The MODBUS 485 RTU converter called "MC-20" is a digital signal conditioner to convert the Voltage output of a solar radiation sensor, PT-100 or 10kΩ NTC temperature sensor into a MODBUS 485 RTU output. The converter can be used with all passive EKO radiometers or any other mV sensor to be connected to data loggers or inverters with a MODBUS 485 RTU 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. With MODBUS up to 100 different sensors and converter units can be addressed and connected in parallel.

The mV signal of the solar sensor will be converted to irradiance …
