Product Description:

The VT-UK2-3X/ES-E24-A009/U44 is a signal conditioning card from the VT-UK2 Universal Cards series manufactured by Bosch Rexroth Indramat. Designed for insertion into modular control racks, it provides analog and logic processing blocks that simplify customization of hydraulic and motion control loops in industrial automation equipment, especially where compact Eurocard modules are preferred. I/O lines are routed through a 32/64-pin DIN 41612 Form C/D connector so the backplane maintains signal integrity. The card is suited for cabinet-based systems that need signal scaling, switching, and conditioning within a compact plug-in format for analog interface work.

This board follows the standard Eurocard footprint with 100 x 160 mm overall dimensions, enabling direct placement in 3U frames. The analog section references a stable 10 V rail, and the same magnitude is reproduced at the buffered output, where the card can deliver 10 V and 5 mA to servo valves or drives. Relay interfaces actuate once control voltage rises into the +17 to +28 V window, giving galvanic isolation between field devices and the logic layer. This arrangement lets the module pass conditioned command signals to connected devices without placing the full load on the upstream control stage.

The card provides calibration flexibility through 5 null-point potentiometers, allowing individual stages to be zeroed without external resistors when temperature shifts introduce offset. Signal processing is handled by 6 operational amplifiers that can be assigned to proportional, integrating, or differential roles as needed. Jumper links select one of four functional blocks, inverter, Schmitt trigger, summing amplifier, or differentiator, so the same hardware supports inversion, threshold detection, summing, or edge-emphasis tasks in different control circuits. This helps the module adapt to different loop structures without changing the board format or adding separate signal-conditioning cards in the rack.
