The DNR-AI-218 is 8-channel fully isolated, simultaneously sampling A/D board compatible with Cube and RACKtangle® chassis respectively. The DNA/DNR versions are electronically identical. The DNA-AI-218 and DNR-AI-218 feature 24-bit resolution, and 7 software selectable input ranges. Each channel also includes and 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, RTX, 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, DASYLab or any application which supports ActiveX or OPC servers.
