10.4 Analog input modules

Protection circuit of AC-actuated coils
AC-actuated coils are connected to varistors or RC elements as shown in the figure.

Figure 10-5
The protective circuit with varistor has the following properties:
● The amplitude of the trip overvoltage is limited but not attenuated.
● The steepness of the overvoltage remains the same.
● The trip delay is low.
The protection circuit with RC elements has the following properties:
● The amplitude and steepness of the trip overvoltage are reduced.
● The trip delay is low.
