2500 High Performance Controller

Single-loop microprocessor controller, formaat 96 x 96 (1/4 DIN), geschikt voor processen met hoge variatiesnelheid. Dankzij zijn uitgebreide functies en configureerbare hardware en software, voorziet hij hoge flexibiliteit in systemen die druk, kracht, temperatuur en differentiële druke controleren en monitoren, en kan hij tot 4 variabelen verwerven. Hij heeft twee analoge hoofdingangen, configureerbaar voor strain gauge / potentiometer / linear signal / TC / RTD (een van hen is optioneel) en twee analoge hulpingangen voor lineare signalen (bvb. remote setpunt functies en lijnsnelheid referentie ingang). Twee analoge geïsoleerde uitgangen (één is optioneel) zijn beschikbaar voor contole. The operator interface, with IP54 protection level (IP65 with protective cover) is equipped with a 6-key soft-touch keyboard, triple 5-digit display (one of which is 2-color), and two bar graphs with configurable function. Controls and commands can be sent from the front panel or via 4 digital inputs that can be assigned functions such as reset, calibration, man/auto, loc/rem, hold, raise/lower (motopotentiometer function), parameter set selection, setpoint selection. The instrument has 4 configurable relay outputs as standard. More extended configurations are available with the following options: 
- isolated analog output for retransmission of process, peak, remote set, deviation, alarm setpoint, differential values
- expansion with 4 I/O 
- communication interface Modbus RTU 
- communication interface Profibus DP (slave) 

CONTROLLER 
Self-adapting PI control or double-action PID (heating/cooling), ratio controller, differential pressure controller, selftuning, continuous or one-shot autotuning, Auto/man, Loc/rem, setpoint gradient, power gradient, dynamic power limits. 8 sets of selectable PID parameters based on setpoint level / PV / deviation or from digital inputs. 

ALARMS 
4 completely configurable alarm setpoints. 
Selectable “failsafe” function. 

MATH FUNCTIONS 
The 2500 controller lets you define two distinct math relations between two analog inputs. The results can be freely used as setpoints, alarm setpoints, control output, etc... 

DIGITAL COMMUNICATION 
The instrument offers an optional RS485 2/4 wire / RS232 serial interface with MODBUS RTU protocol for access to instrument parameters. 

CONFIGURATION 
The programming procedure is facilitated by the menu structure, with various configuration levels for quick and simple data search.
