An analog comparator is a function block in the programmable logic controller (PLC) that compares two analog inputs and outputs a Boolean result based on the relationship between the two inputs.
The analog comparator block typically has two inputs, a reference input and a comparison input, and one output. The output is set to "1" if the comparison input is greater than, less than, or equal to the reference input, depending on the programmed comparison condition.
Analog comparators are used in a variety of applications, such as control systems, data acquisition systems, and process control systems. They can be used to perform threshold detection, limit checking, and range monitoring, among other things.
In the Siemens Logo! PLC, for example, the analog comparator is represented by the FC 16 block, which is used to compare two analog inputs and generate a Boolean output based on the comparison result.
