VT-VRPA1-52-10a/V0/0
The Bosch Rexroth Indramat VT-VRPA1-52-10a/V0/0 proportional valve amplifier is a robust member of the VT-VRPA Electric Amplifiers family, designed for precise control of servo solenoid valves in demanding industrial automation applications. It delivers closed-loop position control with a PID controller, ensuring stable and accurate valve positioning under varying load conditions. Featuring automatic quadrant recognition, the amplifier detects transitions between operational quadrants seamlessly, maintaining smooth directional changes. The unit supports position transducer feedback from 0 to ±10 V, providing high-resolution input for real-time control. Built to Eurocard format for 19″ rack installation, it integrates easily into modular control cabinets and centralized automation racks.
The VT-VRPA1-52-10a/V0/0’s technical specifications include a three-phase input rated at 230 V at 50/60 Hz, delivering up to 3 HP of rated power to connected solenoid valves. It operates with clocked current regulation on its solenoid output, optimizing response time and energy efficiency. The amplifier implements closed-loop position control with PID controller as its primary control type and features LED indicators for fault monitoring under its fault detection specification. It accommodates position transducer feedback (0 to ±10 V) and offers automatic quadrant recognition to detect quadrant transitions. Mounting is via Eurocard format for 19″ rack installation, and it is expressly compatible with 4WRL…M-3X series proportional valves. Classified as a frequency inverter drive, it belongs to the 2X (Series 20 to 29) lineup by Bosch Rexroth Indramat.
Operational performance of the amplifier is optimized for industrial environments: its three-phase design supports high dynamic loads, while the clocked current regulation reduces thermal stress on solenoid coils. Cable management guidelines specify 1.5 mm² conductors for runs up to 20 m and 2.5 mm² for runs between 20 m and 60 m to minimize signal interference. Transducer wiring requires 4 x 0.5 mm² shielded cable for accurate position feedback and noise rejection. The integrated PID processor adjusts output continuously to maintain setpoints, and instantaneous fault detection via LEDs enables rapid diagnostics. Its frequency range of 50/60 Hz and three-phase configuration ensure compatibility with standard industrial power systems.
System integration is streamlined by its Eurocard design and rack compatibility, simplifying installation in centralized control panels. The amplifier interfaces directly with Bosch Rexroth servo solenoid valves, eliminating the need for external converters or signal conditioners. Its comprehensive set of features and rugged construction make it ideal for machine tools, packaging equipment, hydraulic test stands, and process automation systems. With precise closed-loop control, built-in diagnostics, and automatic quadrant recognition, the VT-VRPA1-52-10a/V0/0 delivers the reliability and performance essential for modern industrial automation.
