Example: analog value comparator, comparison of two
analog values
To compare two analog values, you can use the following
circuit. In this case, the comparison determines whether I7 is
less than I8.
Parameter settings of the analog value comparator
Counters EZ provides 16 up/down counters C1 to C16 for use as
required. The counter relays allow you to count events. You
can define an upper threshold value as a comparison value.
The contact will switch according to the actual value.
High-speed counters, frequency counters up to 1 kHz counter
frequency.
EZ-DA and EZ-DC feature four high-speed counters C13 to
C16. The function is defined by the mode selected. The
counter input is connected directly to a digital input. The high-
speed digital inputs are I1 to I4.
Possible applications include the counting of components,
lengths, events and frequency measurement.
