 10.06.2011 Small and compact, the DAQ-Pack from Acces I/O Products is a multifunction data-acquisition and control system that lets you add portable analog and digital I/O to any PC or embedded system with a USB port. DAQ-Pack furnishes 32, 64, 96, or 128 single-ended or differential analog inputs with sustained sampling speeds of up to 500 kHz and 12-bit or 16-bit resolution. Groups of eight channels at a time can be independently software-configured to accept different input ranges. A real-time internal calibration system allows the unit to compensate for offset/gain errors, giving a more accurate reading. Signal-conditioning options include unipolar and bipolar ranges of 1 mV, 5 mV, 10 mV, 20 mV, and 50 mV; RC filtering; current inputs, RTD measurement, bridge completion, thermocouple break detection and cold junction compensation, voltage dividers, and sensor excitation.
