Predetermining Counters - Subtracting

Kuhnke Predetermining Subtracting Pneumatic Counters show one line of display You set your starting display by using the mechanical push buttons. Pnuematic pulses are counted and the display then counts down from your predetermined start, to zero. A pneumatic output is then generated, which remains "on" until reset.

There are 4 models to choose from in this range. Each is panel mounted with a manual reset button the the front that can be locked out. Choose between a 3 digit or 5 digit display and then choose M5 threaded ports or ports with 4mm push in connections.

We recommend and stock M5 ported versions for added security within control panels. You will find equivalent RS products offer only the 4mm push-in versions. We can supply both and advise you on the best for your application. Protective covers are available.
