Keysight DAQM901A Multiplexer Module, 20 Channel, 2x1A Chan, 300 V, 2/4 Wire, DAQ970A/73A Series

20-Channel General Purpose Multiplexer

• 80 ch/s scanning
• Two- and four-wire scanning
• Built-in thermocouple reference junction
• 300 V switching
• Includes Certificate of Calibration

The DAQM901A is the most versatile multiplexer for general purpose scanning. It combines dense, multifunction 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.
