USB-2401 4-CH 24-Bit Universal Input USB DAQ Modules Introduction The USB-2401 is a 24-Bit, 4-channel simultaneous-sampling universal input USB DAQ modules featuring built-in signal conditioning circuitry, providing direct measurement of commonly used sensors including current output transducers, thermocouple, RTD, load cell, strain gauge, and others. Individual channels can be programmed to measure different signal types. The USB-powered USB-2401 is equipped with removable screw-down terminals for easy device con- nectivity, and the included multi-functional stand fully supports desktop, rail, or wall mounting. The USB-2401 is suitable for basic measurement applications requiring high resolution and accuracy, laboratory research and material testing environments, and industrial temperature measurement. U-test, a free ready-to-use testing program is included to enable operation or testing of all ADLINK USB DAQ series functions with no programming requirement.
