Input Terminals
Actual Value
• Analog I 4 - 20 mA
• Analog I 0- 20 mA
• X1/2:
Sensor 1
• X1/5:
Sensor 2
It is determined by a current signal
connected to the given input
terminal.
Analog U 0-10 V
• X1/2:
Sensor 1
• X1/5:
Sensor 2
It is determined from a voltage signal
connected to the given input
terminal.
P420 SENSOR RANGE
G
Sets the end range value (20 mA or 10 V) of the connected sensor.
P420 SENSOR RANGE

Right fct.
In particular, the end range value (20mA or 10V) shall be always equal to the 100% of the
sensor range (i.e. for a 0.4bar differential pressure sensor, will be 20mA=0.4bar)
P425 SENSOR CURVE
Sets the mathematical function (curve) to determine the Actual Value based on the Sensor
signal.
