Product Overview

The VT-VSPD-1-23/V0/0-0-1 is a Rexroth analog proportional servo valve amplifier card belonging to the VT series modular drive controllers, specially designed for driving 4-way closed-loop electro-hydraulic servo valves integrated with LVDT spool position sensors. It receives ±10V analog setpoint command signals from PLC, motion controller or joystick operators, executes high-speed PID closed-loop calculation based on real-time LVDT spool feedback, and outputs proportional drive current to accurately adjust the valve spool opening and flow direction.
