The Bosch Rexroth VT-SSPA1-508-2X/V0/0 (0811405144) is a valve amplifier designed for the precise control of proportional valves without electrical position feedback. This compact device facilitates quick assembly and commissioning, streamlining the integration process into various control systems. It is specifically engineered to operate with a single solenoid and is directly connected to the solenoid plug, ensuring a secure and efficient connection. The unit's functionality includes an LED indicator that confirms the presence of supply voltage, ensuring operational readiness. The command value input accepts a 0 to 10 V signal, allowing for fine-tuned control over pressure valves. Users can adjust critical settings such as zero point and sensitivity to match specific application requirements. Additionally, the amplifier features a differential input for enhanced signal integrity. For applications requiring gradual changes in valve position, an adjustable ramp function is available to modulate the command value smoothly over time. This feature is particularly useful in scenarios where sudden changes in valve position could be detrimental or where a soft start-up is required. Another customizable aspect of this valve amplifier is its dither frequency. Dithering helps prevent valve stiction and promotes more accurate positioning. While the dither amplitude comes preset from the factory at an optimal value for general use cases, it can be adjusted to accommodate special applications as needed. Operating on a 24 V power supply, this Bosch valve amplifier offers flexibility and precision in controlling proportional valves across various domains where reliable and accurate hydraulic or pneumatic control is essential. Its robust design and adjustable parameters make it suitable for a wide range of industrial applications that require meticulous valve operation without position feedback.
