DAQM901A
20-Channel General Purpose Multiplexer
– 80 ch/s scanning
– Two- and four-wire scanning
– Built-in thermocouple reference junction
– 300 V switching
The Keysight 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 chan-
nels 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.
DAQM902A
16-Channel High-Speed Multiplexer
– Scanning up to 250 ch/s
– Two- and four-wire scanning
– Built-in thermocouple reference junction
The Keysight DAQM902A employs reed relays to
achieve scan rates up to 250 channels per second.
Use this module for high-throughput automated test
applications as well as high-speed data logging and
monitoring tasks.
Sixteen two-wire inputs switch up to 300 V. Two-
and four-wire channels may be mixed on the same
module. User provided shunt resistors are required
for current measurements.
