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.

Features:

•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
