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.

Description:
Libratherm offers high quality and low cost, versatile microcontroller based Temperature/Process controller model DTC-903. It is designed to suit general purpose industrial temperature and process control applications for precise and accurate measurement and control. DTC-903 offers the facility to use it as heating control in on-off or Time proportional P + I mode and cooling control in On-Off mode.
DTC-903 accepts user selectable inputs from J or K type thermocouple or RTD (Pt-100) sensors or linear signal of 4-20mA. Being microcontroller based 1oC or 0.1oC indicating accuracy is achieved by software linearization technique, where non- linear nature of thermocouple and RTD sensors is linearized for accurate indication. User can select the desired range of Pt-100 inputs.
Two independent set points are programmable over the full range of the selected input. Each set point can also be configured for High Alarm (Internal relay turns ON when actual temperature value exceeds the set point), Low Alarm (Internal relay turns ON when actual temperature value is below the set point), Deviation Alarm (whenever the process value is outside the band, the relay turns ON) and OFF state (Where relays will not turn ON under any condition). The control outputs are optically isolated in the form of DC pulse, AC SSR (Triac) or electromechanical relays. Retransmission output of 4-20mA proportional to the process value is available as additional features. Whenever control action is not desired, user can configure DTC-903 as indicator only.
