The M-Box converts the output voltage of a solar radiation sensor, PT-100 or 10kΩ NTC temperature sensor into a MODBUS 485 RTU output using the MC-20 Signal Converter. The M-Box can be used with all EKO passive irradiance and temperature sensors and any other sensor with an mV output. With MODBUS, up to 100 sensors and converter units can be addressed and connected in parallel.

EKO’s universal 4-20mA and Modbus RS-485 RTU converters give complete flexibility and the option to combine different types of sensors within a multi-sensor network. Solar radiation and temperature sensors can be easily integrated, preserving or improving sensor accuracy while complying with industry output standards. 

The converter models are housed inside an IP65 aluminium case with universal cable glands and robust input/output screw terminals which can easily connect to any cable and measurement system at the installation site. With A-Box-T Signal Converter, the sensor cable can also be extended over a long distance without any signal loss or potential electromagnetic interference.

In addition, the optional USB controller and EKO Sense software provide access to the converter settings and advanced sensor parameters such as temperature dependency correction and non-linearity correction for adjustment and verification.
