Proportional Card for Hydraulic Systems (Industrial Use) Proportional Card – Precision Control for Hydraulic Amplification Our Proportional Card is the brain behind precise hydraulic control, especially when integrated with amplifier boards and proportional valves. Designed to convert input signals into smooth, regulated outputs, this card ensures optimal performance in applications requiring variable pressure, speed, or flow—such as injection molding machines, die casting, presses, and other industrial automation systems. Key Features: Accurate signal conversion (0–10V / 4–20mA) Seamless integration with proportional valves and amplifier boards Compact, durable design with industrial-grade components Overload, short-circuit, and reverse polarity protection Adjustable gain, ramp, and offset for precise control Engineered for high responsiveness and stability, the proportional card improves energy efficiency and machine life by reducing jerky movements and system pressure spikes. Whether used in hydraulic power packs or advanced motion control systems, it’s a reliable tool for achieving consistent, high-precision performance.
