The Bosch Rexroth VT-VRPA 1-527-1X/V0/PV (0811405096) is a sophisticated hydraulic control valve designed for precision in closed-loop position control applications. It features a controlled output stage that integrates PID characteristics, ensuring responsive and accurate control over the positioning of hydraulic actuators. The fast energization and deletion capabilities of this valve contribute to its ability to achieve short actuating times, which is critical in dynamic systems requiring quick responses. Additionally, the VT-VRPA 1-527-1X/V0/PV comes with an enable input function that provides an extra layer of operational safety, allowing the system to activate the valve only when necessary. Its short-circuit-proof outputs are engineered to withstand electrical anomalies, ensuring reliability and longevity in harsh industrial environments. Fine-tuning is made possible with adjustable zero point and sensitivity settings, allowing users to calibrate the valve according to specific system requirements for optimal performance. The robust design and advanced features make this Bosch valve an essential component for applications demanding high levels of precision and speed in hydraulic control.

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.
