The CompactDAQ system offers an eight-slot chassis that accepts I/O modules capable of measuring up to 256 channels of electrical, physical, mechanical and acoustic signals in a single system. By combining the plug-and-play simplicity of USB with the performance and flexibility of modular instrumentation, CompactDAQ is designed to provide fast and accurate measurements in a small, simple and affordable system. The system delivers connectivity and signal conditioning for measurements including voltage, temperature, strain, sound and vibration, as well as digital I/O and switching. All modules are hot-swappable and autodetectable for simplified set-up, and offer up to 2,300 Vrms of isolation to ensure PC and user safety. The system delivers up to four dedicated USB signals streams for synchronous analog and digital I/O for data-intensive applications.
