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).
