Category: VT-VRPA1-1

The VT-VRPA1-100 proportional amplifier controls the DBETR proportional relief valves with position feedback. The user may confugure the analog input and extend ramp times.


•Analog amplifiers in Eurocard format
•Voltage stabilization, partially with raised measuring zero point
•Differential input – 0–10 V/0–20 mA/4–20 mA
•Ramp generator that can be switched off
•Oscillator/demodulator for electrical position feedback
•PID-controller for controlling the control spool position
•able break detection with LED indicator lamp for position transducer; in the event of a cable break, the output amplifier is de-energized
•Enable input
