Product Description:
The VT 12302-3X is a plug-in servo amplifier card produced by Bosch Rexroth Indramat for the VT 1600 Servo Amplifiers series. Installed in a standardized Eurocard rack, it modulates drive current according to control commands. This regulated current allows automated machinery to maintain accurate speed and position profiles during production cycles.
The card footprint measures 100 × 160 mm, a format that matches DIN 41494 subracks and simplifies rack installation without requiring wiring changes. Signal and power lines enter through a 64-pole female DIN 41612 G connector; this multirow interface separates sensing, logic, and output paths to minimize crosstalk. Internal traces are rated for a continuous bus draw of 2.5 A, while the dedicated z-row supply pins—z2, z4, z6, z8, z30, and z32—support up to 4 A each for peak actuator demands. Output stages must not exceed a terminal potential of 30 VDC, keeping clearance distances and component stress within safety margins. Even-numbered contacts on rows F, D, B, and Z follow the published pin assignment, allowing encoder feedback, enable lines, and diagnostic connections to use standard harnesses.
A front plate width of 8 TE provides sufficient panel space for test points and status LEDs while preserving rack density. The enclosure is fabricated from sheet steel with colorless passivation, providing natural conductivity for shielding and resistance to surface oxidation. Once mounted, the assembly has an IP20 protection rating, which guards against finger contact with terminals while permitting cabinet airflow. With a mass of 1.250 kg, the board places minimal load on card guides and backplane connectors, allowing multiple amplifier channels to be installed in a control enclosure.
