Description

The Veeder-Root VersaCount 1/16 DIN size multifunction counter is a versatile counter, whatever your application, timing, counting, rate measuring, position indicating, volume measurement, speed monitoring, length cutting or batch, shift, pulse or piece counting. The highest count frequency in the industry enables the VersaCount to perform in applications not previously possible with an electronic counter. The VersaCount features an unprecedented prescaler accuracy to one tenthousandth. Further, automation and precision control are achieved using three presets with relay hold times programmable up to ten minutes. Veeder-Root is the first in the industry to offer a programming assistant where applications can easily be created, archived and printed using the proprietary Programming Assistant software.
