Analog Comparator
Available functions:
I7 I8, I7 I8
I7 Setpoint, I7 Setpoint
I8 Setpoint, I8 Setpoint
The analog comparator can compare voltages from 0V to 10V
(setpoints “0.0” to “10.0”).
Parameter Displays for Analog Comparators
Compare inputs I7 and I8.
TIP
Analog signals of sensors typically fluctuate by
several millivolts. For stable switching the setpoints
should differ by at least 0.2V (switching hysteresis).
Do not use any relay with output energize or
impulse relay coil functions.
