PID Controller (Micro Controller Based)
PID Controller (Micro Controller Based)
Libratherm offers 5 digit PID controller, model PID-2003. It is designed and developed using the latest high speed micro controller chip and programmed with the time tested and field proven PID algorithm. PID controller is mainly used for the precise process control. Unlike On/Off type of oscillatory control, PID control action gives smooth and steady state control. This model offers, all the useful features required to control the complex system.
PID-2003 accepts universal single input. The control action is user selectable as PID or On/Off for both direct and reverse or heat and cool action. Control outputs are given in the form of optically isolated DC pulse to drive external SSR, Triac or AC SSR to operate AC operated load, electro mechanical relay and/or linear analogue output. The analogue output levels can also be configured for (4-20)mA or (0-5) / (0-10) volt using the front panel key board.
- Input -U (Universal): One analogue input - RTD(Pt-100)/ 2 or 3 wire and thermocouple (type J,K,R,S,B), 1-5V and 4-20 mA (i.e. maximum 8 user selectable inputs using keyboard and DIP switch on the back panel)
- Range: Full positive range of the selected input
- Decimal point: Programmable for voltage and current inputs.(0.1,0.01,0.001,0.0001)
- Output indications: Front panel LED indications for control output, alarms, control and A/M status and serial interface etc.
- Tuning: Auto/Manual tuning of PID values
- Memory backup: Retention of PID and set values in the built in non-volatile memory in case of power failure and automatic re-execution of control on power resumption.
- Loop supply: Isolated 18 to 24VDC @ 50 mA to power external two wire loop transmitter.
- Supply: (90VAC-250VAC), 50/60 Hz
- Size: 96 x 96 x 160 mm
- Micro controller based design
- Single loop PID function
- One Ramp/Soak feature (user programmable)
- Auto/Manual tuning of PID parameters
- Field proven algorithm tested successfully for various process control applications
