The Instek DAQ-901 is a comprehensive multiplexer for general scanning. The same module can mix 2-wire and 4-wire channels; at the same time, the additional 2 current input channels can be used for AC and DC current measurement without external shunt resistors (maximum 1A per channel). The DAQ-901 - with a total of 22 channels, intensive multi-function switching, and a scan rate of up to 80 channels per second - is suitable for various data acquisition applications.
