This set up is designed to study performance of analog PID controllerwith model process as temperature control system. The set up has builtin signal source as reference, digital voltmeter as temperature indicator,PID controller with saperate controls and a model process with built in regulated dc supply to operate the system.

The Selec TC518 is a sophisticated auto tuning PID controller or on/off controller with selectable thermocouple, RTD up to two outputs. Versions are available with different relay and SSR outputs. The controller can be configured as on/off or PID control and alarm outputs, or as 2 on/off or PID controls (heat/cool) plus 1 alarm output. It has a large dual 3 digit LED display to show the set point and the process value and is suitable for use with power supplies of 85 to 270 VAC   Features High performance Dual display, 4 digit, 7 segment LED LED status indicator: Relay ON, Tune 3 front panel control buttons TC / RTD inputs PID, ON/OFF control Single set point °C / °F selectable Control output: Relay or SSR drive

Libratherm offers Microprocessor based one to eight loop PID Temperature Controller (Model PID- 8000) for processes requiring multiple zones heating or heating plus cooling control. It is most suitable for difficult process, which results in frequent system disturbances, and applications where simultaneous and accurate temperature control of number of heatingcooling zone is required. It also eliminates the need for number of individual PID or ONOFF Temperature Controllers thereby saves on cost. PID-8000 can accept 8 similar type of Thermocouples or RTD (Pt-100) inputs and can provide switching PID or ONOFF Control output in the form of DC Pulses or SSR Drivers for heating and cooling. It can also simultaneously provide 8 analog PID control Outputs in the form of (4-20mA) or (0-5) volt, which can be used to drive external SCR Heater Power Controller or other actuators. Open or Faulty sensor indications for each zone is also displayed with the respective Zone No. Each zone loop parameters like PID, SET, Hysterisis, Power Limit and Ramp Time values can be independently programmed from the user-friendly front panel membrane keyboard. Features:  Microprocessor based design.  Elegant looks and Very easy to operate.  Accepts all types of maximum 8 inputs.  PID or ON Off heat and cool action per channel.  All zones are individually configurable for Heat or Cool.  Compact in size – ½ DIN (192 x 96 x 200 mm).
