Analog Input GN110, GN111, GN112 and GN113 (Transmitter)
Input overload protection
Overvoltage impedance change
The activation of the overvoltage protection system results in a reduced input impedance.
The overvoltage protection is not active for as long as the input voltage remains less than
200% of the selected input range or 250 V, whichever value is the smallest.
