64 IMAGO F3000 / 10.01
7.4.3 Analog inputs
Up to eight analog inputs are available.
Analog input 1 — 8
Selection/settings Description
Probe type
No function Defines the type of probe/sensor to be connected
to the individual analog input.
Resistance thermometer
Thermocouple
Voltage 0 — 1000mV
Voltage 0 — 10V
Current 0 — 20mA
Current 4 — 20mA
Linearization
Linear Defines the linearization function for the sensor.
The display depends on the type of sensor that has
been set.
Pt100
Fe-Con J
NiCr-Ni K
Fe-Con L
Measuring range
Start -9999 to 0 to +9999 °C/°F For standard signals:
Defines the display value (measurement) for the
start of the input signal range.
(depending on the sensor type
and linearization)
v Data Sheet 70.0101
End -9999 to 0 to +9999 °C/°F The value defines the display value (measurement)
for the end of the input signal range.
(depending on the sensor type
and linearization)
v Data sheet 70.0101
Offset -9999 to 0.0 to +9999 °C/°F The offset is used to correct the measurement
upwards or downwards by a fixed amount.
Examples:
Measured Offset Displayed
value value
294.7 +0.3 295.0
295.3 - 0.3 295.0
The controller uses the corrected value
A
(= displayed value) for its calculations.
This value is not the same as the value
at the point of measurement.
Incorrect use of this function may produce
impermissible values for the control variable.
Humidity calculation
Humidity
calculation
ON The analog input 1 (or one of 3 — 8) is used to
acquire the dry temperature. Analog input 2 is used
to acquire the wet temperature. This two values are
used to calculate the psychrometric humidity.
OFF
Dry temperature Analog input 1 Source for dry temperature
