The Rexroth R900942541 VT-SWMA-1-10a/V0/0 is a high-performance analog controller designed for precise regulation of swivel angle, pressure, and power in A4VSO series axial piston variable displacement pumps with HS5 electrical control. Housed in a standard Eurocard format, this amplifier card is ideal for rack mounting in industrial control cabinets. It features a differential amplifier input for command values, actual value inputs for feedback, and a controlled output stage with a dither signal to drive the pump’s proportional solenoid. This ensures optimal performance, stability, and accuracy in demanding hydraulic applications.
