The Bosch Rexroth VT-VRPA 1-527-1X/V0/PV-RTP (0811405101) is a sophisticated hydraulic amplifier designed for precise control in hydraulic systems. It features a closed-loop position control with PID characteristics, ensuring high accuracy and stability in the operation of hydraulic actuators. The device is engineered to provide fast energization and deletion, resulting in exceptionally short actuating times that are critical for dynamic system responses. Equipped with an enable input, the Bosch VT-VRPA 1-527-1X/V0/PV-RTP ensures safe operation by allowing the system to activate the output stage only when necessary. Its outputs are short-circuit-proof, providing additional protection against electrical faults and enhancing the reliability of the entire system. For customization and optimization of performance, this model offers adjustable ramp time, sensitivity, and zero point. These features allow for fine-tuning to match specific application requirements, ensuring optimal performance across a range of operating conditions. Moreover, the unit includes cable break detection for the actual value cable. This safety feature ensures immediate notification and response in case of wiring issues, preventing potential damage or failure in critical applications. Overall, the Bosch VT-VRPA 1-527-1X/V0/PV-RTP is designed to deliver precise control and fast response times in hydraulic systems while maintaining safety and reliability through its robust protection features.

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.
