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
