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 CR1000. Excitation channels can also be multiplexed.

Table 131. Analog Multiplexers

Model Description

AM16/32B

64 channels - configurable for many sensor types.
Muliplex analog inputs and excitation.

AM25T

25 channels - designed for thermocouples and differential
inputs
