Preset counters are useful in applications where it is important to monitor a specific number of counting operations. The counters are used, for example, in production automation, machine control, and measurement and control technology.

How do prepaid meters work?

Preset counters work by counting digital signals and using a preset value to trigger specific actions. These are the basic modes of operation:

1. Counting process: The prescaler counter counts pulses or events that are fed to it. These pulses can come from various sources, such as switches, sensors or other digital signals.

2. Preset value: The user can set a specific value (preset) that specifies how many pulses are to be counted before a specific action is performed. This value can often be entered using buttons or a digital interface.

3. Counter reading: The counter increases with each pulse received. When the counter reading reaches the preset value, a defined action is triggered, such as resetting the counter to zero, activating an output signal or sending an alarm.

4. Reset: Once the preset value has been reached, the counter can be reset manually or automatically. A new counting process is then started.

Preliminary counters are useful in many applications for counting events, such as in industrial automation, manufacturing, traffic monitoring and many other areas.
