PV system performance rating and testing methods require solar irradiance as an input parameter. For PV monitoring applications, Solar Irradiance and PV module temperature are commonly measured. EKO universal 4-20mA and Modbus RS-485 RTU converters give full fexibility to combine different type of sensors within a multi sensor network. Solar radiation sensors and temperature sensors can be easily integrated. Preserve or improve the sensor accuracy while complying to the output standards used in the industry. 

The A-Box-I converts the output voltage of a solar radiation sensor into a 4-20mA current output.

It can be used with all passive EKO sensors or any other irradiance sensor with mV output whenever a 4-20mA signal is required. 

For practical installation, the converter models …
