Low cost Up-Down event counter with 4 digit LED display (expandable to 8 digits). Count either Up or Down from 0000 to 9999.
Inputs are triggered by any make contact so can be used to count pulses from switches, relays, open collector outputs or simply push buttons. For example, a turnstile micro switch or relay output from an infra-red security beam (our kit 3130) counting cars, people or items on a conveyor belt. The input must opened before another count can be registered.
Overflow output pulses low when the count wraps around to zero. This output allows two counters to be connected together to make an 8 digit counter.Specifications
