The Rexroth VT5041-25/3 is an analog amplifier card designed in Eurocard format for controlling proportional pressure valves without electrical position feedback. It is suitable for various Rexroth valve series such as DBE, ZDBE, DBEM, ZDBEM, DBET, DBETE, and 3DREP. This amplifier card provides precise control by converting an input voltage signal into a corresponding output current for the valve solenoid. It features adjustable ramp times (up/down), gain, and bias via potentiometers located on the front panel, allowing for fine-tuning to specific application requirements. The card includes a differential input stage and operates with a standard 24V DC supply voltage.
