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.

Dataloggers that are compatible with multiplexers include our CR800, CR850, CR10X, CR1000, CR3000, CR5000, CR7, and CR9000X. Please note that our CR200-series and CR510 dataloggers are not compatible.
