Caution When module terminals are hazardous voltage LIVE (>42.4 V_pk/60 VDC), you

must ensure that devices and circuits connected to the module are properly insulated from

human contact. You must use the NI 9972 connector backshell kit, as illustrated in Figure 3

to ensure that the terminals are not accessible.

LED Indicator

The NI USB-9219 device has a green LED next to the USB connector. The

LED indicator indicates device status, as listed in Table 1. When the device

is connected to a USB port, the LED blinks steadily to indicate that the

device is initialized and is receiving power from the connection.

If the LED is not blinking, it may mean that the device is not initialized or

the computer is in standby mode. In order for the device to be recognized,

the device must be connected to a computer that has NI-DAQmx installed

on it. If your device is not blinking, make sure your computer has the latest

version of NI-DAQmx installed on it, and the computer is not in standby

mode.

Connecting Wires to the NI USB-9219 Connectors

Use a flathead screwdriver with a blade smaller than 2.3 × 1.0 mm (0.09 ×

0.04 in.) to connect wires to the detachable spring-terminal connectors.

Insert the screwdriver into a spring clamp activation slot and press a wire

into the corresponding connector terminal, then remove the screwdriver to

clamp the wire into the terminal. Refer to the Specifications section for

more information about spring-terminal wiring. Refer to Figure 7 for an

illustration of connecting wires to the NI USB-9219.

Figure 7. Connecting Wires to the NI USB-9219 Connectors

NI USB-9219 User Guide and Specifications

Wiring TEDS Channels

The NI USB-9219 supports only Class II TEDS sensors. Connect the two

TEDS lines to TEDS Data (T+) and TEDS COM (T–) and ensure that

neither T+ nor T– is tied in common to any of the signal inputs (terminals

3 through 6) on the NI USB-9219. Visit ni.com/info and enter the info

code rdteds for information about TEDS sensors.

Grounding and Shielding Considerations

You can connect ground-referenced or floating signal sources to the

NI USB-9219. If you make a floating connection between the signal source

and the NI USB-9219, make sure the voltages on the positive and negative

connections are within the channel-to-earth working voltage range to

ensure proper operation of the NI USB-9219. Refer to the Specifications

section for more inform ation about operating voltages and overvoltage

protection.

Note For best signal quality, National Instruments recommends using shielded cables and

twisted-pair wiring whenever possible.

NI USB-9219 Timing Options

The NI USB-9219 supports four different timing options that are optimized

for different types of applications by using different ADC conversion

times. High Speed is optimized for high speed at the expense of noise

rejection, Best 60 Hz Rejection is optimized for rejection of 60 Hz noise,

Best 50 Hz Rejection is optimized for rejection of 50 Hz noise, and High

Resolution is optimized for maximum overall noise rejection and provides

good rejection of 50 Hz and 60 Hz noise. Refer to the Specifications section

for more information.

NI USB-9219 Circuitry

The NI USB-9219 is channel-to-channel isolated. Four 24-bit

analog-to-digital converters (ADCs) simultaneously sample all four analog

input channels. An excitation circuit is enabled for all input modes that

require excitation. The ADC and excitation circuits are reconfigured in

each mode to accommodate each type of sensor. Refer to Figure 10 for an

illustration of the input circuitry for one channel of the NI USB-9219.

Voltage and Current Modes

In Voltage and Current modes, connect the signal source to the

NI USB-9219 across the HI and LO terminals. The current is computed

from the voltage that the ADC measures across an internal shunt resistor.

Refer to Figure 11 for an illustration of the connections.

4-Wire Resistance and 4-Wire RTD Modes

4-Wire Resistance and 4-Wire RTD modes source a current, which varies

based on the resistance of the load, between the EX+ and EX– terminals.

The measured resistance is computed from the resulting voltage reading.

These modes are not affected by lead wire resistance because a negligible

amount of current flows across the HI and LO terminals due to the high

input impedance of the ADC. Refer to Figure 12 for an illustration of the

connections.

3-Wire RTD Mode

3-Wire RTD mode sources a current, which varies based on the resistance

of the load, between the EX+ and EX– terminals. This mode compensates

for lead wire resistance in hardware if all the lead wires have the same

resistance. A gain of 2x is applied to the voltage across the negative lead

wire and the ADC uses this voltage as the negative reference to cancel the

resistance error across the positive lead wire. Refer to Figure 13 for an

illustration of the connections.

2-Wire Resistance and Quarter-Bridge Modes

In 2-Wire Resistance and Quarter-Bridge modes, connect the two ends of

the resistor or gauge to the NI USB-9219 across the HI and LO terminals.

These modes source a current, which varies based on the resistance of the

load, between the HI and LO terminals. The resulting resistance is

computed from the voltage measurement. 2-Wire Resistance and

Quarter-Bridge modes do not compensate for lead wire resistance. Refer to

Figure 14 for an illustration of the connections.

Wire

ADC

NI USB-9219

Figure 14. Connections in 2-Wire Resistance and Quarter-Bridge Modes

Half-Bridge and Full-Bridge Modes

Half-Bridge and Full-Bridge modes use the internal voltage excitation to

set the input range of the ADC and return voltage readings that are

proportional to the excitation level. The internal excitation voltage is

nominally 2.5 V but it varies based on the resistance of the sensor. Refer to

the Specifications section for more information about excitation levels.

In Half-Bridge mode, the HI input is referenced to EX–. In Full-Bridge

mode, the ADC reads the HI and LO inputs differentially. Refer to

Figure 15 for an illustration of the connections.

Thermocouple Mode

In Thermocouple mode, connect the positive end of the thermocouple to

HI and the negative end of the thermocouple to LO. This mode uses the

125 mV range of the ADC to return a voltage reading. Use shielded

cables and twisted-pair wiring and ground the shielded cables. Each

channel has a built-in thermistor for cold-junction compensation (CJC)

calculations. For improved CJC sensor accuracy, operate the NI USB-9219

in a stable temperature environment and avoid placing heat sources near the

module or its connectors. Refer to the Specifications section for more

information about accuracy. The NI USB-9219 does not support open

thermocouple detection. Refer to Figure 16 for an illustration of the

connections.

Excitation Protection

The NI USB-9219 excitation circuit is protected from overcurrent and

overvoltage fault conditions. The circuit is automatically disabled in the

event of a fault condition. Whenever possible, channels automatically

recover after the fault is removed. Refer to the software documentation for

information on how an excitation fault is displayed and handled.
