F.2 Sensor Input Modules
Input peripherals expand sensor input capacity, condition sensor signals, or
distribute the measurement load away from the datalogger.
F.2.1 Analog Input Multiplexers
Analog multiplexers increase analog-input capacity beyond the channels integral
to the CR800. Excitation channels can also be multiplexed.
