Overview
Rexroth VT5003-42/R1E Electronic Amplifier Module
The Rexroth VT5003-42/R1E is a proportional electronic amplifier module from the VT5000 series, engineered for industrial motion control and proportional valve actuation. This Eurocard-format module amplifies low-level control signals for hydraulic and pneumatic proportional directional control valves (DBETR series). Originally manufactured by Mannesmann Rexroth (now Bosch Rexroth), it remains a reliable choice for legacy system maintenance and retrofit applications where compatible VT5000-series hardware is in use.
Key Features
- 24 VDC input power supply
- 2.2 ampere output capacity
- Eurocard (160 × 100 mm) form factor for standard rack mounting
- 1-second ramp time for smooth proportional response
- Proportional amplifier design suitable for DBETR solenoid control
- Discontinued by manufacturer; available as used surplus stock
Technical Specifications
Note: Specifications verified from distributor documentation. Consult original Rexroth datasheets for complete electrical and environmental ratings.
