KS Vario – Multi-chan­nel con­trol sys­tem

The KS Vario multi-chan­nel con­troller of PMA is ideal for tem­per­a­ture con­trol on machines in con­junc­tion with PLC sys­tems and offers a wide range of field­bus con­nec­tions to enable easy inte­gra­tion into exist­ing automa­tion sys­tems. The con­troller can also be used as a stand-alone sys­tem, for which suit­able touch oper­at­ing ter­mi­nals are avail­able. The sys­tem is designed to be cost-effi­cient by com­bin­ing the required mod­ules and can be expanded pre­cisely up to 30 con­trol loops.


Con­troller func­tions: KS Vario can be con­fig­ured as

  • Sig­nal­ing device with 1 or 2 out­puts
  • Two-posi­tion con­troller with DPID behav­ior
  • Three-point con­troller with DPID/DPID behav­ior
  • Three-point con­troller with spe­cial out­put algo­rithm for water evap­o­ra­tion cool­ing (for extrud­ers)
  • Split range con­troller
  • Con­tin­u­ous con­troller
  • Motor step con­troller
  • Cas­cade con­troller


Fur­ther func­tions:

  • Self-opti­miza­tion
  • Start-up cir­cuit
  • Guided wed­ding
  • Boost



  • Mechan­ics in I/O sys­tem style, small­est mod­ule: 12.2 x 120 x 71.5mm
  • Up to 30 mea­sure­ment inputs for ther­mo­cou­ples, PT100, mV, V and mA
  • Var­i­ous out­puts for con­trol and sig­nal­ing
  • RS485 Mod­bus, Eth­er­net Mod­bus TCP, Profibus, Profinet, Ethernet/IP and CANopen com­mu­ni­ca­tion
  • Free assign­ment of the mea­sure­ment and con­trol sig­nals to the con­trol chan­nels
  • Addi­tional mea­sure­ments and sig­nal­ing can be inte­grated
  • Highly mod­u­lar expan­sion options
  • Inte­grated heat­ing cir­cuit mon­i­tor­ing (also par­tial fail­ure and SSR short cir­cuit)
  • CE, UL and cUL

KS Vario is max­i­mally mod­u­lar

The KS Vario base mod­ule already has I/Os for up to 8 con­trol loops on board. By plug­ging in addi­tional I/O mod­ules, the sys­tem can be expanded inex­pen­sively and with fine mod­u­lar­ity up to max. 30 Expand con­trol loops. In the max­i­mum con­fig­u­ra­tion, up to 60 ana­log out­puts and up to 34 ana­log inputs and up to 320 dig­i­tal inputs or out­puts can be processed per bus cou­pler.

Any field­bus bus cou­pler, in which the power sup­ply for the sys­tem is also inte­grated, is plugged in as the head of a sys­tem.


Time sav­ing thanks to auto­matic cross-wiring

The required mod­ules of the KS Vario sys­tem are sim­ply plugged together with­out tools. All periph­eral and aux­il­iary volt­ages and data sig­nals are auto­mat­i­cally cross-wired.


The 24 V DC sup­ply for the sys­tem only needs to be fed in at one point on the bus cou­pler. The attached ten­sion clamp ter­mi­nals for the I/O wiring make it very easy to replace I/O mod­ules. The I/Os can be con­ve­niently labeled using label­ing fields.
