The MD (Totalizer) Series is a 4 digits LED Totalizer in a DIN 72 x 72 panel size (Panel Cut-out size: 68 x 68mm). This is a very simple but functional totalizer. With a count speed of 1kHz maximum, this Add only counter accepts Contact or Non-Contact pulse input. The MD (Totalizer) Series can be powered by AC100/110V or AC200/220V, selectable, and it has an external power supply of DC12V for sensors. It has push button reset on the front panel, remote or electrical reset is also available. Memory is optional.
