Measured value
The table below shows the admissable measured value range of the analog inputs, depending
on the chosen sensor (incl. physical offset, if applicable). These values are the minimum and
the maximum input values for the customer-specific linearization.
Sensor
RTD temperature probe
Thermocouple
Resistance transmitter
Resistance/potentiometer
Current 0 to 20 mA
Current 4 to 20 mA
Voltage 0 to 1 V
Voltage 0 to 10 V
Voltage 2 to 10 V
NOTE!
In the case of standard signals (current, voltage), the measured value is monitored (incl. phy-
sical offset, if applicable). The current and voltage values that are specified in the table repre-
sent the limits acc. to NAMUR recommendation NE 43. A measured value beyond these limits
causes an overange or an underrange (out-of-range).
Linearization
Depending on the type of linearization, either the domain or the co-domain of the linearization
is monitored.

Linearized value
The linearized value is monitored with respect to the scale range (start, end). As a result, the
range of linearized values (incl. standardized offset, if applicable) is limited as follows:
Lower limit = minimum(start, end) - |end - start| × 0.0125
Upper limit = maximum(start, end) + |end - start| × 0.03125
NOTE!
A linearized value beyond these limits causes an overange or an underrange (out-of-range).
