Product Description:
The VT-UK2-3X/VT11985A/U152 is an electronic interface card manufactured by Bosch Rexroth Indramat for the VT-UK2 Universal Cards series. Intended for industrial automation panels, the board conditions low-level sensor signals and drives proportional valves by generating precise reference voltages and currents. Its Eurocard footprint supports quick slide-in mounting within standardized subracks, and the unit can serve as a bridge between transducers, controllers, and power stages in hydraulic or motion-control loops. By occupying only a single slot, it conserves cabinet space and provides flexible configuration options across multiple control axes. This makes it suitable for analog control paths that require stable signal transfer between field devices and higher-level electronics.
The board conforms to the Eurocard outline, giving it a physical height of 100 mm and a length of 160 mm. These dimensions follow the DIN 41 494 printed-circuit standard, which sets hole patterns and guide-rail clearances so multiple cards can share a common 19-inch subrack. The format also allows the card to fit standard guide rails and backplanes used in modular control racks. Signal and power lines exit through a rear-edge Blade Connector, allowing quick removal without disturbing front-panel wiring. A stabilized reference applied at the input feeds trimming networks, and five null-point potentiometers allow sensor offsets to be corrected during setup.
The mating backplane connector follows the DIN 41 612 layout, matching the male blade on the card. Internally, 6 precision operational amplifiers provide buffering, inversion, and gain functions, enabling linear signal conditioning without external stages. After processing, the board delivers an output voltage of 10 V at up to 5 mA, which is suitable for command inputs on proportional valve electronics and servo controllers. Because the input and output ranges are identical, closed-loop systems can use symmetric scaling, and calibration remains straightforward during normal adjustment. This arrangement helps preserve predictable response in feedback circuits that use the same nominal range for incoming and outgoing analog values.
