UEI’s Guardian series boards include a sophisticated, reliable on-board monitoring system, allowing quick and easy system testing, sensor diagnostics monitoring and fault detection for rapid resolution in field or lab.
The DNA-AO-318-210, DNR-AO-318-210 and DNF-AO-318-210 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 DNx-AO-318-210 channel provides an output range of ±10 mA (sourcing) and is capable of up to 400 Ω. For applications requiring voltage outputs please refer to the DNx-AO-308 or DNx-AO-318 series boards.
The DNx-AO-318-210 provides extensive built-in-test diagnostics. An on-board 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 1210 sample FIFO allows each D/A to be updated at up to 10 kHz with slightly derated accuracy, but without data loss. Double buffering the outputs combined with the use of low glitch D/As make the DNx-AO-318-210 an ideal solution for generating low frequency waveforms or providing highly accurate switched stimulus.
Software is included, providing a comprehensive, yet easy-to-use API that supports all popular operating systems, including Windows, Linux, and most real-time operating systems—such as QNX, Intime, VXworks, and more. Additionally, the UEIDAQ Framework—an even higher level driver—supplies complete support for those creating applications in many popular programming languages, as well as data acquisition software packages such as LabVIEW and MATLAB/Simulink, ActiveX or OPC servers.
The DNx-AO-318-210 is a member of UEI's popular Guardian series, which provide high levels of user diagnostics. The AO-318-020 board provides voltage, current and temperature monitoring, field disconnect functionality, and programmable circuit breakers.
