Possible connection type for measuring physical quantities
The I
5
and I
6
analog inputs can also be used to measure analog signals (0 / 4 ... 20 mA). The
device inputs must be configured accordingly.
A suitable sensor (0 / 4 ... 20 mA) must be used for this application. The inputs I
5
and I
6
are
passive. A voltage source of ≤ 50 VDC must be connected as shown in the diagram.
Physical quantities of any kind, such as
●
Temperature [°C; °F]
●
Moisture [%]
●
Pressure [haPa]
can be measured.
Note
Refresh time
The refresh time of the measured values can be up to 5 s.
