Keysight DAQM901A – 20 Channel Multiplexer (2/4-wire) Module for DAQ970A and DAQ973A

The Keysight DAQM901A is the most versatile 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.

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

Note: This product is only a module. DAQ970A and DAQ973A mainframes are sold separately.
