Overview

Product overview

Key product information and technical features.

The DAQCard-AO-2DC belongs to National Instruments' legacy PCMCIA DAQCard family. NI's hardware capability tables identify two analog output channels with selectable unipolar 0–10 V and bipolar ±5 V voltage ranges, plus a current-sink output mode.

Software planning is important for this model: NI specifies NI-DAQ 6.9.x or earlier and excludes it from NI-DAQmx and Traditional NI-DAQ 7.x support. Consult the archived driver support matrix before selecting a host operating system.

Two analog output channels, addressed as channels 0 and 1.
Software-selectable 0–10 V and ±5 V voltage output ranges.
Current-sink output functionality for current-loop operation.
PCMCIA interface within the NI DAQCard product family.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

How many analog output channels does the DAQCard-AO-2DC have?

NI lists two analog output channels, numbered 0 and 1, with software-selectable 0–10 V and ±5 V voltage ranges.

Can this card use NI-DAQmx?

No. NI identifies the DAQCard-AO-2DC as unsupported by NI-DAQmx and Traditional NI-DAQ 7.x and specifies NI-DAQ 6.9.x or earlier.

What current-sink range should be used for system design?

The reviewed NI references conflict: revision A of the LabVIEW Function and VI Reference Manual lists 0–10 mA, while revision B lists 0–20 mA. Confirm the applicable hardware specification before connecting a current-loop circuit.
