MC-20 Signal Converter
- MODBUS 485 RTU Digital Signal Conditioner
Overview
The MC-20 digital signal conditioner converts the voltage output of solar radiation sensors, PT-100 and 10kΩ NTC temperature sensors into a MODBUS 485 RTU output. The converter can be used with all passive EKO radiometers or any other mV sensor that needs to be connected to a data logger or inverter with a MODBUS 485 RTU input channel. With MODBUS, up to 100 different sensors and converter units can be addressed and connected in parallel.
With the MC-20, the sensor cable can easily be extended over long distances without any signal loss or potential electromagnetic interference in noisy industrial environments. Robust input/output screw terminals can also be easily connected to the signal cable leading to any on-site measurement systems. Users can also quickly check and change their converter settings with the optional USB controller and EKO Sense software.
