Uni­ver­sal sin­gle-cir­cuit con­troller / tem­per­a­ture con­troller

The PMA KS42-1 tem­per­a­ture con­troller has been devel­oped for gen­eral con­trol tasks in all indus­trial sec­tors. The device allows a choice of con­trol modes, includ­ing sim­ple two-point con­trol (on/off), con­tin­u­ous PID con­trol or three-point step con­trol. The process value is recorded via a uni­ver­sal input, while a fur­ther ana­log input is used to mea­sure the heat­ing cur­rent or as an exter­nal set­point input.

The PMA KS42-1 is equipped with three process out­puts, which can con­sist of either three relays or two relays and one uni­ver­sal out­put. The uni­ver­sal out­put can be used to oper­ate an SSR relay, as a con­tin­u­ous current/voltage out­put or to sup­ply a 2-wire trans­mit­ter.

The con­troller is par­tic­u­larly rec­om­mended for indus­trial appli­ca­tions such as ovens and fire­places, burn­ers and boil­ers, plas­tics pro­cess­ing and dry­ers.


Func­tions and spe­cial fea­tures


  • Uni¬≠ver¬≠sal ver¬≠sion continuous/switching, i.e. reduced stock keep¬≠ing
  • Freely con¬≠fig¬≠urable ana¬≠log out¬≠put, e.g. as actual value out¬≠put
  • 100 ms cycle time, i.e. also suit¬≠able for fast routes
  • Cus¬≠tomer-spe¬≠cific lin¬≠eariza¬≠tion for all input types
  • High secu¬≠rity thanks to pass¬≠word pro¬≠tec¬≠tion and inter¬≠nal switch
  • Extended tem¬≠per¬≠a¬≠ture range up to 60 ¬įC enables instal¬≠la¬≠tion close to the process
  • Mea¬≠sured value cor¬≠rec¬≠tion as off¬≠set or 2-point
  • Emer¬≠gency oper¬≠a¬≠tion in case of sen¬≠sor break by tak¬≠ing over the aver¬≠aged out¬≠put level
  • Log¬≠i¬≠cal link¬≠ing of the dig¬≠i¬≠tal out¬≠puts, e.g. for col¬≠lec¬≠tive alarms
  • Pro¬≠gram¬≠mer with four seg¬≠ments and end sig¬≠nal
  • RS422/485 Mod¬≠bus RTU inter¬≠face
  • Built-in trans¬≠mit¬≠ter power sup¬≠ply
  • Water¬≠proof front ‚Äď IP65


The KS42-1 con­troller is designed as a plug-in device. This means that the devices can be replaced quickly, eas­ily and with­out tools.



Self-opti­miza­tion quickly and reli­ably deter­mines the opti­mum con­trol para­me­ters for fast and over­shoot-free reg­u­la­tion when the sys­tem starts up. For heating/cooling con­trollers, the para­me­ters for cool­ing are deter­mined sep­a­rately in order to achieve opti­mum adap­ta­tion there too.


Oper­a­tion and dis­play

The 10 LEDs on the front reli­ably indi­cate the oper­at­ing sta­tus, oper­at­ing mode and error mes­sages.
The automatic/manual but­ton is used to switch the con­troller to man­ual mode with­out any con­fus­ing oper­at­ing sequences.
This can also be locked or the but­ton can be used to start the timer, for exam­ple.


Inter­face and engi­neer­ing tool

Set¬≠tings can be made via the front panel as well as via the Blue-Port¬ģ front inter¬≠face and the Blue¬≠Con¬≠trol¬ģ soft¬≠ware.
