NI WSN-3202 device. Refer to the Specifications section to ensure compatibility. The Drive High Only
and the Drive High and Low modes require an external power supply connected to the DIO PWR
terminal.
The following sections discuss how to configure the NI WSN-3202 device for different types of input
and output and how to connect external devices to the NI WSN-3202 DIO terminals.
Connecting Sourcing Digital Outputs
You must connect an external power supply to the NI WSN-3202 to source digital outputs. This power
supply provides the current for the devices you connect to the NI WSN-3202. Connect the power supply
positive lead to DIO PWR terminal and the power supply negative lead to one of the D GND pins.
The DIO PWR terminal on the NI WSN-3202 is internally connected to each digital channel. You can
connect only one external voltage supply to the device. Refer to the Specifications section for
information about the power supply voltage range.
Note You must use 2-wire ferrules to create a secure connection when connecting more than one
wire to a single terminal on the NI WSN-3202.
You can connect sourcing digital outputs to the NI WSN-3202 in either Drive High Only Mode or Drive
High and Low Mode. In either mode, connect the device to DIO.x and connect the device common to
the D GND terminal closest to that DIO.x terminal.
Drive High Only Mode
In Drive High Only Mode, the DIO.x terminal is driven to the voltage supplied to DIO PWR when you
turn on the channel. Writing a digital value of 1 turns on the channel, and 0 turns off the channel. The
channel is high impedance (refer to the Digital Input (Tristate Mode) specification) when the channel is
turned off (0). Use this mode for devices that require high side drive or a sourcing output.

Digital I/O Protection
Each digital I/O channel has overcurrent protection specifically to prevent damage due to short circuit
faults.
Understanding Short Circuit Protection
A short circuit fault at the DIO.x terminal may cause a resettable fuse internal to the digital I/O channel
to increase in resistance preventing damage to the equipment. Whether the fuse increases in resistance
depends on factors such as the current level, the temperature, and power supply voltage. High inrush
currents that exist for a short time do not trip the fuse. Refer to the Specifications section for more
information about the maximum continuous output current, short circuit behavior, and short circuit trip
time.
Preventing an Overcurrent Condition
Follow these recommendations to prevent an overcurrent condition:
•Do not connect DIO PWR to ground.
© National Instruments Corporation 23 NI WSN-3202 User Guide and Specifications
•Do not exceed the output current rating of the channel.
•Do not ground unused terminals.

If the node has detected an overcurrent condition, it immediately stops driving the DIO line, goes
to a safe power down state, and blinks a four blink error code. The node must be manually reset or
power-cycled to resume operation. A DIO line can be in overcurrent if it is driving high, or driving low,
but not if it is tristated. To identify which DIO line tripped the overcurrent protection, set all the DIO
lines to tristate and one by one set them to the desired drive mode and value until the protection is
tripped.
Resetting Channels After an Overcurrent Condition
After you have identified and removed the cause of the overcurrent condition, to resume normal
operation, you must reset the node by pressing the RESET button or by removing and reapplying power
to the node.

Absolute Accuracy Formulas
AbsoluteAccuracy = Reading · GainError + Range · OffsetError + NoiseUncertainty
GainError = ResidualGainError + GainTempco · TempChangeFromLastCal
OffsetError = ResidualOffsetError + OffsetTempco · TempChangeFromLastCal + INL_Error
NoiseUncertainty = (3 · RandomNoise)/ for a coverage factor of 3 and averaging
100 points
Absolute accuracy at full scale on the analog input channels is determined using the following assumptions:
TempChangeFromLastCal = 45 °C
NumberOfReadings = 100
CoverageFactor = 3
For example, on the 10 V range, the absolute accuracy at full scale is as follows:
GainError = 10 V · (102 ppm + 31 ppm · 45) = 14.97 mV
OffsetError = 10 V · (164 ppm + 22 ppm · 45 + 100 ppm) = 12.54 mV
NoiseUncertainty = 3 · 342 V
AbsoluteAccuracy = 27.61 mV
