Product Description
Rexroth VTS0234-46/AP025 (Part No.R900881344) is a Bosch Rexroth VTS series Eurocard proportional valve amplifier. It adopts standard Eurocard board structure to drive electro-hydraulic proportional valves and servo valves with position feedback. The board integrates closed-loop control circuit, accepts ±10V analog command signal and outputs PWM drive current to proportional valve solenoids. It supports ramp generation, offset/gain adjustment and fault monitoring. The PCB is coated with conformal coating with excellent vibration resistance and anti-interference performance, serving as the core spare part for electro-hydraulic control systems.
