Keysight DAQM901A 20 Channel Multiplexer (2/4-wire) Module

The Keysight DAQM901A module Data Acquisition System is the fastest switching and scanning multiplexer for general purpose use. It combines dense, multi-function switching with 80 channel/second scan rates to address a broad spectrum of data acquisition applications.

Two- and four-wire channels can be mixed on the same module. Two additional fused inputs (22 channels total) route up to 1A of current to the internal digital multimeter, allowing ac and dc current measurements without the need for external shunt resistors.
