Bosch Rexroth VT-MRPA1-100-11-V0-0 Valve Amplifier

The Bosch Rexroth Indramat VT-MRPA1-100-11/V0/0 is a modular valve amplifier card designed to drive proportional pressure valves with electrical position feedback, enabling precise closed-loop spool control in hydraulic control cabinets. It accepts a differential command value input of +10 V and is powered by a 24 V DC control supply, aligning with the VT-MRPA1 family’s analog control approach. The module emphasizes straightforward integration and service, with electrical feedback ensuring accurate valve response and repeatable performance for demanding hydraulic applications. The part number is R900779644, and the VT-MRPA1-100-11/V0/0 variant is documented in Rexroth Indramat catalogs as a valve amplifier for proportional valves, suitable for systems requiring proportional valve actuation and feedback, including pressure control and hydraulic position control in environments supporting valve operation up to the ratings of the connected hardware. Proportional valves driven by this amplifier can be used in circuits delivering pressures up to 315 bar, depending on the specific valve and system configuration.
