Bosch Rexroth VT-MRPA2-1X and VT-MRPA1-1X Valve Amplifiers


Bosch Rexroth VT-MRPA2-1X and VT-MRPA1-1X amplifiers are used to control proportional directional valves with electrical position feedback. The step function ensures fast passing of the overlap while the position controller controls the control spool position. Two amplifier outputs supply current for the valve solenoids.

The 1X series valve amplifier has an analogue, modular design for valves with one or two solenoids: 4WRE 6–2X and 4WRE 10–2X.

Other features of the Bosch Rexroth VT-MRPA2-1X and VT-MRPA1-1X valve amplifiers include:

  • Differential input for voltage
  • Ramp generator with separately adjustable ramp times “up/down”
  • Adjustable zero point and sensitivity
  • Adjustable step level
  • Cable break detection for actual value cable
  • Reverse polarity protection for the operating voltage
  • LED displays for ready for operation and enable
