI1 (CH1+) – AI9 (CH1–) NI 9206 In a differential configuration, the NI 9206 rejects the common- mode noise voltage during the measurement of V .
NI 9206 In an RSE configuration, the NI 9206 measures each channel with respect to COM. To connect RSE signals to the NI 9206, you must connect the voltage ground signal to COM to keep the maximum working voltage in the specified range.
10 V of COM. Connecting NRSE Voltage Signals You can connect non-referenced single-ended (NRSE) signals to the NI 9206. Figure 5. Connecting an RSE Voltage Signal to the NI 9206 – PGIA – AISENSE...
RSE connection. Connecting Fuel Cell Devices You can connect a fuel cell device to the NI 9206. Figure 6. Connecting a Fuel Cell Device to the NI 9206 AI23+ Cell n + 15 –...
NI 9206 Connection Guidelines • Make sure that devices you connect to the NI 9206 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 9206.
High-Vibration Application Connections If your application is subject to high vibration, NI recommends that you use the NI 9941 backshell kit to protect connections to the NI 9206. 24 | ni.com | NI 9206 Getting Started Guide...
