Description
The Rexroth VT TSPD-1-10/V0/0 and the associated VT-SWKD-1-13C/V0/0 are high-precision Digital Valve Amplifier PCB cards designed for the control of proportional hydraulic valves with electrical position feedback. These modules translate low-level command signals (typically \pm 10V or 4–20mA) into high-current Pulse Width Modulation (PWM) signals to drive the solenoid actuators of proportional directional or pressure valves.
The VT TSPD series is widely utilized in industrial hydraulics where precise positioning, acceleration, and deceleration profiles are required. These cards ensure high dynamic response and repeatability, critical for applications like injection molding machines, turbine control, and heavy-duty press systems.

Important Technical Note: These digital amplifiers are parameter-driven. If you are replacing a card, the new module will likely require a “Parameter Download” using the Rexroth BODAC software. Without the correct configuration file—which contains the valve-specific gain, dither frequency, and offset values—the valve will not function accurately and could result in unstable control or “hunting” of the spool position.
