Contact SupplierLibratherm offers Microprocessor based Eight Zone PID Temperature Controller (Model PID-8000) (AS GOOD AS EIGHT PID CONTROLLERS IN A SINGLE UNIT) for processes requiring multiple zone heating or heating plus cooling control. It is most suitable for difficult processes which results in frequent system disturbances, and applications where accurate and simultaneous 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 and panel space. It can accept 8 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 programmed from the user-friendly front panel membrane keyboard. The display scan rate is programmable from 1 to 99 seconds, whereas the internal control scanning is at the rate of 100mS. It also provides common High and Low alarm relay outputs which can be used for external temperature dependent inter locking or audiovisual alarm.
PID-8000 is available in standard 12 DIN (192 x 96 x 200mm) for 8 zones, 6 zones or 4 zones. It operates on 230 VAC with built in high and low supply voltage trip circuits. It is also protected against industrial RFIEMI Interference.
Libratherm also supplies complete Multizone Temperature Control Panel, which finds its applications in Plastic Extruders, Plastic Injection, Tunnel Furnaces, Ovens etc.
