Bosch Rexroth Valve Amplifier for Proportional Directional Valve With Electrical Position Feedback – VT-MRPA2 and VT-MRPA1
Bosch Rexroth VT-MRPA2 and VT-MRPA1 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 valve amplifier include:
- Command value input (differential input);
- Enable input;
- Input for electrical position feedback;
- Adjustable ramp time, step level and maximum solenoid current;
- LED display for ready for operation and enable;
- Top hat rail mounting.
