UEI Intros 2-Channel Synchro/Resolver Interface Boards
Synchro/resolver controllers.
Walpole, MA — United Electronic Industries (UEI) has released its DNx-AI-255 Synchro/Resolver interface boards. The boards are available in two models — one for use with the company's popular 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 4000Hz.

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 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.
