The NI 9683 provides connections for 16 pseudo-differential analog input channels.
Each channel has an AI+ and AI- pin to which you can connect a voltage signal. AI- is internally
connected to the isolated ground reference through a high value resistor.
Connecting Differential and Single-Ended Voltage Signals to the NI 9683
You can connect grounded or floating signal sources to the NI 9683. Connect the positive
voltage signal to AI+ and the negative voltage signal to the AI-.
Figure 9. Connecting a Differential Voltage Signal to a Simultaneous AI Channel
Figure 10. Connecting a Single-Ended Voltage Signal to a Simultaneous AI Channel
NI 9683 Circuitry
The NI 9683 analog channels share a common ground that is isolated from other parts of the
board. The NI 9683 protects each channel from overvoltages. Refer to the Specifications section
for more information about overvoltage protection. The incoming analog signal on each channel
is buffered and conditioned by the differential amplifier and then sampled by a 12-bit ADC.
Each channel has an independent track-and-hold amplifier and ADC that allow you to sample
and convert all 16 channel simultaneously.
Connecting Current Sensors to the NI 9683
You can connect current sensors to the NI 9683 using a termination resistor to convert the current
measurement to a single-ended voltage measurement.
Connect the current sensor output to AI+ and the external power supply COM to the current
sensor common pin (CS COM) on the NI 9683.

To avoid the affect of common mode impedance on the measurement, connect one end of all the
termination resistors to a single, small plane. Then have a single connection from the plane to
the CS COM pin of the NI 9683.
The NI 9683 simultaneous analog inputs have ±10 V and ±5 V input ranges that can
accommodate termination resistor values in a certain range, based on the sensor peak current.
Select the highest possible termination resistor to maximize the dynamic range of the analog
input. Refer to the Specifications section for more information about the analog input range. Use
the following equation to determine the maximum value for the terminal resistor based on the
sensor peak current.
For a current sensor with a peak output current of 70 mA, the maximum termination resistor that
can be used with the NI 9683 is as follows:
Note Using the ±5 V input range can reduce the power dissipation on the
termination resistor by 50% when compared to the power dissipation of the ±10 V
input range.
Scanned Analog Input (Monitoring)
The NI 9683 provides connections for 8 single-ended scanned analog input channels.
Each channel has an AI pin to which you can connect a voltage signal. Scanned analog input and
scanned analog output channels share four GND pins on the dedicated 20-position connector.

Scanned Analog Inputs Accuracy and Bandwidth
Use signal sources with an output impedance of less than 2 kΩ to ensure specified performance.
Large source impedances add to the input resistor inside the NI 9683, which results in increased
settling time and decreases the accuracy of the measurement. Increased input impedance also
results in a decrease of the -3 dB bandwidth.
Half-Bridge Digital Output
The NI 9683 provides connections for 14 half-bridge digital output channels.
Each channel has an half-bridge DO pin to which you can connect a digital input device. An
external power supply referenced to ground of the board must be connected to V
Figure 13. Connecting a Digital Device to a Half-Bridge DO Channel

ext
The NI 9683 has push-pull half-bridge digital outputs, meaning the NI 9683 can sink or source
current. When the channel is ON, the half-bridge DO pin is driven to the external power supply
minus a voltage drop due to the sourced current. When the channel is turned OFF, the half-bridge
DO pin is driven to ground plus a voltage drop due to the sinked current.

pins have dedicated current return pins, GND, which are referenced to the ground of the board.
Figure 14. Connecting a Digital Device to a Sinking DO Channel
The NI 9683 has current sinking digital outputs, meaning that the output pin is driven to ground
(GND) when the channel is ON.
Make sure the devices you connect to the NI 9683 are compatible with the output specifications.
Refer to the Specifications section for information about output voltages.
Increasing Current Drive
Each channel has a continuous output current of 20 mA. If you want to increase the output
current to a device, you can connect any number of channels together in parallel. For example,
if you want to drive 80 mA of current, connect DO<0..3> in parallel as shown in Figure 15. You
must turn all parallel channels on and off simultaneously so that the current on any single
channel cannot exceed the 20 mA rating.

The NI 9683 provides connections for four relay control digital output channels. Each channel
has a relay control DO+ and a current return pin, relay control DO-.
The NI 9683 has current sinking outputs, meaning the relay control DO+ is driven to relay
control DO- when the channel is ON.
You can connect industrial devices such as solenoids, actuators, relays, and lamps to the NI 9683.
Refer to Figure 16 for an illustration of how to connect devices to the NI 9683.
Figure 16. Connecting an Industrial Device to a Relay Control DO Channel
Note Ensure that all the relay control DO+/- pins are held within the safety voltage
levels. A maximum common mode voltage of 30 VDC is allowed at a relay control
DO+/- pin with respect to the GND of the NI 9683. Refer to the Safety section for
maximum voltages allowed for the relay control DO channels.
Note NI recommends using the appropriate cabling for the current return pins
based on the amount of current returned per each relay control DO- output. Refer to
the Specifications section for information about peak and continuous current limits
based on the update rate.
Make sure the devices you connect to the NI 9683 are compatible with the output specifications.

Protecting the Relay Control Digital Outputs from Flyback Voltages
If the NI 9683 is switching an inductive or energy-storing device such as a solenoid, motor, or
relay and the device does not have flyback protection, install a flyback diode.

Selecting a Wire Gauge for Relay Control Digital Outputs
The relay control digital output is capable of sinking 8 A of inrush current for a period of 300 ms
on a 60 second cycle and 500 mA of continuous current. Each channel is functionally isolated
from the other channels and the rest of the board, meaning that each relay control digital output
has a dedicated current return pin.
When using cables, make sure the current rating of the cable is able to handle the expected
current for your application. For example, a typical 28 AWG flat ribbon cable is rated at 225 mA
of continuous current per wire. In order to use the relay control digital outputs at their maximum
current capability, cables within category 24 AWG or lower should be used.
Sourcing Digital Input
The NI 9683 provides connections for 28 simultaneously sampled digital input channels
separated in ports P0 and P1. Ports P0 and P1 are independently powered using separate power
supply pins, VI P0 and VI P1. This allows you to connect the DI to multivoltage systems.
The NI 9683 has sourcing inputs, meaning the DI sources current from the VI P0 or VI P1 to the
sinking output device.The NI 9683 internally limits current signals connected to DI.
Each channel has a DI pin to which you can connect a digital input signal. The supply pins, VI P0
and VI P1, are referenced to the ground of the board. The DI operates in the low range or high
range based on the VI P0 or VI P1 voltage. Refer to the Specifications section for more
information about the low range and high range.
You can only connect 3-wire sinking-output devices to the NI 9683. Connect the sinking-output
device to the DI pin and the external power supply lead to the VI P0 or VI P1.

registers as OFF when the sinking-output is in the OFF range. If no device is connected to the
sourcing DI, the channel registers as OFF. Refer to the Specifications section for more
information about the ON and OFF ranges of the sourcing DI.
Note NI recommends that you leave sourcing DI channels that are not used in your
application unconnected to lower power dissipation through the onboard pull-up
resistor.
LVTTL Digital Input/Output
The NI 9683 provides connections for 32 LVTTL digital input/output channels.
The NI 9683 LVTTL DIO channels connect directly to the FPGA DIO on the
NI sbRIO-9605/9606 and are unbuffered and unprotected. Refer to the Specifications section for
more information about the maximum current.
Caution Operating the LVTTL DIO outside the rated specifications may result in
permanent damage to the FPGA on NI sbRIO-9605/9606.
Figure 19. Connecting to the LVTTL DIO Channels
If overshoot and undershoot aberrations and signal integrity are concerns for your application,
use a single load per line that does not exceed 25 pF. For edge sensitive signals, use channels
DIO0 through DIO15 for better signal integrity and crosstalk performance since these channels
have an individual GND pin.
The LVTTL DIO channels on the NI 9863 are routed with a 55 Ω characteristic trace impedance.
Route all external circuitry with a similar impedance to ensure the best signal quality.
You should perform signal integrity measurements to test the effect of signal routing and cable
type on your application. To meet defined power-up states for outputs, use a pull-up or pull-down
resistor on the line.
