The Bosch Rexroth Indramat VT 11131-12a from the VT Servo Amplifiers series is a compact industrial amplifier that operates on 24 VDC +40%/–10% (21–35 V) and consumes ≤30 VA with a current draw of 1.3 A. Measuring 40×79×85.5 mm and weighing 0.16 kg, it mounts easily on a carrier rail TH 35-7.5 (EN 60715). The device accepts a clock-pulse frequency of 170–200 Hz (±15%), an analog command voltage of ±10 V with an input impedance of >50 kΩ, and offers a ramp time adjustable between 50 ms and 5 s, making it ideal for dense automation applications.
