About Multiplexers
Multiplexers allow our dataloggers to measure more sensors. The number of analog inputs is increased by sequentially multiplexing sensor leads into "common" leads. The individual common leads are connected to datalogger analog inputs, excitation channels, or ground as required by the sensor. The datalogger controls the multiplexer using two control ports or one control port and one excitation channel.
FAQs for
Are the CR200X, CR206X, CR211X, CR216X, or CR295X dataloggers compatible with SDMs and multiplexers?
The CR200X-series and the retired CR200-series dataloggers are NOT compatible with SDMs or multiplexers. If more channels are needed or may be needed in the future, consider purchasing a CR800, CR850, or CR1000 instead.
