Explanation: A PLC’s high-speed counter is a specialized input module that can count the number of pulses from a sensor, measure the speed of a motor, and monitor the frequency of a signal. This feature is particularly useful for industrial processes that require precise measurement, such as counting the number of parts produced by a machine or monitoring the speed of a conveyor belt.
