HE 5712 – Valve con­trol in com­pact housing

The HE 5712 enab­les the time or dif­fe­ren­tial pres­sure depen­dent con­trol of up to 8 solenoid val­ves in indus­trial dust remo­val tech­no­logy. The val­ves are acti­va­ted sequen­ti­ally and moni­to­red for over­cur­rent and inter­rup­tion. The dif­fe­ren­tial pres­sure is mea­su­red directly by the con­trol­ler, so no exter­nal sen­sor is requi­red.

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

 

 

 

 

 

 

 

 

 

 

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 and time-saving 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 5712 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. In this way, 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.
