The Rexroth VT2000-S-48/2 is a high-performance analog proportional amplifier designed in the standard Eurocard format. It is engineered for the precise control of single solenoid proportional valves that do not have electrical position feedback. This amplifier card provides stable and reliable performance in various industrial hydraulic systems. Key features include a differential input for command values, an adjustable ramp generator for smooth acceleration and deceleration, and adjustable bias and gain (sensitivity). The pulse-width modulated (PWM) output stage ensures efficient power management and accurate valve control, making it an ideal choice for applications requiring precise hydraulic regulation.
