The Bosch Rexroth VT-VRRA 1-527-20/V0 (0811405060) is a valve amplifier designed for precise control of Bosch's type 4WRPH6…L-2x proportional control valves. This component, which belongs to the series 2X, is tailored for applications requiring quick installation and efficient operation. It features a command value input ranging from 0 to 10 V, enabling seamless integration into various control systems. The unit boasts a controlled output stage with closed-loop position control incorporating PID characteristics, ensuring accurate and responsive valve actuation. This capability is further enhanced by the amplifier's fast energization and deletion functions, which contribute to short actuating times critical in dynamic systems. Safety and reliability are also core aspects of the VT-VRRA 1-527-20/V0's design. It includes an enable input for controlled operation, as well as short-circuit-proof outputs that protect against electrical malfunctions. Additionally, the zero point can be adjusted according to system requirements, offering flexibility during setup or maintenance procedures. Moreover, the device incorporates cable break detection specifically for the actual value cable, which adds an extra layer of monitoring to maintain system integrity. This feature helps in early identification of potential issues that could compromise performance or lead to downtime. Overall, the Bosch VT-VRRA 1-527-20/V0 valve amplifier is a robust and versatile component engineered to facilitate precise control of solenoid-operated valves with position feedback in demanding applications where rapid response and high reliability are paramount.

For applications outside these parameters, please consult us!
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).
