(overvoltage) from the circuit to which they are connected during measurement or test. Measurement categories establish standard impulse withstand voltage levels that commonly occur in electrical distribution systems. The following is a description of measurement categories:

• Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS

voltage. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

Measurement Category as defined in electrical safety standard IEC 61010-1. Measurement Category is also referred to as Installation Category.

Working Voltage is the highest rms value of an AC or DC voltage that can occur across any particular insulation.

MAINS is defined as a hazardous live electrical supply system that powers equipment. Suitably rated measuring circuits may be connected to the MAINS for measuring purposes.

NI USB-6008/6009 User Guide and Specifications 4 ni.com

• Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level electrical distribution, such as that provided by a standard wall outlet (for example, 115 V for U.S. or 230 V for Europe). Examples of Measurement Category II are measurements performed on household appliances, portable tools, and similar E Series devices.

• Measurement Category III is for measurements performed in the building installation at the distribution level. This category refers to measurements on hard-wired equipment such as equipment in fixed installations, distribution boards, and circuit breakers. Other examples are wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and stationary motors with permanent connections to fixed installations.

• Measurement Category IV is for measurements performed at the primary electrical supply installation (<1,000 V). Examples include electricity meters and measurements on primary overcurrent protection devices and on ripple control units.

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-ended measurements. The PGA gain is automatically calculated based on the voltage range selected in the measurement application.

A/D Converter

The analog-to-digital converter (ADC) digitizes the AI signal by converting the analog voltage into a digital code.

Analog Input Modes

AI FIFO

The NI USB-6008/6009 can perform both single and multiple A/D conversions of a fixed or infinite number of samples. A first-in-first-out (FIFO) buffer holds data during AI acquisitions to ensure that no data is lost.

You can configure the AI channels on the NI USB-6008/6009 to take single-ended or differential measurements. Refer to Table 6 for more information about I/O connections for single-ended or differential measurements.

Connecting Differential Voltage Signals

For differential signals, connect the positive lead of the signal to the AI+ terminal, and the negative lead to the AI– terminal.

Connecting Reference Single-Ended Voltage Signals

To connect reference single-ended voltage signals (RSE) to the NI USB-6008/6009, connect the positive voltage signal to the desired AI terminal, and the ground signal to a GND terminal, as illustrated in Figure 11.

When 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. This behavior is normal and does not affect the measurement when a signal is connected.

Digital Trigger

When an AI task is defined, you can configure PFI 0 as a digital trigger input. When the digital trigger is enabled, the AI task waits for a rising or falling edge on PFI 0 before starting the acquisition. To use ai/Start Trigger with a digital source, specify PFI 0 as the source and select rising or falling edge.

Analog Output

The NI USB-6008/6009 has two independent AO channels that can generate outputs from 0–5 V. All updates of AO lines are software-timed.

Minimizing Glitches on the Output Signal

When you use a DAC to generate a waveform, you may observe glitches in the output signal. These glitches are normal; when a DAQ switches from one voltage to another, it produces glitches due to released 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. Refer to glitches.

Digital I/O

The NI USB-6008/6009 has 12 digital lines, P0.<0..7> and P1.<0..3>, which comprise the DIO port. GND is the ground-reference signal for the DIO port. You can individually program all lines as inputs or outputs.

Exceeding the maximum input voltage ratings or maximum output ratings, which are listed in the Specifications section, can damage the device and the computer. National Instruments is not liable for any damage resulting from such signal connections.

Source/Sink Information

The default configuration of the NI USB-6008/6009 DIO ports is open collector, allowing 5 V operation, with an onboard 4.7 kΩ pull-up resistor. An external user-provided pull-up resistor can be added to increase the source current drive up to a 8.5 mA limit per line as shown in Figure 15.

The NI USB-6009 ports can also be configured as active drive using the NI-DAQmx API, allowing 3.3 V operation with a source/sink current limit of ±8.5 mA. Refer to the NI-DAQmx Help for more information about how to set the DIO configuration.

Complete the following steps to determine the value of the user-provided pull-up resistor:

1. Place an ammeter in series with the load.

2. Place a variable resistor between the digital output line and the +5 V.

3. Adjust the variable resistor until the ammeter current reads as the intended current. The intended current must be less than 8.5 mA.

4. Remove the ammeter and variable resistor from your circuit.

5. Measure the resistance of the variable resistor. The measured resistance is the ideal value of the pull-up resistor.

6. Select a static resistor value for your pull-up resistor that is greater than or equal to the ideal resistance.

7. Re-connect the load circuit and the pull-up resistor.

I/O Protection

Power-On States

To protect the NI USB-6008/6009 against overvoltage, undervoltage, and overcurrent conditions, as well as ESD events, you should avoid these fault conditions by using the following guidelines:

• If you configure a DIO line as an output, do not connect it to any external signal source, ground signal, or power supply.

• If you configure a DIO line as an output, understand the current requirements of the load connected to these signals. Do not exceed the specified current output limits of the DAQ device.

National Instruments has several signal conditioning solutions for digital applications requiring high current drive.

• If you configure a DIO line as an input, do not drive the line with voltages outside of its normal operating range. The DIO lines have a smaller operating range than the AI signals.

• Treat the DAQ device as you would treat any static sensitive device. Always properly ground yourself and the equipment when handling the DAQ device or connecting to it.

At system startup and reset, the hardware sets all DIO lines to high-impedance inputs. The DAQ device does not drive the signal high or low. Each line has a weak pull-up resistor connected to it.

Static DIO

Each of the NI USB-6008/6009 DIO lines can be used as a static DI or DO line. You can use static DIO lines to monitor or control digital signals. All samples of static DI lines and updates of DO lines are software-timed.

Event Counter

You can configure PFI 0 as a source for a gated invertor counter input edge count task. In this mode, falling-edge events are counted using a 32-bit counter. For more information about event timing requirements, refer to the

Specifications section.
