    4. Introduction 4-1. Main Functions Pyranometer Signal Converter MC-11 is a compact signal converter which converts the voltage signal output (mV) from sensors like pyranometers into current loop signal output (mA). The output range of the current loop is between 4 to 20mA; 4mA is equivalent to 0W/m , 20mA is equivalent to 1,600W/m of solar irradiance.
