The Rexroth VT5005-S16-R5 is a high-performance proportional amplifier designed in a standard Euro-card format for seamless integration into control racks. It is engineered to provide precise, open-loop control for proportional valves with two solenoids that do not have electrical position feedback. This amplifier card converts a command value signal (voltage or current) into a regulated output current to drive the valve solenoids. Key features include an integrated ramp generator with separately adjustable ramp times for smooth operation, ensuring stable and reliable performance in demanding industrial hydraulic applications.
