Description
Rexroth VT3000S34-R5
Technical Specifications
- Product Series: VT3000.
- Model: S34-R5.
- Output Current: 0-1.5A or 0-2.5A (adjustable).
- Input Signal: 0-10V or 4-20mA.
- Dither: Adjustable dither signal to reduce spool friction.
Functional Features
- Precise Current Control: Ensures accurate valve positioning.
- Adjustable Dither: Reduces hysteresis and improves valve response.
- Ramp Function: Integrated ramp generator for smooth actuator acceleration/deceleration.
- Diagnostic Output: Provides status signals for system monitoring.
Application Scenarios
Used in conjunction with Rexroth proportional valves for precise flow and pressure control in industrial hydraulics.
Performance Parameters
- Linearity: High linearity between input signal and output current.
- Temperature Stability: Minimal drift over operating temperature range.
Material Composition
Industrial-grade electronic components on a conformal-coated PCB. Robust plastic or metal housing.
Structural Characteristics
DIN rail or panel mount design. Front panel with adjustment potentiometers and status LEDs. Removable terminal blocks.
Working Principle
Receives a command signal and generates a proportional current with superimposed dither. This current drives the proportional solenoid, positioning the valve spool against a spring or feedback sensor.
Installation Requirements
Mount in a clean, dry location. Use shielded cables for input signals. Ensure proper grounding.
Usage Precautions
- Adjust dither and gain settings carefully to optimize valve performance.
- Verify input signal range matches amplifier configuration.
- Protect from excessive vibration and heat.
