PRC-8000-44 input and 4 zone Ramp / Soak Programmable Profile PID Temperature Controller
PRC-8000-66 input and 6 zone Ramp / Soak Programmable Profile PID Temperature Controller
PRC-8000-88 input and 8 zone Ramp / Soak Programmable Profile PID Temperature Controller

Description:
Libratherm offers Microprocessor based Eight Zone PID Temperature indicator / Controller (Model PRC-8000) for accurate temperature control of multiple zone Gradual Heating and Cooling is required. PRC 8000 is ideally suitable and is most economical as it eliminates the need for number of individual PID or ON/OFF Temperature Controllers required per zone. Each zone can be independently programmed for 16 steps of Ramp/Soak profile. Each loop parameters like PID, Hysteresis, Deviation Hold, Facility to skip unused channel etc… can be programmed from the user-friendly front panel membrane keyboard. The programmed profile and other parameters are retained in the non-volatile memory in the event of power failure.

PRC 8000 can accept 8 Thermocouples or RTD(Pt-100)3 wire inputs and can provide switching PID or ON/OFF Control output in the form of DC Pulses or SSR or relay to drive external load contactor drivers for heating and cooling. It can simultaneously provide 8 analog PID control outputs in the form of (4-20)mA or (0-5)volt, which can be used to control heater power through Thyristor power pack (for electrical heating system) or to control the position of a modulating motor valve (for oil or gas fired heating systems). The analog outputs can be directly connected to Libratherm make single phase / three phase SCR phase angle fired power controller which is ideally suitable for both resistive and inductive heating load

With the facility of copying Ramp/Soak profiles parameters of the single zone temperature controller to the all other available zones. Based on eight zone temperature controller is programed for Temperature Controller.

Features:
  • Microprocessor based design.
  • Eight zone - independent, uniform or average control
  • Highly accurate and sturdy in operation.
  • Accuracy better than ± 0.1 % of the full scale.
  • Accepts standard type of thermocouple or RTD(Pt-100)/2 or 3-wire input.
  • Control output of Relay or TRAIC or DC pulse or (4-20)mA or (0-5)Volt or any other.
  • Servo start from the process temperature
  • Deviation hold back facility (common or individual)
  • Copying facility
  • Facility to use as PID and / or ON / Off controller
  • Hardware security locks for unauthorized tempering of the set values.
  • 3 separate displays to display channel no, process temp. & Set temp.
  • (Extra 6 digit display for real time clock – for PC/Printer interface)
  • Models with 2, 4, 6 & 8 inputs are available.
  • 1 to 16 Ramp / Soak steps individually programmable per zone.

Application:
  • Heat Treatment
  • Large ovens and furnace with multiple sensors
  • Environmental Chambers
  • Multi zone Stress relieving furnace
  • Pre and Post welding heat treatment
  • Tunnel furnace
  • Normalizing furnace
