Rexroth Driver Module VT-VRRA1-527-20/V0/2STV Green High Reliability Fast

Product Specification

Description:

Rexroth Driver Module VT-VRRA1-527-20/V0/2STV is a high-performance valve amplifier module produced by Bosch Rexroth. The module is an analog control type, adopting the European standard board format, and is specially designed for controlling pilot-operated directional control valves with electrical feedback. It realizes precise control of hydraulic valves by amplifying the input signal, ensuring the stability and response speed of the system operation.
The main technical parameters of the module are as follows:
Input signal: 0... ±10V.
Output current: maximum 2.7A.
Power supply voltage: nominal voltage 24V, range 21.... .40V.
Cable length: Coil cable up to 20m (1.5mm²), position sensor cable 4x0.5mm².
Control characteristics: Position control with PID characteristics to ensure high accuracy and fast response.
 

Areas of application:

Machine manufacturing: used in the hydraulic system of machine tools to realize high-precision motion control.
Automated production lines: to control the movement of hydraulic cylinders or motors in automated assembly lines.
Robotics: Precise signal amplification for the hydraulic drive of robot joints.
Aerospace: Hydraulic control systems for aircraft to ensure flight safety and operational precision.
Automotive manufacturing: In automotive production lines, hydraulic equipment is controlled for the assembly and testing of components.
Plastics processing: In injection molding machines, controlling hydraulic systems for precise mold opening and closing.
In addition, the module can be used in other hydraulic systems that require high dynamic response and precise control.
 

Advantages:

High-precision control: The use of PID control features enables high-precision position and velocity control. The zero position adjustment function ensures that the hydraulic valve is accurate in its initial position.
Fast Response: The module is equipped with fast power-on and power-off function, which can quickly respond to the control signal. It is suitable for high-frequency valves to ensure the dynamic performance of the system.
High reliability: The output stage has an anti-short-circuit protection function to extend the service life of the module. The disconnection detection function of actual value cable can effectively prevent the system abnormality caused by cable failure.
Strong flexibility: supports a variety of input signal ranges (0... ±10V), suitable for different control systems. Provides a variety of option configurations, such as 2STV and PO-IS, to meet the needs of different application scenarios.
Easy to integrate: The modules are in European standard board format, easy to install and integrate into existing systems. Detailed electrical connection and commissioning instructions are provided for quick deployment.
Energy saving and high efficiency: the module design is optimized for low power consumption and high efficiency. Suitable for a wide range of hydraulic valves, reducing the complexity of system design.
Easy maintenance: modular design for easy maintenance and replacement. Provide complete maintenance instructions and technical support.
