Rexroth Driver Module VT-VRRA1-527-20/V0 Green Easy Integration High Reliability

Product Specification

Description:

The Rexroth Driver Module VT-VRRA1-527-20/V0 is a high-performance valve amplifier produced by Bosch Rexroth for precise control of proportional valves. The module belongs to the analog Euro-card format and is suitable for the control of high-frequency valves. The main function of the module is to amplify a weak input signal to drive a load (e.g. a hydraulic valve). It is equipped with controllable output stage, selective input, anti-short circuit output, and zero position adjustment. In addition, VT-VRRA1-527-20/V0 is equipped with actual value cable disconnection detection and position control function with PID characteristics, which can effectively improve the reliability and control accuracy of the system.
 

Application areas:

Industrial automation: The VT-VRRA1-527-20/V0 is widely used in various industrial automation scenarios, such as machine building, automotive production, aerospace, etc., to control proportional valves in hydraulic systems.
Hydraulic systems: The module is particularly suitable for hydraulic control systems that require high precision and fast response, such as injection molding machines, die casting machines and automated assembly lines.
Robotics: In robot joint control, the VT-VRRA1-527-20/V0 precisely controls the movement of hydraulic cylinders or motors to realize complex actions.
Test and Measurement Equipment: For precise control of hydraulic loads in test benches and experimental equipment.
Energy and power systems: In the energy sector, such as wind power and solar tracking systems, the module can be used to control the position of hydraulic cylinders.
 

Advantages:

High-precision control: The VT-VRRA1-527-20/V0 is equipped with a PID regulation function that enables high-precision closed-loop position control. The zero adjustment function allows the user to adjust the zero point of the valve as needed to improve control accuracy.
Fast Response: Designed for high-frequency ringing valves, the module is able to respond quickly to input signals and realize fast power-on and power-off.
The short start-up time and fast power-off features allow for excellent performance in dynamic control applications.
High Reliability: The disconnection detection function of the actual value cable effectively prevents system loss of control due to cable failure. The short-circuit-proof output design further enhances system safety and reliability.
Easy Integration: The module is available in a European standard card format for mounting in 19-inch racks for easy integration into existing control systems. A variety of connection options are available, including DIN 41612 plugs for easy connection to other equipment.
Adaptable: Operating temperature range of 0°C to +70°C and storage temperature range of -20°C to +70°C for a wide range of environmental conditions. Supports a wide range of supply voltages (21V to 40V) to adapt to different power supply environments.
User-friendly: Front panel is equipped with LED indicators to show module status (e.g. enabled, cable disconnected, undervoltage, etc.) for quick diagnosis of problems. Zero adjustment is realized by trimming potentiometers for easy operation.
Strong compatibility: VT-VRRA1-527-20/V0 is compatible with a variety of Bosch Rexroth high-frequency valves, such as the 4WRPH6...L-2x series proportional valves, which are able to meet the needs of different application scenarios.
