Module-DI20C

High Speed counter Input

Input 8,9 provides counters, with up to 5 kHz counting frequency @ 50% duty cycle. 

A user programmable debounce filter, in 1 ms units, is provided for each digital input, to filter out noise or mechanical relay bounce. This could also be used in combination with software counters, in case a low frequency mechanical contact is used for counters.
