NI USB-6008/6009 Analog Input CircuitryThe main blocks featured in the NI USB-6008/6009 analog input circuitry are as follows:•MUX—The NI USB-6008/6009 has one analog-to-digital converter (ADC). The multiplexer (MUX) routes one AI channel at a time to the PGA.•PGA—The progammable-gain amplifier provides input gains of 1, 2, 4, 5, 8, 10, 16, or 20 when configured for differential measurements and gain of 1 when configured for single-endedmeasurements. The PGA gain is automatically calculated based on the voltage range selected in themeasurement application.•ADC—The analog-to-digital converter (ADC) digitizes the AI signal by converting the analog voltage into digital code.•AI FIFO—The NI USB-6008/6009 can perform both single and multiple analog-to-digital conversions of a fixed or infinite number of samples. A first-in-first-out (FIFO) buffer holds dataduring AI acquisitions to ensure that no data is lost.Analog Input Modes and Signal SourcesYou can configure the AI channels on the NI USB-6008/6009 to take differential or referencedsingle-ended (RSE) measurements. Table6 summarizes the recommended analog input mode(s) forfloating signal sources and ground-referenced signal sources. Refer to Table5 for more informationabout I/O connections for single-ended or differential measurements.Table 6. Analog Input ConfigurationsFloating Signal SourcesA floating signal source is not connected to the building ground system, but has an isolatedground-reference point. Some examples of floating signal sources are outputs of transformers, thermocouples, battery-powered devices, optical isolators, and isolation amplifiers. An instrument or device that has an isolated output is a floating signal source.Refer to the NI Developer Zone document, Field Wiring and Noise Considerations for Analog Signals, for more information. To access this document, go to /info and enter the Info Code rdfwn3. When to Use Differential Connections with Floating Signal SourcesUse DIFF input connections for any channel that meets any of the following conditions:•Your application requires input ranges other than ±10 V.•The input signal is low level and requires greater accuracy.•The leads connecting the signal to the device are greater than 3m (10ft).•The input signal requires a separate ground-reference point or return signal.•The signal leads travel through noisy environments.•Two analog input channels, AI+ and AI–, are available for the signal.DIFF signal connections reduce noise pickup and increase common-mode noise rejection. DIFF signal connections also allow input signals to float within the working voltage of the device.Refer to the Taking Differential Measurements section for more information about differential connections.When to Use Referenced Single-Ended (RSE) Connections with Floating Signal SourcesOnly use RSE input connections if the input signal meets all of the following conditions:•The input signal can share a common reference point, GND, with other signals that use RSE.•Your application permits the use of the ±10 V input range.•The leads connecting the signal to the device are less than 3m (10ft).DIFF input connections are recommended for greater signal integrity for any input signal that does not meet the preceding conditions.In the single-ended modes, more electrostatic and magnetic noise couples into the signal connections than in DIFF configurations. The coupling is the result of differences in the signal path. Magnetic coupling is proportional to the area between the two signal conductors. Electrical coupling is a function of how much the electric field differs between the two conductors.With this type of connection, the PGA rejects both the common-mode noise in the signal and the ground potential difference between the signal source and the device ground.Refer to the Taking Referenced Single-Ended Measurements section for more information about RSE connections.Ground-Referenced Signal SourcesA ground-referenced signal source is a signal source connected to the building system ground. It is already connected to a common ground point with respect to the device, assuming that the computer is plugged into the same power system as the source. Non-isolated outputs of instruments and devices that plug into the building power system fall into this category.The difference in ground potential between two instruments connected to the same building power system is typically between 1 and 100 mV, but the difference can be much higher if power distribution circuits are improperly connected. If a grounded signal source is incorrectly measured, this difference can appear as measurement error. Follow the connection instructions for grounded signal sources to eliminate this ground potential difference from the measured signal.Refer to the NI Developer Zone document, Field Wiring and Noise Considerations for Analog Signals, for more information. To access this document, go to /info and enter the Info Code rdfwn3. When to Use Differential Connections with Ground-Referenced Signal SourcesUse DIFF input connections for any channel that meets any of the following conditions:•Your application requires input ranges other than ±10 V.•The input signal is low level and requires greater accuracy.•The leads connecting the signal to the device are greater than 3m (10ft).•The input signal requires a separate ground-reference point or return signal.•The signal leads travel through noisy environments.•Two analog input channels, AI+ and AI–, are available for the signal.DIFF signal connections reduce noise pickup and increase common-mode noise rejection. DIFF signal connections also allow input signals to float within the working voltage of the device.Refer to the Taking Differential Measurements section for more information about differential connections.When to Use Referenced Single-Ended (RSE) Connections with Ground-Referenced Signal Sources Do not use RSE connections with ground-referenced signal sources. Use differential connections instead.As shown in the bottom-rightmost cell of Table6, there can be a potential difference between GND and the ground of the sensor. In RSE mode, this ground loop causes measurement errors.Taking Differential MeasurementsFor differential signals, connect the positive lead of the signal to the AI+terminal, and the negative lead to the AI– terminal.Figure 8. Connecting a Differential Voltage SignalThe differential input mode can measure ±20 V signals in the ±20V range. However, the maximum voltage on any one pin is ±10 V with respect to GND. For example, if AI 1 is +10 V and AI 5 is –10 V, then the measurement returned from the device is +20 V.Figure 9. Example of a Differential 20 V MeasurementConnecting a signal greater than ±10 V on either pin results in a clipped output.Figure 10. Exceeding ±10 V on AI Returns Clipped OutputTaking Referenced Single-Ended MeasurementsTo connect referenced single-ended (RSE) voltage signals to the NI USB-6008/6009, connect thepositive voltage signal to an AI terminal, and the ground signal to a GND terminal, as shown inFigure11.Figure 11. Connecting a Referenced Single-Ended Voltage SignalWhen no signals are connected to the analog input terminal, the internal resistor divider may cause the terminal to float to approximately 1.4 V when the analog input terminal is configured as RSE. Thisbehavior is normal and does not affect the measurement when a signal is connected.Digital TriggerYou can configure PFI0 as a digital trigger input for analog input tasks. Refer to the Using PFI0 as a Digital Trigger section for more information.Analog OutputThe NI USB-6008/6009 has two independent analog output channels that can generate outputs from 0 to 5 V. All updates of analog output channels are software-timed. GND is the ground-reference signal for the analog output channels.Figure12 shows the circuitry of one analog output channel on the NI USB-6008/6009.Figure 12. Circuitry of One Analog Output ChannelThe main block featured in the NI USB-6008/6009 analog output circuitry is the digital-to-analogconverter (DAC), which converts digital codes to analog voltages. There is one DAC for each analogoutput line.Connecting Analog Output LoadsTo connect loads to the NI USB-6008/6009, connect the positive lead of the load to the AO terminal,and connect the ground of the load to a GND terminal, as shown in Figure13.Figure 13. Connecting a LoadMinimizing Glitches on the Output SignalWhen you use a DAC to generate a waveform, you may observe glitches in the output signal. Theseglitches are normal; when a DAC switches from one voltage to another, it produces glitches due toreleased charges. The largest glitches occur when the most significant bit of the DAC code changes. You can build a lowpass deglitching filter to remove some of these glitches, depending on the frequency and nature of the output signal. For more information about minimizing glitches. refer to theKnowledgeBase document, Reducing Glitches on the Analog Output of MIO DAQ Devices.

Industrial Digital I/O Device for USB –60 V, Channel-to-Channel IsolatedOverview and ApplicationsThe National Instruments USB-6525 is a full-speed USB device with eight normally open, channel-to-channel isolated, solid-state relay outputs and eight ±60 VDC channel-to-channel isolated digital inputs. The NI USB-6525 offers features for industrial control and manufacturing test applications, such as factory automation, embedded machine control, and production line verification. The solid-state relay outputs have a 60 VDC/30 V rms switching voltage and 500 mA/ch maximum switching current, making them ideal for controlling pumps, valves, motors, and other industrial actuators. The eight isolated digital input channels break ground loops and offer protection from noise and spikes on external signals. You can also use one of the digital input channels as a 5 kHz, 32-bit event counter for counting digital pulses.HardwareThe USB-6525 has eight channel-to-channel optically isolated inputs,P1.<0..7>, and eight channel-to-channel optically isolated, solid-state relay outputs, P0.<0..7>. The isolated inputs consist of an optocoupler, a depletion-mode MOSFET-based current-limiting circuit, and a Schottky diode. Each channel has its own positive and negative terminals capable of detecting a wide range of DC signals, from 5 V TTL logic levels to DC power supply levels up to 60 V.PFI 0 (an alias to P1.7) can also function as the source for a 32-bit counter. In this mode, the device counts low to high transitions on P1.7. You can arm and disarm the counter as well as read or reset the count through software.You can connect loads to the solid-state relay outputs with an AC or DC power source. The default power-on state of the solid-state relays is open. The relays also remain open when the computer and the USB-6525device are powered off.•Small, portable digital I/O device •Eight channel-to-channel optically isolated inputs (±60 VDC)•Eight channel-to-channel optically isolated, solid-state relay outputs (60 VDC/30 V rms max)•500 mA maximum switching current per channel•One 32-bit event counter•Full-speed USB (12 Mb/s) bus interface •Built-in, removable connectors for easy connectivity•USB cable strain relief Operating Systems•Windows Vista/XP/2000Recommended Software •LabVIEW•LabWindows™/CVI •Measurement Studio •LabVIEW SignalExpressOther Compatible Software •Visual Studio .NET•C, C++•Visual BasicMeasurement Services Software (included)•NI-DAQmx driver software •Measurement & Automation Explorer configuration utility•LabVIEW SignalExpress LEdata-logging softwareNI USB-6525IsolationIsolation is a form of built-in signal conditioning that provides an extended voltage range for direct connectivity to industrial sensors and actuators. The USB-6525 provides channel-to-channel isolation where each channel is physically and electrically separated from the others. Isolation provides three main benefits:1.Safety from hazardous high voltages and transients2.Rejection of common-mode voltages3.Removal of ground loopsSafety from High-Voltage TransientsIsolation electrically separates high-voltage front-end channels from each other and the low-voltage back end of the USB-6525. Signalsare passed between the two sections of the device using optocouplers. By separating the two sections, any voltages within the isolation specifications are prevented from entering the USB bus section or other channels. Isolation provides protection for the user, data acquisition system, and measurement data.Common-Mode Voltage RejectionA voltage common to both sides of a differential circuit pair iscalled common-mode voltage. This phenomenon is typical in noisy environments containing machinery and inductive loads. The differential voltage across the circuit pair is the desired signal, whereas the common voltage signal is the unwanted signal that may have been coupled into the transmission line. The USB-6525 can measure signals from lines with signal plus common-mode voltage of up to 60 VDC.Ground Loop RemovalGround loops are the most common source of noise in data acquisition applications. They occur when two connected terminals in a circuit are at different ground potentials, causing current to flow between thetwo points. This additional voltage can cause significant error in the measurement. When a ground loop exists, the measured voltage isthe sum of the signal voltage and the potential difference that exists between the signal source ground and the measurement system ground. This potential is generally not a DC level; therefore, the result is a noisy measurement system. By offering an isolated floating ground on the front end, the isolated USB-6525 devices are able to prevent ground loops from forming.SoftwareNational Instruments measurement services software, built aroundNI-DAQmx driver software, includes intuitive application programming interfaces, configuration tools, I/O assistants, and other tools designed to reduce system setup, configuration, and development time.
