The Bosch Rexroth VT-VRRA 1-527-20/V0/2STV Valve Amplifier (Material Number 0811405063) is a sophisticated control device designed to manage valves with precision and efficiency. This particular model is engineered for compatibility with Bosch's type 4WRL10 and 3WRCB25 valves, ensuring a seamless integration for users needing reliable valve control solutions. The valve amplifier boasts a command value input ranging from 0 to 10 volts, which allows for flexible and precise input signal management. Equipped with a controlled output stage, the VT-VRRA 1-527-20/V0/2STV ensures closed-loop position control utilizing PID characteristics that contribute to its accuracy and responsiveness. The device's fast energization and deletion capabilities enable short actuating times, critical for applications requiring quick response times. Safety features are integral to the design of this valve amplifier, including an enable input that provides an additional layer of operational security. The outputs are short-circuit-proof, protecting the device from potential electrical faults. To enhance calibration precision, the zero point is adjustable, allowing users to fine-tune the system according to their specific requirements. Another notable feature is the cable break detection for the actual value cable. This function ensures that any disruption in connectivity is promptly identified, preventing errors due to signal loss. The component series 2X denotes the series version of this amplifier, indicating its place within Bosch's product line-up and compatibility with other components in the series. Overall, the Bosch VT-VRRA 1-527-20/V0/2STV Valve Amplifier represents a reliable option for those in need of high-performance valve control with robust safety features and quick installation procedures.

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 or b14 or z28 must be separately led to the central ground (neutral point).
