Cebek CD-4 module is a 6-digit standard counter. It can count up from 0 to 999999 when it receives impulses from a closing contact on the signal input like a push button or switch or by injecting an external signal (12VDC). The module also has the facility, by throwing a switch, to count down from the displayed count. The module also has a reset signal input, which allows you to reset the count at any time.
