Description

When panel area is limited, and functional simplicity is a key concern, the Series 7441 may be the best predetermining counter for the job. It counts down from a user entered preset value. Upon reaching zero, an output switch is actuated. Manual or remote reset restores the switch and preset value to their original condition.

Setting a preset value into the Series 7441 is direct and easy, yet secured from unintentional change. Just press the reset button to its special latched position, then use the five digit-buttons to set the desired number on the display. If left latched, the reset button will automatically return to its normal position when the first count signal is received.
