dataTaker data loggers are used in a wide variety of applications around the world. Many of these are relatively low channel count applications. The dataTaker CEM20 channel expansion module is available when you have need for a large number of analog inputs in your data logging application.
Each physical analog input channel of a dataTaker is a 4 wire input. Each physical channel can be configured for a single three or four wire sensor, two 2-wire differential sensors or three common ground reference sensors. The CEM20 multiplexes a single logger’s analog input to 20 inputs. Each of the inputs on a CEM20 can be configured the same as the physical channel of the loggers. You can connect a CEM20 to each of a base unit’s physical channels. This means that a DT80 application can scale to 300 analog inputs; a DT85 can scale to 960 analog inputs.
