4 Digit Presettable Down Counter w/ Output Electronic Kit from DIY Electronics This is a low cost 4 Digit Presettable Down Counter with output and reset. The count input can be used for both high and low speed counting applications. The counter has four modes of operation that control how the output behaves when the count reaches zero. The input, output and power supply pins are brought out to a 10-way header strip for easy connection. A 9 to 12V DC supply is required to power the kit, whichhas a current consumption of 20mA to 40mA, depending on the number displayed. A 12VDC / 150mA plug pack will do fine. The OUTPUT goes low when the count reaches 0000. It stays low until the next valid count input when it goes high again. Catalog number: 12575. Brand: DIY Electronics. Brand's Part Number: K154.
