Product Description
Counter, PZA Series
Adding counter
- Surface mounting- Panel mounting
Adding counters have 6-digit displays and count upwards, i.e. incoming signals are added.
When the counter is reset, 000 000 appears. A pneumatic signal increments the counter by a half step, and the first half of the digit appears.
After completion of the signal, the second half-step increment occurs and the digit becomes fully visible. The counter can be reset manually by means of a button.
It can also be reset by means of a pneumatic signal. A counting signal may not arrive or be present during the resetting procedure.
Predetermining counter
- Subtracting counting mode- Manual and pneumatic reset
- Protective cover
Predetermining counters count pneumatic signals backwards from a preset number. When zero is reached, the counter generates a pneumatic output signal.
This output signal persists until the counter is reset. The counter is preset by pressing the reset button and simultaneously keying in the preset value.
This value is retained when the counter is reset.
