VT-11023

The VT-11023 is a precision Servo Amplifier engineered by Bosch Rexroth Indramat within the VT Servo Amplifiers series to deliver reliable control in industrial automation environments. This compact unit accepts a Differential Input range of 0 to ±10 V; R = 50 kΩ and operates from a single Operating Voltage of +24 VDC +40% to −10%. Featuring an Oscillator Frequency of 5.8 kHz ±10% and a Ramp Time Range adjustable between 10 ms to 5 s, the VT-11023 precisely modulates valve spool movements. Weighing just 0.14 kg with compact Housing Dimensions of 40 x 79 x 85.5 mm, it supports straightforward integration into control cabinets and modular assemblies.

Technical capabilities of the VT-11023 include a robust Max. Current Consumption of 2 A and an Output Stage Solenoid Current/resistance capacity of Imax = 1.8 A; R = 5.4 Ω, enabling efficient drive of proportional valves and electromechanical actuators. The device sustains a Pulse Frequency of Up to ~1.5 kHz for high-resolution positioning signals and accommodates a Max. Stroke Of Transducer of 2.8 mm for precise feedback. Its release circuitry activates reliably between 8.5 V to 40 V, safeguarding solenoid de-energization under fault conditions. Electromagnetic shielding and filtering ensure Disturbance Resistance at Class 3 to prEN 50082 T2, maintaining signal integrity amid harsh electrical noise.

Operational features of the VT-11023 enhance system uptime and diagnostics. The amplifier’s rugged design performs continuously within a Permissible Operating Temperature of 0 to 50°C and can be stored between –25 to +85°C without degradation. Built-in cable break recognition and polarity safeguards protect both amplifier and actuator from wiring faults. The adjustable ramp generator, together with the oscillator and demodulator for inductive positioning signaling, optimizes dynamic response while minimizing overshoot and wear on hydraulic components.

Integration into existing automation setups is streamlined by the VT-11023’s standardized form factor and industry-proven interface. Its compact footprint and low mass simplify mounting on DIN rails or sub-plates alongside PLCs and safety controllers. Compatible with a wide range of Bosch Rexroth valves and control modules, the amplifier supports seamless interconnection via standard supply and signal cabling. The combination of precise control, robust disturbance immunity, and flexible supply tolerance makes the VT-11023 ideal for machine tools, packaging systems, and mobile hydraulic applications where performance and reliability are paramount.
