This Multifunctional Up-Down Counter SELF-ASSEMBLY electronic kit is ideal for counting people or parts, score keeping, etc. through on-board push buttons or by external pulses. Output activates when user preset value matches count.
The board can also offers two modulo 60 counting modes (hh:mm and mm:ss clocks) using the internal oscillator.
very practical for counting people or parts, score keeping, ...
counts up or down
count input through on-board push buttons or by external pulses
display modes: normal or time (hh:mm and mm:ss)
an internal oscillator allows time measurement
a memory function constantly compares the current value with a preset value and activates an output for as long as both are equal
self diagnostic at power up
comes with easy board-to-wire connector (20cm wire)
counter input voltage: 3...12Vdc (normal dry contact also possible)
EQUAL output: 5Vdc / max. 50mA
max. counting speed: 200 / sec. (2 / sec. with long debounce delay)
max. count: 4 digits (9999 / 23h59m / 59m59s)
power supply: 9 - 12Vdc or transformer 2 x 9Vac / 300mA
