Pulse counters accurately count input signal pulses. Their main purpose is to determine the speed, position and/or direction of objects, making them ideal for control systems, and for tracking moving machinery and vehicles.
Pulse counters offer various configuration options to meet different requirements. They feature a signed, 31-bit counter that can be configured to count the rising, the falling, or the rising and falling edges of pulsed input signals. They can also count in ascending or descending order, which can be controlled by a digital input signal or within Simulink.
In addition, the pulse counter features a configurable debounce to ensure that only valid pulses are counted. This is particularly useful in noisy environments and for equipment which are not correctly impedance-matched.
The pulse counter functionality can be used with all configurable I/O modules that have digital I/O lines. While it is commonly used on TTL lines, it can also be used on differential lines, making it a versatile solution for multiple applications.
