The Rexroth VT 11015-11 is a high-performance analog amplifier card in Eurocard format, specifically engineered for controlling proportional valves without electrical position feedback. It provides precise and reliable command signal processing, featuring a differential amplifier input, an adjustable ramp generator for smooth acceleration and deceleration, and two pulse-width modulated (PWM) output stages. The card includes status LEDs for quick diagnostics and potentiometers for fine-tuning parameters like ramp times and command value attenuation. Its robust design and compliance with ESD/EMC standards make it an ideal solution for demanding industrial hydraulic applications requiring accurate valve control.
