VT-SR2-13/0-60 by Bosch Rexroth Indramat

The Bosch Rexroth Indramat VT-SR2-13/0-60 proportional amplifier from the VT-SSPA Plugin Proportional Amplifiers series is a compact plug-in analogue device engineered for single and two-stage servo-valves. It offers reverse polarity protection on both supply and auxiliary lines up to 1 A and utilizes natural convection cooling. A front-panel zero point adjustment via R3 and an amplitude-adjustable dither signal via R7 ensure precise control, while the push-pull bipolar output stage delivers reliable valve currents of ±60 mA. The integrated enable circuit with LED indication supports safe operation, and optional modules include an adjustable P&D PID controller, a reserve relay, and a ±15 V voltage regulator. Suitable for valves such as 4WS2EM6, this IP00 amplifier requires external protection from contamination and mounts in a standard VT 3002 card holder.
