Product Description:

The VT-UK2-3X/VT4333/U142 is an interface board produced by Bosch Rexroth Indramat within the VT-UK2 Universal Cards series. It is installed in standardized rack systems to relay analog process signals, bias reference voltages, and small actuator currents between motion controllers and proportional valves. By using the card, machine builders get a compact way to distribute conditioned feedback to centralized drive electronics without dedicating separate point-to-point wiring.

Mechanically, the module follows the Eurocard profile, giving predictable mounting hole positions and uniform insertion depth in 19-inch subracks. Its overall depth of 160 mm corresponds to the long format of DIN 41494, while the front panel spans 100 mm, letting the board occupy a single rack slot so adjacent modules retain standard air gaps. All signal and supply lines pass through a rear edge connector that follows DIN 41612, and this standardization simplifies wiring harnesses because the mating female connector is already integrated into most industrial backplanes. These dimensional and connector choices keep installation consistent across rack systems and help maintain organized cabinet wiring in production lines.

Functionally, the card integrates 6 operational amplifiers, enabling differential gain stages, summing nodes, or active filtering on each channel as required by hydraulic servo loops. Each amplifier is powered from a reference rail of 10 V that enters the board through the backplane, and it can deliver up to 5 mA per output without saturating. That output level is sufficient to drive valve electronics or transducer feedback lines over short distances. The outputs appear at the rear blade contacts of the male connector and present a nominal 10 V swing referenced to system ground. By concentrating these low-level analog blocks on one pluggable board, control cabinets can centralize calibration while leaving higher-power actuation to downstream modules.
