The Bosch Rexroth VT-VRPA1-527-1X/V0/QV-RTP (0811405103) is a sophisticated control valve designed for precise closed-loop position control with PID characteristics, ensuring high accuracy and dynamic response in various applications. This model features a controlled output stage that allows for rapid energization and deletion, resulting in exceptionally short actuating times suitable for systems requiring quick responses. Equipped with an enable input, the valve ensures safe operation by allowing the system to activate the valve only when necessary. Its short-circuit-proof outputs add an extra layer of protection against electrical faults, enhancing its reliability and longevity in demanding environments. The adjustable ramp time, sensitivity, and zero point provide users with the flexibility to fine-tune the valve's performance according to specific requirements. These adjustments can be critical in achieving optimal system efficiency and precision. Moreover, the Bosch VT-VRPA1-527-1X/V0/QV-RTP includes cable break detection for the actual value cable, a feature that promptly alerts users to any disruptions or failures in signal transmission. This immediate detection helps prevent potential inaccuracies or downtime due to cable issues. Overall, this model is engineered to offer robust performance and precise control in applications where fast actuation and high reliability are paramount. Its advanced features ensure it can be tailored to meet the nuanced demands of specialized systems without compromising on safety or quality.

Dimensions in mm
Dimensions in mm
The amplifier card may only be unplugged and plugged when de-energized.
The distance to aerial lines, radios, and radar systems has to be at least 1 m.
Do not lay solenoid and signal lines near power cables.
For signal lines and solenoid conductors, we recommend using shielded cables.
The cable shield must be connected to the control cabinet extensively and as short as possible.
The valve solenoid must not be connected to free-wheeling diodes or other protection circuits.
The cable lengths and cross-sections specified in the technical data must be complied with.
Wiring information
Power zero b2 and control zero b12 are to be bridged.
If the power supply unit is < 1 m away, directly to DIN connector.
In case of distances > 1 m, lead the control zero separately to the ground.
Information on ramp use
Ramp ON: No signal at b20.
Ramp OFF: 8.5...40 V at b20 or connection between b22 and b20.
In case of ramp OFF or cable break, any ramp started before will be canceled. Transition to the signal end value is realized in one step.
