The Hetronik HC500-VU2-D is a high-performance proportional valve amplifier card designed for precise control in demanding industrial applications. As a key component in the HC500 control system series, this module is widely used in injection molding machines and other hydraulic systems to regulate pressure and flow with exceptional accuracy. It processes analog setpoint signals and converts them into a controlled, pulse-width-modulated (PWM) output to drive proportional valve solenoids. This ensures stable, repeatable, and efficient machine operation, making it an essential part for maintaining and optimizing automated manufacturing processes.
