With multiple operating modes, the DNx-AI-255 Synchro/Resolver interface boards (from United Electronic Industries) are compatible with all standard sensor wiring and excitation configurations. 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. 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. From $3,500.
