USB-240124-bit USB DAQ module for universal inputs
- Manufacturer
USB-2401 is a universal data acquisition module linked over USB, used in thermal testing and in measurements with passive sensors, where each channel can be configured for a different kind of signal.
The inputs accept voltage, current, thermocouples, RTDs, resistive bridges and resistance, with simultaneous sampling on the four differential channels and a maximum frequency of 2 kS/s. The module is powered from the USB bus and wiring lands on two pluggable 20-pin terminal blocks.
