High-speed simultaneously sampling A/D board

Product Description

The DNA-AI-217 and DNR-AI-217 are 16-channel simultaneously sampling A/D boards compatible with UEI’s popular Cube and RACKtangle chassis respectively. The DNA/DNR versions are electronically identical and feature 24-bit resolution with 7 software selectable input ranges. The DNx-AI-217 is pin compatible with the popular DNx-AI-207 board and offers an easy upgrade path for those looking for more resolution, higher sample rates or simultaneously sampling inputs.

An A/D per channel configuration allows channels to be sampled simultaneously at rates up to 120 kS/s each (480 kS/s max aggregate entire board). The A/D per channel configuration virtually eliminates input cross talk and channel settling time issues even when connected to high impedance signal sources.

The DNx-AI-217 is fully isolated from the Cube/RACKtangle and is overvoltage protected up to ±40 V (power on or off). The inputs go into a high impedance mode when power is removed making the AI-217 ideal for use in redundant measurement/control applications.

Additionally, the DNx-AI-217 provides a dedicated CJC channel that can be used for reading from the built-in CJC sensor on the DNA-STP-AI-U or AI-207TC terminal panels.

The DNx-AI-217 is a member of UEI’s popular Guardian series, which provide high levels of user diagnostics. The AI-217 board provides both open input detection functionality as well as the ability to detect input overvoltage conditions.

Software included with the DNx-AI-217 provides a comprehensive yet easy to use API that supports all popular operating systems including Windows, Linux, real-time operating systems such as QNX, INtime, VxWorks and more. Finally, the UEIDAQ Framework supplies complete support for those creating applications in Windows based data acquisition software packages such as LabVIEW, MATLAB/Simulink, or any application which supports ActiveX or OPC servers.
