8 channel, 24-bit fully isolated simultaneously sampling A/D board

The DNx-AI-218 is an 8-channel fully isolated, simultaneously sampling A/D board. It features 24-bit resolution and 7 software selectable input ranges. Each channel also includes an isolated logic-level DIO bit.

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.

Each channel is electrically isolated from all other channels as well as from the Cube or RACKtangle chassis. In addition to the isolation, each input 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-218 ideal for use in redundant measurement/control applications.
All connections to the DNx-AI-218 are through a female DB37 connector. OEMs will find it easy to find mating connectors for custom cables, while end-users may take advantage of UEI’s popular DNA-STP-37 screw terminal panel via the DNA-CBL-37 or DNA-CBL-37S series cables.

Software included with the DNx-AI-218 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-AI-218 is a member of UEI's popular Guardian series, which provides high levels of user diagnostics. The AI-218 board provides both the ability to detect input overvoltage conditions as well as the ability to remotely disconnect the channel from field wiring.
