🔧 Application
The VT-VSPA2-1-20/V0/T5 is intended for proportional hydraulic control applications. Compatible valve families include Rexroth 4WRA6, 4WRA10, 4WRZ, and 3DREP6 series valves, subject to the specific valve and system configuration.
Typical applications include hydraulic presses, machine tools, industrial production equipment, injection machinery, material-handling systems, and automated hydraulic positioning equipment.
🔌 System Integration
The module uses analog command-value signals to control compatible proportional valves. Its 24 V DC supply and selectable voltage/current command inputs allow integration with industrial controllers and hydraulic control systems.
The T5 option provides five ramp times for applications where controlled acceleration and deceleration of the valve command are required. Before installation, verify the valve type, electrical connection, command signal configuration, card holder, and existing hydraulic control circuit.
