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 exibility 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-T converts the output voltage of a PT-100 temperature sensor into a 4-20mA current output.

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

For practical installation, the converter models are accommodated inside an IP65 aluminium box with universal cable glands. It has robust input/output screw terminals, which can be easily connected to any cable and measurements system at the installation site. With the signal converter the sensor cable can be extended over a long distance without any signal loss or potential electromagnetic interference.

With the optional USB controller and EKO Sense software the converter settings and advanced sensor parameters (Temperature dependency correction / non-linearity correction) can be applied and verified.
