The MC-11 is a 4-20mA digital signal conditioner to convert the Voltage output of a solar radiation sensor into a 4-20mA current output. The converter can be used with all passive EKO radiometers or any other mV sensor to be connected to dataloggers or inverters with a 4-20mA input channel. By using the signal conditioner, the sensor cable can be easily extended over long distances without any signal loss or potential electromagnetic interference in noisy industrial environments.

For easy conversion the converter output for the solar sensor can be set to: 4-20mA = 0 - 1600 W/m2. In combination with a solar sensor the sensitivity factor of the solar sensor will be preset to the converter. With the …
