V2.3
4.2 LPPYRA13AC
CONNECTIONS
The pyranometer LPPYRA13AC has 4…20 mA output and requires 10…30 Vdc exter-
nal power supply. It is to be connected to a power supply and an instrument with
4…20 mA input as shown in fig. 4.2. The load resistance of the instrument reading the
signal must be ≤ 500 Ω .
Connector Function Color
1 Positive (Iin) Red
2 Negative (Iout) Blue
3 Housing White
4 Cable shield Black

4.3 LPPYRA13AV
CONNECTIONS
The pyranometer LPPYRA13AV has 0…1 V, 0…5 V or 0…10 V output (depending on
the ordered output) and requires external power supply: 10…30 Vdc for 0…1 V and
0…5 V outputs, 15…30 Vdc for 0…10 V output. It is to be connected to a power sup-
ply and an instrument with voltage input as shown in fig. 4.3. The load resistance of
the instrument reading the signal must be
≥
100 k Ω .
