Product Profile of Analog Amplifiers With Electrical Position Feedback
Rexroth is a drive & control company offering drive and control technologies, both specialized and integrated. Rexroth is a wholly-owned subsidiary of robert bosch gmbh. The analog amplifiers in eurocard format for proportional valves with electrical position feedback have the following salient features:
- Analog amplifiers in eurocard format
- Voltage stabilization, partially with raised measuring zero point, filter capacitor on the amplifier card
- Ramp generator that can be switched off
- Step function for quickly passing through overlaps of directional valves
- Oscillator/demodulator for inductive position feedback
- Pid-controller for controlling the control spool position
- Cable break detection with led indicator lamp for position transducer; in the event of a cable break, the output amplifier is de-energized
- Clocked output amplifier with current regulation
