Microprocessor Based Multi-zone Ramp Controller

With our in-depth knowledge in this domain, we are definitely engaged in exporting and manufacturing and supplying of the Microprocessor Based Multi-zone Ramp Controller in Mumbai, Maharashtra, India. It offers Microprocessor centered Eight Zone PID Temperature indicator / Controller (Model PRC-8000) for accurate temperature control of multiple zone Gradual Heating and Cooling is needed. 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 variables 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).
Its Features are:
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.
