The Rexroth VT2000-S-48/2 is an analog amplifier card designed for controlling proportional valves without electrical position feedback. Engineered in the standard Eurocard format, it is intended for installation in a 19-inch rack system. This amplifier provides precise control by converting an input command signal into a regulated output current for the proportional solenoid. Key features include an adjustable ramp generator for smooth acceleration and deceleration, a differential amplifier input, and a short-circuit-proof output stage. The VT2000-S-48/2 is a reliable and robust solution for open-loop control in various industrial hydraulic applications.
