The family of electronic counters is very large and has numerous and variable applications. The most popular are the simplest progress counters or progress-reversible counters, which count individual impulses detected at the inputs to the device and which, for example, can be used to adjust the status of the equipment they monitor. The electronic counters are designed to count impulses that represent specific physical quantities, such as the number of completed rotations, blows, strokes, travel, as well as completed data, products, activations, etc. The modern design enables the easy automation of manufacturing processes, with the possibility of programming of adjustable records. The input relay signal can control any manufacturing process, such as proportioning, filling, weighing, or positioning.
