Analog Comparator

Brief description

The output is switched on if the difference between Ax and
Ay exceeds the set threshold value.

Symbol in

Connection

Description

Inputs Ax and
Ay

At the Ax and Ay inputs, ap-
ply the analog signals
whose difference is to be
evaluated.

Use the connectors I7 (AI1)
and I8 (AI2).

Parameter Par:

: Gain in %

Value range 0..1000 %

: Offset

Value range

999

: Threshold value

Output Q

Q is set to 1 if the difference
between Ax and Ay ex-
ceeds the threshold value.

Gain and Offset parameters

Refer to the information in Section 4.3.6 on the Gain and
Offset parameters.
