PID-8000 – 4/6/8 loop PID Controller for heating and cooling control.
Libratherm offers ARM Processor-based one to eight loop PID Temperature Controller (Model PID-8000) for processes requiring multiple zones of heating or heating plus cooling control. It is most suitable for the difficult process, which results in frequent system disturbances, and applications where simultaneous and accurate temperature control of a number of heating/cooling zone is required. It also eliminates the need for a number of individual PID or ON/OFF Temperature Controllers thereby saves on cost. PID-8000 can accept max 8 similar type of Thermocouples or RTD (Pt-100) inputs and can provide switching PID or ON/OFF 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 are also displayed with the respective Zone No. Each zone loop parameter like PID, SET, Hysteresis, Power Limit, and Ramp Time values can be independently 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 40mS. It also provides common High and Low alarm relay outputs, which can be used for external temperature-dependent, inter-locking, or audio-visual alarms. In brief, PID-8000 is as good as 8 independent PID controllers in a single enclosure, with the facility of different input per channel, different setpoint per channel, and different output per channel – a unique feature.
One of the serial interface RS-485 ports in Modbus protocol is available for the computer interface. The supporting window-based software allows the user to monitor the behavior of all the heating zones in both graphical and tabular form on a computer screen. 2nd RS485 port can be used for Master / Slave functions to cascade more than 1 and a maximum of 30 PID-8000 with each other.
Libratherm also supplies complete ready to use Temperature Control Panel using PID-8000 and other switchgear items and power controllers, which finds its applications in large heating systems having a number of sensors or number of heaters such as Plastic Extruders manufacturing pipes, sheets, etc, Plastic Injection for runner less molding, Tunnel Furnaces for annealing, large Ovens and similar heating systems for industrial use.
