Interface

Board

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 120000kS/s each for AI-217-1 or 30kS/s each for AI-217-803 (up

to 480 kS/s max aggregate rate per 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.

As with all UEI PowerDNA boards, the DNx-AI-217 can be operated in harsh

environments and has been tested at 5g vibration, 50g shock, -40 to +85°C

temperature. Each board provides 350 V

rms

isolation between the board and its

enclosure, or any other installed boards.

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, RTX, 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, DASYLab or any application which supports ActiveX or OPC servers.
