Product Description:
The VT 11033-11b servo amplifier is produced by Bosch Rexroth Indramat as part of the VT Servo Amplifiers series. It converts a voltage reference from a motion controller into a regulated solenoid current for proportional hydraulic valves, allowing closed-loop adjustment of flow and pressure in automated presses, test rigs, and material-handling machinery. Its compact plug-in card format simplifies cabinet wiring and provides dedicated signal conditioning for one valve section.
Normal operation uses a 24 V DC supply, while the amplifier remains functional between a lower limit of 21.5 V and an upper limit of 35 V, providing tolerance for battery-backed or rectified sources. The control stage accepts a differential input spanning ±10 V, which suppresses ground loops and lets the PLC control both flow directions from the neutral point. Inside the card, a current-regulated, clocked output stage modulates coil energy so the solenoid receives a constant mean current even when the supply voltage fluctuates. Static deviation is kept within ±1% hysteresis, minimizing deadband in valve movement and supporting consistent control near the commanded position. Dynamic behavior includes a rise time of 60 ms for a full-scale step and a fall time of 70 ms. These response times are suitable for medium-speed hydraulic axes that require controlled changes without abrupt valve movement.
The board measures 79 × 85.5 mm, allowing it to be stacked in a standard Eurocard frame while maintaining a compact installation footprint. The amplifier is designed for the 2FRE Size 6 two-stage flow-control valve, supplying the regulated coil current required to position the valve accurately. The supported valve provides a hydraulic capacity of 60 L/min at a line pressure of up to 210 bar. Screw terminals provide secure field connections for the power, control, and valve conductors, making the individual circuits accessible within the enclosure. The board maintains its intended operating performance at ambient enclosure temperatures of up to +50 °C.
