VT 11131-12a
The Bosch Rexroth Indramat VT 11131-12a is a precision servo amplifier from the VT Servo Amplifiers series, designed for demanding industrial automation applications. It operates on a nominal 24 VDC +40%/-10% (21–35 V) supply and maintains stable performance under fluctuating power conditions. Boasting a low power consumption of ≲30 VA and a peak current draw below 1.3 A, the VT 11131-12a delivers reliable drive performance for compact servo motor systems.
Featuring a versatile control interface, the VT 11131-12a accepts a clock-pulse frequency input of 170–200 Hz (±15%) and an analog command voltage range of ±10 V. Its high input impedance of >>50 kΩ<< ensures minimal loading on upstream controllers and precise signal fidelity. The amplifier’s ramp time is adjustable between 50 ms and 5 s, enabling both rapid dynamic response and smooth velocity transitions. Connectivity is provided via 12 screw terminals, simplifying wiring and reducing installation errors.
Engineered for seamless integration, the VT 11131-12a mounts on a Carrier rail TH 35–7.5 (EN 60715) and fits within dimensions of 40 × 79 × 85.5 mm, with a lightweight design of 0.16 kg. It operates reliably in ambient temperatures from 0 to +50 °C, ensuring durability in standard industrial environments. The compact form factor and robust voltage tolerance enhance system uptime and scalability. Employing this amplifier improves energy efficiency, reduces heat generation, and delivers precise motion control in modular production lines and automated machinery.
