The 2554-A is extremely useful when there is a
requirement to measure rapidly changing pulse
inputs with a high degree of accuracy and convert
them to counts, frequency, or period measurements.
The module can also trigger external events based
on preset counter values and auto-reset the count
without missing an input pulse.

Application
The 2554-A is ideally suited for precise position
measurement applications where an external edge
reset is required. Other applications such as
continuous flow monitoring and interface to
encoders are targeted with the 2554-A.
