Eaton EASY-E4 Series User Manual

6. Function blocks
6.1 Manufacturer function blocks
6.1.3 Arithmetic and analog function blocks
6.1.3.1 A - Analog value comparator
General
easyE4 base devices provide 32 analog comparators, A01
through A32.
Analog comparators can be used to compare analog input
values with a reference value.
Operating principle
The following comparisons are available:
Function block input I1 greater than, equal to, or less than function block input I2.
Using the factors F1 and F2 as inputs enables you to amplify and adjust the values of
the function block inputs.
Function block input OS can be used as an offset for input I1.
The HY function block input is used for the positive and negative switching hysteresis of
the input I2.
The contact Q1 switches if the condition of the comparison mode you have selected is
fulfilled.
