Product Description:

The VT-UK2-3X/ES-E61-A204/U209 is a plug-in conditioning card produced by Bosch Rexroth Indramat for the VT-UK2 Universal Cards series. Deployed in industrial automation racks, the module shapes analog command and feedback signals for hydraulic or motion controllers, allowing standardized installation within 19-inch subracks. By conditioning low-level electrical signals before they reach the main control stage, it helps connected hydraulic and motion systems respond more consistently during operation.

The board follows the Eurocard layout, and its 160 mm height with a 100 mm width matches the mechanical envelope of DIN 41494, so it slides directly into card guides without additional spacers. Connections to the backplane are made through a DIN 41612 interface in a blade connector style, which supports stable mating cycles in environments subject to vibration. Signal processing resources are arranged across several function blocks implemented with low-noise operational amplifiers, while supply pins accept a regulated reference for low-level circuitry. The card’s fiberglass substrate and conformal coating permit operation in control cabinets where temperature and humidity are managed by the main enclosure.

Application flexibility is provided by 6 operational amplifiers that can be wired as differential inputs, inverting stages, or integrators depending on jumper settings. Each channel is powered from a 10 V rail and can source up to 10 V / 5 mA, allowing it to drive valve electronics or sensor loops directly. For status signaling, an onboard relay energizes when a separate excitation between +17 to +28 V is present, which provides galvanic isolation from the analog domain. The module withstands storage from -20 °C to +70 °C without drift, so spare units kept on the shelf remain within tolerance until installation.
