PMA KS50-1

Uni­ver­sal con­troller PMA KS50-1

The PMA KS50-1 uni­ver­sal con­troller is opti­mized for use in plas­tics pro­cess­ing machines. The uni­ver­sal con­troller can be adapted to var­i­ous tasks: from highly dynamic hot run­ners to slow mold tem­per­a­ture con­trol.

 

Thanks to addi­tional inputs and out­puts, spe­cial func­tions can be called up or tem­per­a­ture release sig­nals issued. In addi­tion, the KS50-1 con­troller series can be quickly inte­grated into an automa­tion envi­ron­ment via the Mod­bus inter­face. 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 KS50-1 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. Two opto­cou­pler out­puts for free use are also avail­able as an option.

The start-up func­tion increases the ser­vice life of high-per­for­mance elec­tri­cal heat­ing ele­ments, such as hot run­ner molds.

 

Boost func­tion

The boost func­tion briefly increases the set value, e.g. to remove “frozen” mate­r­ial residues from clogged mold noz­zles dur­ing hot run­ner con­trol. The con­troller is par­tic­u­larly rec­om­mended for indus­trial appli­ca­tions such as: Plas­tics pro­cess­ing, fir­ing tech­nol­ogy, cli­mate cham­bers, dry­ers, ovens and fire­places, burn­ers and boil­ers.

 

Func­tions and spe­cial fea­tures of the uni­ver­sal con­troller PMA KS50-1

• Uni­ver­sal ver­sion continuous/switching, i.e. reduced stock keep­ing
• Freely con­fig­urable ana­log out­put, e.g. as actual value out­put
• Pro­gram­ma­ble func­tion key
• Extended tem­per­a­ture range up to 60 °C enables instal­la­tion close to the process
• 100 ms cycle time, i.e. also suit­able for fast routes
• High secu­rity thanks to pass­word pro­tec­tion and inter­nal switch
• Mea­sured value cor­rec­tion as off­set or 2-point
• Emer­gency oper­a­tion in case of sen­sor break by tak­ing over the aver­aged out­put level
• Log­i­cal link­ing of the dig­i­tal out­puts, e.g. for alarms
• Cus­tomer-spe­cific lin­eariza­tion for all sen­sors
• Pro­gram­mer with ten seg­ments and end sig­nal
• RS422/485 Mod­bus RTU inter­face
• Built-in trans­mit­ter power sup­ply
• Water­proof front – IP65
• CE, UL and cUL

 

Can be replaced with­out tools

The PMA KS50-1 uni­ver­sal con­troller is avail­able as 1/8 DIN (96 × 45 mm and 1/4 DIN (96 × 96 mm) – total depth 118 mm. As a plug-in device insert, the devices can be exchanged quickly, eas­ily and with­out tools.

 

Self-opti­miza­tion for fast adjust­ment

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.
At the touch of a but­ton, the con­troller deter­mines the opti­mum con­trol para­me­ters at the set­point, with­out oscil­la­tion and with min­i­mal devi­a­tion of the con­trolled vari­able.

 

Oper­a­tion and dis­play of the PMA KS50-1

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 reset saved alarms, for exam­ple. The flex­i­ble func­tion but­ton means that an exter­nal switch can be dis­pensed with in many cases.

 

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
