The MDR (Totalizer) Series is a 4 or 6 digits LED bi-directional 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 high count speed of 5kHz maximum. This bi-directional counter accepts Contact or Non-Contact pulse input and count modes inlcude Add/Subtract or Quadrature. The MDR (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 and remote reset is also available. Memory is built-in for retention of count values during power loss of the counter.
