Safety Guidelines Operate the NI 9201/9221 only as described in these operating instructions. This icon denotes that the component may be hot. Touching this component may result in bodily injury. Hot Surface Safety Guidelines for Hazardous Voltages You can connect hazardous voltages only to the NI 9201/9221 with screw terminal. Do not connect hazardous voltages to the NI 9201/9221 with DSUB. If hazardous voltages are connected to the module, take the following precautions.
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. You must use the NI 9932 connector backshell kit to ensure that the terminals are not accessible. Caution Figure 1 shows the NI 9932 connector backshell.
Figure 1. NI 9932 Connector Backshell Safety Guidelines for Hazardous Locations The NI 9201/9221 is suitable for use in Class I, Division 2, Groups A, B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nC IIC T4, and Ex nC IIC T4 hazardous locations; and nonhazardous locations only. Follow these guidelines if you are installing the NI 9201/9221 in a potentially explosive environment. Not following these guidelines may result in serious injury or death. © National Instruments Corp.
Caution Do not disconnect I/O-side wires or connectors unless power has been switched off or the area is known to be nonhazardous. 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.
locations. If you are using the NI 9201/9221 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.

The NI 9201/9221 with screw terminal has a 10-terminal, detachable screw-terminal connector. The NI 9201/9221 with DSUB has a 25-pin DSUB connector. Each channel has an AI terminal or pin to which you can connect a voltage signal. COM, the common terminal or pin, is internally connected to the isolated ground reference of the module. The NI 9201/9221 channels are isolated from other modules in the system. The module protects each channel from overvoltages.
You can connect single-ended voltage signals to the NI 9201/9221. Connect the positive lead of the voltage signal to AI. Connect the ground signal to COM. Refer to Figure 3 for an illustration of connecting a single-ended voltage signal to the NI 9201/9221. AI Voltage Source + – COM NI 9201/9221 Figure 4.

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.
