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
Differential input
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
