Product Description:

The VT-UK2-3X/VT13981A/U101 is a plug-in universal signal conditioning card produced by Bosch Rexroth Indramat for the VT-UK2 Universal Cards series. Installed in control racks, the card provides analog scaling and feedback processing so hydraulic or motion controllers can acquire sensor signals, create reference voltages, and distribute standardized outputs. By occupying a single Eurocard slot inside an automation cabinet, it simplifies retrofits where multiple discrete conditioners would otherwise be required. Within hydraulic servo loops, the card’s operational amplifiers supply gain stages that help keep valve position or pressure stable and keep low-level signals usable for closed-loop control.

The physical layout follows the 100 x 160 mm profile, which matches the height and depth of standard 3U sub-racks. This footprint matches the Eurocard format, allowing the module to slide into guide rails without custom hardware. Compliance with DIN 41 494 keeps pin allocation and board thickness consistent with widely used industrial practice. Field wiring terminates on a front-edge Blade Connector, and mating backplane sockets follow the DIN 41 612 pattern so power and signal pins line up consistently from one card position to the next.

In operation, the card receives a reference level of 10 V, routes it through six precision stages, and delivers up to 5 mA per channel to external loads while maintaining a mirrored output swing for feedback lines. The presence of 6 integrated operational amplifiers allows differential inputs, gain blocks, and active filters to be combined on one board. This arrangement lets one module handle several analog conditioning tasks close to the controller and reduces the need for separate interface boards in the same rack. The board can therefore support reference generation, buffering, and signal shaping without requiring additional standalone modules.
