UEI Launches High-Resolution Analogue Input Boards

United Electronic Industries (UEI) has released the DNA- and DNR-AI-217 high-speed, high-resolution analogue input boards. The boards provide 16 fully differential channels of 24-bit, +/- 10V (gain=1) analogue input and one single-ended dedicated channel for thermocouple cold junction compensation. This configuration is said to eliminate the noise and offset errors associated with multiplexed inputs and, at the same time, allows all 16 channels to be sampled simultaneously.

In addition, seven software-selectable gains accommodate a range of input signals. Both boards offer 30kS/s sampling rates per channel and 480kS/s aggregate for an entire board. The DNA version of the board is designed for mounting in any of UEI's six-slot PowerDNA, UEIPAC, UEISIM and UEIModbus 'Cubes'.

The DNR version is designed for use with the six- or 12-slot rack-mounted Halfrack and Racktangle chassis. Software for the DNA/DNR-AI-217 is provided in the UEIDAQ framework. The framework provides an easy-to-use API that supports programming and operating systems such as Windows, Vista, Linux and most real-time operating systems, for example QNX, RTX and RT Linux. In addition, the board is fully supported by Labview, Matlab/Simulink, Dasylab or any application supporting ActiveX, OPC or Modbus TCP control.
