DNx-AO-318-020, DNA-AO-318-020, DNR-AO-318-020, DNF-AO-318-020

The DNA-AO-318-020, DNR-AO-318-020 and DNF-AO-318-020 are fully isolated, high-precision, 8-channel analog current output board compatible with UEI’s popular “Cube”, RACKtangle and FLATRACK I/O chassis respectively. The boards offer full 16-bit resolution and guarantee monotonicity over the entire operating temperature range. Each DNxAO-318-020 channel provides an output range of 0-20 mA (sourcing) and is capable of up to 400 Ohms. For applications requiring sinking outputs please refer to the DNx-AO-319-420. For applications requiring voltage outputs please refer to the DNx-AO-308 or DNx-AO-318 series boards.

The DNx-AO-318-020 provides extensive built-in-test diagnostics. An onboard A/D converter on each channel allows the user to monitor both output voltage and current. A solid state relay on each output allows the D/A channel to be disconnected from the field I/O so that a complete board self-test can be completed without driving the circuitry connected to the outputs. This relay in combination with the output current and voltage sensing can also be set to disconnect the D/A output in the event of an external fault condition such as a short to ground or a DC power supply.

All 8 channels may be configured to update simultaneously, or they may be updated one at a time as data is written. A 1024 sample FIFO allows each D/A to be updated at 10 kHz without data loss. Double buffering the outputs combined with the use of low glitch D/As make the DNxAO-318-020 an ideal solution for generating low frequency waveforms or providing highly accurate switched stimulus.

Software included with the DNx-AO-318-020 provides a comprehensive yet easy to use API that supports all popular Windows programming languages as well as supporting programmers using Linux and most realtime operating systems including QNX, RTX, VXworks and more. Finally, the UEIDAQ Framework supplies complete support for those creating applications in Windows data acquisition software packages such as LabVIEW, MATLAB/Simulink, DASYLab or any application which supports ActiveX or OPC servers.
