Abstract

A multiple zone temperature controller for a hot runner injection molding system. The temperature controller includes inputs for signals from two or more thermocouples corresponding to two or more heating zones. The thermocouple inputs are time-division multiplexed and the output is amplified and input to a microcontroller. The microcontroller manages and controls operation of power switching stages for controlling the power supplied to heating elements corresponding to each of the heating zones. The multiplexer is a low impedance switch.
