DNx-AI-255 Synchro/Resolver interface boardsThe DNx-AI-255 Synchro/Resolver interface boards are available in two models—one for use with UEI’s PowerDNA Cubes and another for rack-mounting in a PowerDNR RACKtangle or HalfRACK chassis. Multiple operating modes ensure compatibility with all standard sensor wiring and excitation configurations, making the boards suitable for a very wide range of rotational position or motion applications. Each board has two fully isolated, synchro/resolver channels with independent A/D converters, and each channel offers 16-bit resolution, ±2.6 arc-minutes accuracy, and scan rates up to 4000 Hz. A key feature of the new boards is the ability to operate either as a synchro/resolver input interface or as a simulation output device—on a per channel basis. Each of the channels may be configured either as a synchro/resolver input with internal or external excitation or as a synchro/resolver simulated output. Each simulated output may be used as a software-controlled input stimulus for an avionics test system or flight simulator. Each channel may be configured to output 50 Hz to 4 kHz excitation voltages to the primary of a synchro/resolver device or alternatively as the simulated output voltage from the secondary of a synchro/resolver. In simulator mode, the board uses a software-defined value as the position input for a simulated device. The DNx-AI-255 is fully supported by the company’s comprehensive software suite, which includes factory written support for all popular operating systems (e.g., Windows, Linux, VxWorks), programming languages (e.g., C, C# and VB .NET) and application packages such as LabVIEW, MATLAB, and DasyLAB.
