2-Digit Up/Down Counter Module (100mm Digits)

The Cebek CD-20 module is a 2-digit UP/DOWN counter with reset and large 100mm high display comprising 84 x 5mm bright red LEDs.

The counter starts at zero and increases by one digit (up to a maximum of 99) each time a count impulse is received. It can also count down, subtracting from the count.

Count input accepts a simple make contact closure (e.g. a push button, relay closure) or injection of an external pulse (5Vdc). The board also has a Reset input to zero the count and display.
