The plug-on display has the following pin assignment:
Power supply
The supply voltage (mostly 24 V DC) must be greater than the sum
of the voltage drop U
s
at the sensor, voltage drop 5 V at the display
and other voltage losses U
a
(such as additional evaluation and line
losses).
Thus, the following applies: U
b
= U
s
+ 5 V + U
a
PIN 1
