Description:

Libratherm offers Microcontroller based multiple Ramp / Soak programmable PID temperature controller Model PRC-489 which is designed to improve reliability, accuracy and control for all temperature control applications. It features Ramp and Soak functions (the capability to control the temperature and its rate of change over a predetermined time span). Single pattern of total 16 (ramp/soak) steps can be programmed and stored in the memory. It can also be used as single set point control when the ramp/soak profile control is not desired.

PRC-489 offers both switching outputs in the form of SSR driver/Triac (AC SSR) for external SSR or external load contactor and analog output in the form of (4-20) mA or (0-5) volt control signal, which can be used to control heater power through external Thyristor power regulator. The analog outputs can be directly connected to Libratherm make single phase / three phase SCR based phase angle or zero cross over fired power regulators.

Additional one/two relays are also provided for time or temperature dependent event outputs as per the system requirement. The programmed profile and other parameters are retained in the nonvolatile memory in the event of power failure. In case of thermocouple break, the control can be transferred to manual mode to continue the heating cycle and user can alter the % of control output. The deviation hold feature assures guaranteed ramp. For quick heating from ambient temperature the hold feature is disabled in the very 1st ramp. Front Panel LED indicates start and end of the cycle, the status of heater output, status of heating ramp, soaking or cooling ramp. The unit of temperature measurement can also be selected as oC or oF as desired.

Features:
  • Accepts standard type of thermocouple, RTD, Voltage or Current signal.
  • Control output of Relay / TRAIC / DC pulse / (4-20)mA / (0-5)Volt.
  • Servo start from the current process temperature.
  • 1 to 16 programmable ramp/soak steps with rate programming facility.
  • Master / Slave concept with 1 master and max. 30 slaves.
  • Each controller can be configured as master or slave with 1 master and many slaves.
  • Can be used as single set point control with online set point change facility.

Applications:
  • Furnace / oven control
  • PWHT and SR heat treatment cycle
