The DNx-AO-318 are fully isolated, high-precision, 8-channel analog voltage output boards, 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 DNx-AO-318 channel provides an output range of ±10 V and is capable of driving ±10 mA. For applications requiring higher output current or voltage, please refer to the DNx-AO-308-35x series boards.
The DNx-AO-318 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 DNx- AO-318 an ideal solution for generating low frequency waveforms or providing highly accurate switched stimulus.
Software included with the DNx-AO-318 provides a comprehensive yet easy to use API that supports all popular Windows programming languages as well as supporting programmers using Linux and most real-time operating systems including QNX, INtime, RT Linux, VXworks and more. Finally, the UEIDAQ Framework supplies complete support for those creating applications in data acquisition software packages such as LabVIEW, MATLAB/Simulink, or any application which supports ActiveX or OPC servers.
The DNx-AO-318 is a member of UEI's popular Guardian series, which provide high levels of user diagnostics. The AO-318 board provides voltage, current and temperature monitoring, field disconnect functionality, and programmable circuit breakers.
