NI WSN-3226 User Guide and Specifications

Note

You can connect only one external DIO PWR supply to the NI WSN-3226.

The power supply provides the current for the devices you connect to the NI WSN-3226. Connect the 
power supply positive lead to DIO PWR terminal and the power supply negative lead to one of the 
DGND terminals. The DIO PWR terminal on the NI WSN-3226 is internally connected to each digital 
channel. Refer to the 

Specifications

 section for information about the power supply voltage range.

Note

Th

Drive High (Sourcing)

 and 

Drive High and Low (Sinking and Sourcing)

 modes require an 

external power supply connected to the DIO PWR terminal.

Drive High (Sourcing)

Drive High (Sourcing) mode is for devices that require high side drive or a sourcing output. When using 
this mode:

Connect the device to DIO

x

 and connect the device common to the DGND terminal corresponding 

to that DIO

x

 terminal. 

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 when the channel is turned off (0).

Drive Low (Sinking)

Drive Low (Sinking) mode is for devices that require low side drive or a sinking output. When using 
this mode:

The DIO

x

 terminal is pulled to DGND when you turn on the channel. 

Writing a digital value of 0 turns on the channel, and writing a digital value of 1 turns off the 
channel.
