Digital-to-Analog (D/A)

 

Modules DA1 – DA4

Modules DA1 – DA4 are NAI’s latest generation Digital-to-Analog (D/A) Modules. They provide a choice of the following conversion capabilities: multi-channel or unipolar/bipolar voltage. Tailored to meet stringent test applications, these modules are used on our multifunction embedded I/O boards and SBCs.

 

The DA1 module features 12 independent D/A output channels with a full-scale range of ±10 VDC at ±25 mA (max). The DA1 provides either voltage or current control loop modes that are programmable for the particular application. The DA1 module also offers external trigger/synchronization signal (RS422/485) capability, which provides/accepts a trigger signal to/from other module(s).

The DA2 module features 16 D/A output channels with a full scale range of ±10 VDC at ±10 mA (max). The DA2 module also offers external trigger/synchronization signal (RS422/485) capability, which provides/accepts a trigger signal to/from other module(s).

 

The DA3 module features four, high-current D/A output channels with a full-scale range of ±25 VDC or ±100 mA (max). The DA3 provides either voltage or current control loop modes that are programmable for the particular application.

The DA4 module features four high-voltage D/A output channels with a maximum full-scale range of ±80 VDC at ±10 mA (max).

The modules/channels include extensive Background Built-in-Test (BIT). In addition to output signal read-back (wrap) capabilities, overloaded outputs are detected with automatic channel shut-down protection, and the results are displayed in a status word. The modules also include D/A FIFO buffering for greater control of the output voltage and signal data. Once enabled and triggered, the D/A FIFO buffer accepts, stores, and outputs the voltage (and/or current) commands for applications requiring simulation of waveform generation (single or periodic). The output data command word is formatted as a percentage of the Full Scale (FS) range selection, which allows maximum resolution and accuracy at lower voltage ranges.
