The Keysight DAQM901A module Data Acquisition System is the most versatile 20-channel multiplexer for general-purpose scanning. It combines dense, multi-function switching with 80 channel / second scan rates to address a broad spectrum of data acquisition applications.
On the same module, two-wire and four-wire channels can be combined. The integrated digital multimeter receives up to 1A of current from two extra fused inputs (a total of 22 channels), enabling ac and dc current measurements without the necessity of external shunt resistors.
Frequently Asked Questions
