PMA KS90-1 Process con­troller

The indus­trial and process con­troller PMA KS 90-1 is suit­able for pre­cise and cost-effec­tive con­trol tasks in all areas of indus­try. You can choose between sim­ple on/off con­trol, PID con­trol and motor step con­trol. The actual value sig­nal is con­nected via a uni­ver­sal input. The sec­ond ana­log input is used for heat­ing cur­rent mea­sure­ment, as an exter­nal set­point input or as posi­tion feed­back from motor step con­trollers.

The optional third input serves as a uni­ver­sal input for a vari­ety of func­tions, such as tem­per­a­ture-depen­dent set­point cor­rec­tion or dif­fer­en­tial con­trol.

O² mea­sure­ment and con­trol

The PMA KS90-1 and PMA KS92-1 can be used as stan­dard for oxy­gen con­trol with heated and unheated O² probes. The dis­play range is 0.001 ppm…100% O². The unit (ppm / %) is shown auto­mat­i­cally in the four-digit dis­play. From the high-resis­tance (>200M) and the probe tem­per­a­ture (INP3), the O² con­cen­tra­tion is cal­cu­lated accord­ing to Nernst’s equa­tion, dis­played and con­trolled if nec­es­sary. For heated probes, the ref­er­ence tem­per­a­ture is entered as a con­stant.
A fil­ter <999.9s can be set to sta­bi­lize the O² dis­play. The cal­i­bra­tion sup­ports the input of cor­rec­tion val­ues (off­set or two-point) in ppm or %O².


PMA KS90-1 Dis­play and oper­a­tion

The Day & Night dis­play is char­ac­ter­ized by par­tic­u­larly high con­trast in both dark and bright sur­round­ings. The sta­tus fields reli­ably dis­play oper­at­ing sta­tuses, oper­at­ing mode and error mes­sages and the plain text dis­play presents var­i­ous process val­ues numer­i­cally or as a bar graph.


Each PMA KS90-1 has four process out­puts: either relays or up to two uni­ver­sal out­puts, which can be con­fig­ured to con­trol solid state relays, as con­tin­u­ous out­puts with cur­rent or volt­age or as trans­mit­ter sup­ply. Two freely usable opto­cou­pler out­puts are avail­able as an option.

Inter­face and engi­neer­ing tool

Set­tings can be made via the front panel as well as via the Blue-Port® front inter­face and the Blue­Con­trol® soft­ware.

Blue­Con­trol® and Blue-Port® are reg­is­tered trade­marks of PMA Prozeß- und Maschi­nen-Automa­tion GmbH
