RS485 output:
The RS485 output is isolated. Before connecting the pyranometer to the RS485 network,
set the address and the communication parameters, if different from the factory preset
(see “Configuration” chapter).
Analog output:
In the LPS10MAx models the type of analog output is configurable (default 4…20 mA,
see “Configuration” chapter). The pyranometer power supply and the load resistance
vary according to the type of analog output configured:
Analog output Power supply required Load resistance
0…20 mA 10…30 Vdc ≤ 500 Ω
4…20 mA 10…30 Vdc ≤ 500 Ω
0…1 V 10…30 Vdc ≥ 100 kΩ
0…5 V 10…30 Vdc ≥ 100 kΩ
0…10 V 15…30 Vdc ≥ 100 kΩ
In the event of an anomaly in the measurement (detected measurement outside the
measuring range), the output goes to a value 10% higher than the full scale (e.g., 11
V if the output is 0...10 V or 22 mA if the output is 4…20 mA).
