Abstract: The present invention relates to injection mold hot runner control devices and more particularly to an injection molding control device which eliminates the conventional control cables to improve the quality of feedback signals received by the controller and the safety of the environment in which such systems are used. The present invention utilizes a signal processor to convert analog signals received from the mold temperature sensors into a digital feedback signal in the vicinity of the mold and to transmit such feedback signal to a receiver connected to a controller at a location remote from the mold. The mold controller processes the feedback signal and generates a corresponding control signal. The control signal is transmitted from the remotely located controller to the controlled device, typically the mold heaters.
