Dual loop controller

Thanks to the universal measuring inputs, it can be used for controlling of temperature and other physical values (e.g. pressure, humidity). Every user can update controller's software individually, thus getting access to the additional features added by the LUMEL development team.

MODERN CONTROL FUNCTIONS

• independent dual loop
• PID, on/off, three-step control of heating-cooling and step-by-step control
• innovative SMART PID algorithm with auto-tuning function (automatic selection of PID parameters)
• the source of control signal is one of the two inputs or the sum/difference of the signal from two inputs combined
• 4 sets of PID parameters and additional set for cooling (for each channel)
• 6 types of alarm with programmable hysteresis and memory (latch function)
• gain Scheduling feature - automatic PID set switching, depending on the set temperature (when the object behaves decidedly differently in various temperatures)
• digital communication - RS485 (standard), Ethernet (option)

• process  parameter  logging  on SD card (.csv files)
• ftp server
• web  server (to download the .csv archive files remotely)
•  

• 3.5" full-colour graphic screen with luminosity control
• menu available in Polish and English
• password-protected regulator access (4 users, 3 access levels)
• signaling a state of binary inputs and two-state outputs

• 4 set point values switchable by the binary inputs (for each loop)
• soft-start function for set point values change, programmable increase/decrease
• also an additional input may serve as the source of set point value (input 3)

• 60 internal programs (30 programs per channel)
• 15 units per program
• signaling up to 6 events per unit (two-state outputs)
• selection of PID parameters for any unit
• iterations number setting (up to 9999 repetitions)
