Synchro/Resolver Boards Available In Two Models

United Electronic Industries (UEI) has released DNx-AI-255 synchro/resolver interface boards. The 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 range of rotational position or motion applications.

Each board has two fully isolated synchro/resolver channels with independent A/D converters, while each channel offers 16-bit resolution, +/-2.6arc/min accuracy and scan rates up to 4000Hz. The boards are able to operate as a synchro/resolver-input interface or as a simulation-output device - on a per-channel basis. Each of the channels may be configured 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 50Hz to 4kHz 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.
