mA Input Module for the Data Blogger

The milliAmp input module for the Data Blogger provides three electrically isolated 4 to 20mA inputs. The system is "loop powered" so the current source is not provided by the Blogger. The Input Module is factory calibrated to give a result in milliAmps. The user can give each channel of the Blogger a separate offset and gain to turn 4 to 20mA units into more useful units like ppm or degC or pH.
