The Cebek CD-21 module is a 4-digit UP / DOWN counter with Reset and a large 58mm (2.3") LED display board.
Count starts at zero and increases by one digit (to a maximum of 9999) 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 counter has a Reset input to zero the count and display.
The counter comprises a control board and separate display board connected by a 20cm ribbon cable to allow versatile mounting options.
Also available with 13mm, 25mm and 100mm display board sizes (see table below).
