DAQM908A
– 40-Channel Single-Ended Multiplexer
– 80 ch/s scanning
– Single-wire switching for common low
applications
Built-in thermocouple reference junction
Use the Keysight DAQM908A for the greatest density
in common low applications, such as battery test,
component characterization, and benchtop testing.
Each module switches 40 one-wire inputs. All
two-wire internal measurements except current are
supported. The module low connection is isolated
from earth and can float up to 300 V.
DAQM903A
20-Channel Actuator/General Purpose Switch
– SPDT (Form C) latching relays
– 300 V, 1 A actuation and control
This general purpose switch module has 20 independent
single-pole, double-throw (SPDT) relays. Use it to cycle power
to products under test, control indicator and status lights, and
to actuate external power relays and solenoids. Combine it with
matrix and multiplexer modules to build custom switch systems.
Its 300 V, 1 A contacts can handle up to 50 W, enough for many
power line switching applications.
