Libratherm offers 2 to 16 zone control panel for hot runner temperature control system,widely used in plastic injection moulding. The panels are designed taking into consideration all the required controlling and safety features to accurately maintain the desired temperature of all the zones.. The main components of the control panel are listed below.
1) PID temperature controller model PID-723 : This controller accepts the input from either K type or J type thermocouple or from RTD (Pt-100) sensor. The control output is in the form of DC pulse to drive external solid state relay or in the form of 4-20mA/0-5V signal to drive phase angle control SCR power regulator (model LTC-16). The built in Power limit and Ramp time features allows the gradual heating to evaporate the moisture content in the heaters. The ramp heating can be achieved by opting for the SCR control instead of SSR control. The controller has dual display, the upper display shows the heater temperature.
