Description of 5 digit PID Temperature Controller PID-967:
Libratherm offers 5 digit PID controller model PID-967, which is designed and developed using the latest high speed 8 bit microcontroller chip incorporating 16 bit ADC and 12 bit DAC and programmed with the time tested and field proven PID algorithm. PID controllers are 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 which are required to control the complex system.
PID-967 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 analog output of 4-20mA,0-5V or 0-10VDC to drive external thyristor based power regulators.
Features:
Microcontroller based design.
5 digit display with resolution of 0.1oC for high temperature measurement
User selectable input type T/C,RTD, 4-20mA, 0-10VDC
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.
RS485 digital interface for PC connectivity
Resolution | 1 °C /0.1 °C for thermocouples and 0.1oC for Pt-100. For V and mA inputs the display resolution is subject to the required range. For V and mA input the position of the decimal point can be selected. |
