Valve con­trol in com­pact hous­ing for use in ATEX Zone 22

The basic unit HE 5731 enables the time or dif­fer­en­tial pres­sure depen­dent con­trol of 16 sole­noid valves in dedust­ing sys­tems.



The con­trol unit HE 5731

  • Menu- and pro­gram­ming-free para­me­ter­i­za­tion
  • Oper­a­tion via mem­brane keys
  • Intu­itive oper­a­tion due to clear sym­bols and dif­fer­en­tial pres­sure level dis­play
  • Three-digit dig­i­tal dis­play
  • Screw­less con­nec­tion tech­nol­ogy
  • Device ver­sion also avail­able as time con­trol



Mod­u­lar expand­able

With three exten­sion units, 64 valves can be con­trolled. The valves are acti­vated sequen­tially and mon­i­tored for over­cur­rent and inter­rup­tion.

Intu­itive oper­a­tion

The lan­guage-inde­pen­dent sym­bol labelling enables the con­trol sys­tem to be used world­wide.


  • Clear sta­tus dis­play with LEDs
  • Sim­ple oper­a­tion with­out com­pli­cated menu struc­tures










Exter­nal dif­fer­en­tial pres­sure mea­sure­ment

The dif­fer­en­tial pres­sure is mea­sured exter­nally and trans­mit­ted as a 4…20 mA sig­nal to the higher-level con­troller (does not apply to devices with pure time con­trol). The sig­nal can be con­nected to the mas­ter as well as to one of the exten­sion units. Fur­ther­more, it is pos­si­ble to con­nect the 4…20 mA sig­nal e.g. to an exter­nal dis­play unit. For this pur­pose, the indi­ca­tor is con­nected in series with a dif­fer­en­tial pres­sure trans­mit­ter(e.g. HE 5409) accord­ing to the wiring dia­gram. If gal­vanic iso­la­tion is nec­es­sary, an iso­la­tion ampli­fier (e.g. HE 501/HE 502) should be used.


Con­ve­nient para­me­ter­i­za­tion

The con­trol sys­tem can be para­me­ter­ized via the mem­brane key­pad or option­ally with the Easy­Tool Con­trols soft­ware. With Easy­Tool Con­trols, para­me­ter data sets can be trans­ferred to the con­troller eas­ily and quickly. This is par­tic­u­larly con­ve­nient when a num­ber of con­trollers have to be recorded with the same data sets.


Prac­ti­cal: Flex­i­ble mount­ing for reduced cabling

The mod­u­lar con­cept of the HE 5731 allows the con­trol unit to be mounted sep­a­rately from the oper­at­ing unit. The con­trol unit can be mounted up to 100 meters away from the con­trol unit so that the con­trol unit is in the user’s field of vision. This means he always has the sta­tus dis­play in view and can react quickly if nec­es­sary. The con­trol unit with the valve con­nec­tions remains close to the valves, which sig­nif­i­cantly reduces the amount of cabling required.


The sep­a­rately avail­able con­nec­tion set with match­ing cable glands and the pre-assem­bled cables with valve plugs in var­i­ous lengths are a use­ful addi­tion to the con­trol sys­tem.
