Product Description
0811405061 (Model VT-VRRA1-537-20/V0) is the analog high-response servo valve amplifier in Eurocard format from Bosch Rexroth, belonging to VT-VRRA1 series 2X version. It is designed for direct-operated high-response servo valves with LVDT position feedback (5WRP10 series). It accepts analog setpoint signals from upper-level control systems, integrates PID position closed-loop control and drives the servo valve solenoid. It provides short-circuit protection for output, enable control, valve zero adjustment and cable break detection for feedback signal. Standard Eurocard for 19-inch rack mounting, used for valve drive in electro-hydraulic servo systems.

Application
This amplifier is used for closed-loop electro-hydraulic servo control. It receives analog command from PLC/motion controller and drives 5WRP10 high-response servo valves to realize spool position closed-loop regulation. Widely applied in material testing machines, hydraulic fatigue test benches, metal forming presses, injection molding machines, aerospace hydraulic test benches and other high-precision electro-hydraulic equipment. It realizes force control, position control and high-frequency dynamic response processes to ensure fast, stable and high-precision response of hydraulic servo systems.
