Uniยญverยญsal sinยญgle-cirยญcuit conยญtroller / temยญperยญaยญture conยญtroller
The PMA KS42-1 temยญperยญaยญture conยญtroller has been develยญoped for genยญeral conยญtrol tasks in all indusยญtrial secยญtors. The device allows a choice of conยญtrol modes, includยญing simยญple two-point conยญtrol (on/off), conยญtinยญuยญous PID conยญtrol or three-point step conยญtrol. The process value is recorded via a uniยญverยญsal input, while a furยญther anaยญlog input is used to meaยญsure the heatยญing curยญrent or as an exterยญnal setยญpoint input.
The PMA KS42-1 is equipped with three process outยญputs, which can conยญsist of either three relays or two relays and one uniยญverยญsal outยญput. The uniยญverยญsal outยญput can be used to operยญate an SSR relay, as a conยญtinยญuยญous current/voltage outยญput or to supยญply a 2-wire transยญmitยญter.
The conยญtroller is parยญticยญuยญlarly recยญomยญmended for indusยญtrial appliยญcaยญtions such as ovens and fireยญplaces, burnยญers and boilยญers, plasยญtics proยญcessยญing and dryยญers.
Funcยญtions and speยญcial feaยญtures
- Uniยญverยญsal verยญsion continuous/switching, i.e. reduced stock keepยญing
- Freely conยญfigยญurable anaยญlog outยญput, e.g. as actual value outยญput
- 100 ms cycle time, i.e. also suitยญable for fast routes
- Cusยญtomer-speยญcific linยญearizaยญtion for all input types
- High secuยญrity thanks to passยญword proยญtecยญtion and interยญnal switch
- Extended temยญperยญaยญture range up to 60 ยฐC enables instalยญlaยญtion close to the process
- Meaยญsured value corยญrecยญtion as offยญset or 2-point
- Emerยญgency operยญaยญtion in case of senยญsor break by takยญing over the averยญaged outยญput level
- Logยญiยญcal linkยญing of the digยญiยญtal outยญputs, e.g. for colยญlecยญtive alarms
- Proยญgramยญmer with four segยญments and end sigยญnal
- RS422/485 Modยญbus RTU interยญface
- Built-in transยญmitยญter power supยญply
- Waterยญproof front โ IP65
Plugยญgable
The KS42-1 conยญtroller is designed as a plug-in device. This means that the devices can be replaced quickly, easยญily and withยญout tools.
Self-optiยญmizaยญtion
Self-optiยญmizaยญtion quickly and reliยญably deterยญmines the optiยญmum conยญtrol paraยญmeยญters for fast and overยญshoot-free regยญuยญlaยญtion when the sysยญtem starts up. For heating/cooling conยญtrollers, the paraยญmeยญters for coolยญing are deterยญmined sepยญaยญrately in order to achieve optiยญmum adapยญtaยญtion there too.
Operยญaยญtion and disยญplay
The 10 LEDs on the front reliยญably indiยญcate the operยญatยญing staยญtus, operยญatยญing mode and error mesยญsages.
The automatic/manual butยญton is used to switch the conยญtroller to manยญual mode withยญout any conยญfusยญing operยญatยญing sequences.
This can also be locked or the butยญton can be used to start the timer, for examยญple.
Interยญface and engiยญneerยญing tool
Setยญtings can be made via the front panel as well as via the Blue-Portยฎ front interยญface and the BlueยญConยญtrolยฎ softยญware.
