The Rexroth VT 11118-11 is a high-performance analog amplifier card designed in the standard Eurocard format. It is engineered for the precise control of proportional pressure valves that operate without electrical position feedback, such as the DBET, DBE, 3DREP 6, and ZDRE series. This amplifier card features a differential input, allowing for either voltage or current command signals, and provides a pulse-width modulated (PWM) output to the valve solenoid. The card includes adjustable potentiometers for zero point, sensitivity, and ramp times (up/down), enabling fine-tuning for optimal system performance and stability. Its robust design makes it a reliable component for demanding industrial hydraulic applications.
