5.3. OPTION 2 ANALOG INPUTS
Only for the Plus version. This option allows up to two
analog sensors to be connected in order to measure
dierent magnitudes (pressure, solar radiation, soil
moisture content, temperature, etc.). A record is made
of the sensors every 10 minutes that can be queried
from the VEGGA / Agrónic APP / Agrónic PC platforms.
It allows the sensors to make measurements, gener-
ating electrical current from 0/4 to 20 mA or voltages
between 0 and 20 volt..
Connection of 2 analog sensors
The wiring in this option has one switch per sensor to
select the measurement using current or voltage. The
default is current, ‘ I ’ position, to select voltage, set it
to the ‘ V ’ position.
The wiring is housed behind the keypad. The location
to connect the sensors must be indicated in ‘Function -
4. Parameters - Installer’.
Terminal 1 Sensor cable A1
Terminal 2 Sensor cable A2
Terminal 3 It corresponds to the output cable for powering the sensors, 12 Vdc, 200 mA.
Terminal 4 Common for the sensor inputs and common for the power supply output (0 V).
