					NI USB-9472   
					8-Channel, 24 V Logic, Sourcing Digital Output Device   
					This user guide describes how to use the National Instruments   
					NI USB-9472 and lists the device specifications. In this user guide, the   
					NI USB-9472 with screw terminal and the NI USB-9472 with D-SUB are

					Introduction   
					The NI USB-9472 data acquisition device provides a USB interface for   
					eight channels of digital outputs with integrated signal conditioning. The   
					NI USB-9472 consists of two components: an NI 9472 module and an   
					NI USB-9162 carrier, as shown in Figure 1.

					Safety Guidelines   
					Operate the NI USB-9472 only as described in these operating instructions.   
					Note Although the NI 9472 module may have more stringent certification standards than   
					the NI USB-9472, when used with the NI USB-9162 carrier, the combined system may be   
					limited. Refer to the Specifications section for more details.   
					Hot Surface This icon denotes that the component may be hot. Touching this component   
					may result in bodily injury.   
					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 The NI USB-9472 is not certified for use in hazardous locations.   
					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 live with hazardous voltages, make sure that the   
					terminals are not accessible by using the high voltage screw terminal backshell. Refer to   
					the Connecting Devices to the NI USB-9472 section for more information.

					Connecting Devices to the NI USB-9472   
					The NI USB-9472 has current sourcing outputs, meaning the DO terminal   
					or pin drives current or applies voltage to the device to which it is   
					connected.   
					You can connect sinking-input devices, such as NPN, open collectors,   
					normally high, IEC negative logic, or other DC devices to the   
					NI USB-9472. A sinking-input device provides a path to ground for current   
					or voltage. Make sure the device you connect to the NI USB-9472 meets   
					the module specifications. Refer to the Specifications section for more   
					information about the output specifications of the module.   
					Connect the device to DO on the NI USB-9472. Connect the common of   
					the device to COM. Figure 8 shows a possible configuration.

					Assembling the High Voltage Screw Terminal Backshell   
					The NI 9932 high voltage screw terminal backshell must be installed when   
					using hazardous voltages (>42.4 Vpk, 60 VDC). Refer to Figure 9 while   
					completing the following steps to assemble the backshell:   
					1. Connect the leads to the screw terminal and secure with the strain   
					relief.   
					2. Finish by snapping the backshell around the connector.

					I/O Protection   
					The NI USB-9472 is short-circuit-proof in accordance with IEC 1131-2   
					and provides overcurrent protection.   
					Understanding Short-Circuit-Proof Devices   
					Each channel on the NI USB-9472 has circuitry that protects it from current   
					surges resulting from short circuits. Whether the module suffers damage   
					from these overcurrent conditions depends on the following factors:   
					• 
					• 
					• 
					The amount of current through the channel   
					The amount of time the current is above the current limit   
					The frequency of the current surges   
					When the amount of current through the DO terminal or pin is greater than   
					the guaranteed trip current for the module, the channel trips and goes into   
					an overcurrent state. In an overcurrent state, the channel turns off and the   
					module is not damaged. If the current through DO is higher than the   
					minimum possible trip current and lower than the guaranteed trip current,   
					the state of the channel is indeterminate and depends on factors such as the   
					current level, the temperature, and the power supply.   
					To prevent false tripping, higher inrush currents that exist for less than the   
					trip time do not trip the protection circuitry. Refer to the Specifications   
					section for more information about the maximum continuous output   
					current, trip current, and trip time. You also can refer to the IEC 1131-2   
					standard for more information about short-circuit-proof devices.   
					Tip Because the NI USB-9472 includes internal flyback diodes, you do not need to add   
					external diodes when connecting to switching energy storing devices.

					Power Supplies and Overcurrent Conditions   
					If a short-circuit occurs, the current through DO can exceed the current   
					rating for the power supply and the maximum continuous output current for   
					the NI USB-9472.   
					If the power supply you are using with the NI USB-9472 cannot supply   
					more than the guaranteed trip current, the module may be damaged if a   
					short-circuit condition occurs.   
					Detecting an Overcurrent Condition   
					If a device connected to the module is not working while the channel is on,   
					the module channel may be in an overcurrent state. Neither the software nor   
					the module LEDs indicate if an overcurrent condition occurs. A channel   
					LED may be on even though the channel is off because of an overcurrent   
					condition. To determine if the channel is in an overcurrent state, measure   
					the voltage between DO and Vsup. If the voltage is equal to the voltage of   
					the external power supply connected to the module, the channel is in an   
					overcurrent state.   
					Resetting Channels After an Overcurrent Condition   
					After you have determined and fixed the cause of the overcurrent condition,   
					reset the channel by turning it off. You can disconnect the external power   
					supply from the module, however, doing so disconnects power from all of   
					the module channels. Normal operation can resume after you correct the   
					overcurrent condition and reset the channel.
