LPPYRA02AC[4]
CONNECTIONS
The pyranometer LPPYRA02AC[4] has
4…20 mA
output and requires
10…30 Vdc
ex-
ternal 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
.

LPPYRA02AV[4]
CONNECTIONS
The pyranometer LPPYRA02AV[4] 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
supply and an instrument with voltage input as shown in fig. 4.3. The load resistance
of the instrument reading the signal must be
≥
100 kΩ
.
