Electrical Controls for Pneumatic Knockers
The Impulser was developed by us as an inexpensive accessory for the control of our Pneumatic Knocker. It allows a wide time frame for the break time of 0.5 to 300 seconds and the working time of 0.5 to 60 seconds.
In order to facilitate the setting of short times, the first half of the scale has been stretched. This allows easy selection of a range from 1 to 9.
The Impulser is available as built-on implement type – suitable for bearing rail 35 DIN 46277 – and as instrument for panel mounting with the front dimensions 72 x 48 mm.
Stepping Relais SD04- SD08
The Stepping Relais SD04 and SD08 are electronic control units using a programmable logic controller (PLC) for periodic cycles with switching of 4 or 8 relay outputs, each with one contact, as is required when knocking larger silo systems, filtration systems, dry towers or when cleaning of dust filter tubes.
Each relay output can be cycled with the working time T1 and break time T2 one to four times before the next output is controlled according to the switching time T3. After expiration of the T1, T2, and T3 times on the last relay the step relay begins again with T1 to the first relay after the reset time T4.
The Stepping Relais is delivered with the following time settings standard:
T1= 0.1 sec up to 99.99 hrs (preset: 5 sec)
T2= 0.1 sec up to 99.99 hrs (preset: 1 sec)
T3= 0.1 sec up to 99.99 hrs (preset: 1 sec)
T4= 0.1 sec up to 99.99 hrs (preset: 10 sec)
All time ranges may be changed to seconds, minutes or hours, so that short and long work, pause, repeat and return times can be most optimally adapted to the requirements.
An input for remote control of a switch room or similar is also available.
