VT-MRPA2-2-11/V0/0
The VT-MRPA2-2-11/V0/0 from Bosch Rexroth Indramat belongs to the VT-VSPA Proportional Amplifiers series, delivering high-performance electronic valve control for industrial automation. This amplifier supports both ±10V command input and 4-20mA current input to drive proportional hydraulic valves with precision. It operates on a 400-480 VAC input voltage supply and features a maximum current limitation of 1.5A to protect downstream components. Housed in a robust IP20 enclosure, the unit is designed for reliability in a wide range of environments. Its modular, DIN-rail mountable design simplifies installation and maintenance in control cabinets.
The VT-MRPA2-2-11/V0/0 offers advanced technical capabilities to handle demanding hydraulic applications. It supports a three-phase power input delivering up to 5 kW of power output, ensuring ample drive capacity for single or dual solenoid valve configurations. The amplifier generates a PWM solenoid drive output with adjustable frequency to optimize valve response and energy efficiency. Comprehensive monitoring is enabled through built-in test jacks and integrated digital I/O for enable and status feedback signals, allowing real-time diagnostics without additional instrumentation. The combination of precise command interfaces and overcurrent protection guarantees stable, repeatable performance under varying loads.
Operationally, the amplifier excels in reliability and ease of use. Its modular, DIN-rail mountable architecture permits quick replacement and system expansion without rewiring. The IP20 enclosure provides dust protection while facilitating airflow around the unit, supported by an operating temperature range from –20°C to +50°C for consistent operation in harsh industrial conditions. The built-in test points streamline troubleshooting and reduce downtime, while the PWM control scheme minimizes heat generation and improves overall energy utilization. With support for both single and dual solenoid configurations, users gain flexibility in valve selection and hydraulic circuit design.
Integration of the VT-MRPA2-2-11/V0/0 into existing automation systems is straightforward due to its standardized command inputs and DIN-rail form factor. It is ideally suited for applications in mobile machinery, presses, injection molding, and general hydraulics where precise flow and pressure control are critical. The amplifier’s compatibility with Bosch Rexroth Indramat controllers enables seamless communication and parameterization within larger motion control networks. For engineers designing next-generation hydraulic systems, the VT-MRPA2-2-11/V0/0 delivers reliable, high-precision proportional valve control ready for immediate deployment.
