Description

Overview

The Rexroth VT5003S31R1 is a proportional valve amplifier module designed to drive proportional solenoid-operated directional control valves in hydraulic systems. This compact amplifier delivers proportional solenoid current with integrated ramp control, enabling smooth acceleration and deceleration of hydraulic loads. The VT5003 series is widely used in mobile equipment, industrial presses, injection molding systems, and automation machinery where precise proportional valve control is critical.

Key Features

• Proportional solenoid current output with command value 0–10 V input
• Integrated ramp generator for smooth load transitions and reduced shock loading
• Compact plug-in amplifier card design for easy installation and replacement
• Low noise operation and high-resolution control response
• Compatible with standard proportional directional control valves

Technical Specifications

• Amplifier Type: Proportional solenoid driver with ramp control
• Input Signal: 0–10 V DC command signal
• Output: Proportional solenoid current (valve-dependent)
• Ramp Function: Adjustable up and down ramps for smooth transitions
• Form Factor: Plug-in amplifier card module
• Mounting: Cavity or panel mount (verify with your installation configuration)
• Control Interface: Proportional voltage input with response monitoring
• Manufacturer: Bosch Rexroth AG (formerly Mannesmann Rexroth)
• Condition: Used, fully functional

Typical Applications

• Mobile equipment (excavators, loaders, graders) proportional valve actuation
• Industrial hydraulic presses and molding systems
• Proportional directional control valve driving
• Load-sensing and pressure-compensated hydraulic circuits
• Automation machinery requiring smooth proportional control
• Retrofit and replacement applications in legacy systems

Compatibility & ReplacementsCompatible With

• Proportional directional control valves (4/3 and 3/2 spool types)
• Standard 24 VDC solenoid-operated proportional valves
• Rexroth VT 5000 series proportional valve control systems
• Hydraulic systems with 0–10 V proportional command signals

Replaces / Drop-In Replacement For

The VT5003S31R1 may replace earlier VT 5003 series amplifiers. Verify your original part number format (hyphens may vary: VT5003-S-31-R1, VT 5003 S31 R1, or VT5003S31R1) and compatibility with your system integrator before ordering. Do not assume interchangeability with other VT series amplifiers without technical documentation review.

Works With

• Proportional hydraulic solenoid valve packages
• Integrated control modules and PLC systems with analog output
• Ramp control and load-limiting circuit configurations
• Standard industrial 24 VDC proportional valve electronics
