Product Description
VT-VSPA Series Proportional Amplifier Cards (Rexroth/Mannesmann)
Product Overview: The VT-VSPA series consists of analog amplifier cards designed to drive proportional valves without electrical position feedback. These controllers convert standard analog command values (such as 0-10V or 4-20mA) into precision Pulse Width Modulated (PWM) current for proportional solenoids. Widely utilized in power plants, metallurgy, and heavy hydraulic systems, the VT-VSPA cards ensure smooth switching and pressure regulation through integrated step functions and ramp generators.
Featured models include: VT-VSPA2-1-11/T1, VT-VSPA2-1-2X/V0/T1, and compatible variants like VT-VSPA1-1-1X (Replacement for VT-MSPA1-2X/A5/000/000).
Key Technical Advantages:
Precision Current Regulation: Features closed-loop current control to automatically compensate for coil resistance changes due to temperature, ensuring consistent force/flow output.
Versatile Adjustment: The cards integrate potentiometers for Ramp times, Zero point, and Gain, allowing fine-tuning for specific valve characteristics.
Seamless Upgrade Path: The legacy VT-MSPA1 series is now replaced by the advanced VT-VSPA1 series, offering identical Euro-card interfaces for plug-and-play upgrades.
Industrial Durability: Designed in the classic Euro-card format for standard 19-inch racks, providing excellent Electromagnetic Compatibility (EMC) in harsh environments.
