Product Description:

The VT-UK2-3X/VT17115A/U173 is a plug-in analog interface card built by Bosch Rexroth Indramat within the VT-UK2 Universal Cards series. It occupies a single rack slot and forms the link between external transducers, command potentiometers, and the proportional or servo amplifiers that regulate hydraulic motion. This type of card conditions low-level analog signals so the connected hydraulic electronics receive stable reference and feedback values during closed-loop operation. By housing precision operational circuitry on a removable board, the card supports calibration or signal-conditioning updates without disturbing the surrounding control hardware.

As a Eurocard module measuring 160 mm high and 100 mm wide, the board matches the mechanical outline used by rack assemblies in industrial control cabinets. Electrical connection is made through the backplane via the DIN 41 612 interface, and its blade contact style provides a broad mating surface that minimizes insertion force while keeping contact resistance low over repeated cycles. These sizing and connector conventions keep installation consistent across different cabinet layouts. The standardized profile also allows predictable airflow around the components, which helps the precision amplifiers maintain thermal stability during continuous operation.

Conformance to DIN 41 494 sets the position of the guide rails and ejector handles, so the module remains seated firmly even when machinery vibrates. Internally, the circuitry is powered from a regulated 10 V rail that feeds the input stages and supports a balanced ±10 V signal swing. Each of the 6 onboard operational amplifiers can source up to 5 mA, which is sufficient for feedback loops that use low-impedance transducers or small pilot valves. This combination of channel count, current capability, and fixed supply level lets a single card serve one hydraulic axis while keeping diagnostics straightforward.
