The Bosch Rexroth VT-VRPA 1-537-1X/V0/PV-RTP (0811405102) is a sophisticated electro-hydraulic amplifier designed for precise closed-loop position control with PID characteristics. It features a controlled output stage that ensures rapid energization and deletion, enabling short actuating times which are critical for responsive system performance. The device also includes an enable input function for enhanced operational safety and control. Equipped with short-circuit-proof outputs, the amplifier promises a reliable and secure operation even in the most demanding applications. Adjustability is also at the forefront of this product's capabilities, with users able to fine-tune both the zero point and sensitivity to match specific requirements, ensuring optimal performance and accuracy. The Bosch Rexroth VT-VRPA 1-537-1X/V0/PV-RTP is particularly suitable for use in applications where precise hydraulic control is necessary. Its fast response times make it ideal for systems that require quick reactions to control signals, while its robust construction ensures long-term reliability. Whether used in industrial automation or mobile hydraulics, this product delivers exceptional control fidelity and operational stability.

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.
