Compact filter valve control, preferably for 110/230 VAC and 24 VAC AC valves, but also suitable for 24 VDC DC valves. Adjustable pulse and interval times and control inputs, e.g. for our differential pressure regulator types DDD, DDU and DPQ and our differential pressure switch DW.

Examples: JET - Filter systems, where the filters are cleaned by compressed air pulses via air valves.

The filter cleaning can be started by switching the mains voltage ON-OFF or by an external contact at terminals 11 (START1) and 15 or 10 (START3) and 15, with PULSE 1 and PAUSE 1 or PULSE 3 and PAUSE 3 for the valves. The pulse and interval times can be set very precisely via the keyboard.

The START1 and START3 function can also be controlled with 24 VDC signals e.g. from a PLC or with our differential pressure controllers and differential pressure switches. Two relay outputs can be used for various operating or fault signals.

TRANS-FILTER-SCANNER TFS-12S controlled cleaning process guarantees a longer service life for the filters and economical use of energy, saves compressed air for cleaning, ensures economical operation of the filter system and the system units.
