Category: VT-VRRA

The amplifier VT-VRRA1 controls standard servo solenoid valves with DC-LVDT feedback for direct operated 4WRPH..L-2X and 2-stage 4WRL..-3X. These are basic amplifiers. Since these components are normally used in closed loop applications, other features like ramp, time, and spool compenstion (jump) are not needed.

Features:


•Analog amplifiers in Eurocard format
•Controlled output stage
•Enable input
•Short-circuit-proof outputs
•Adjustment options: Valve zero point
•Cable break detection for actual value cable
•Closed-loop position control with PID characteristics
