This is a low cost 4-digit Up/Down counter. Count range is from 0000, 1, 2 to 9999 (counting up) or 0000, 9999, 9998, . 0001 (counting down). The 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. A 9 to 15V DC supply is required to power the kit, which has a current consumption of 20mA to 40mA, depending on the number displayed.
