Product Description:

The VT-UK2-3X/VT4451/U50 is a universal signal-conditioning board produced by Bosch Rexroth Indramat for the VT-UK2 Universal Cards series. Installed in control racks, the card translates low-level sensor data into standardized voltages for industrial automation controllers and valves. By occupying a single Eurocard slot, it serves as a compact analog processing element that simplifies field wiring and parameter adjustment inside hydraulic or motion-control cabinets. That role helps isolate sensitive control inputs from raw field signals that may require scaling or offset correction before they reach the rest of the system.

Physically, the board follows the Eurocard format and measures 100 x 160 mm, so it fits standard 3U rack guides without additional spacers. Signal and power lines pass through a DIN 41612 backplane interface on a Blade Connector, allowing quick installation while maintaining reliable contact resistance. The on-board circuitry uses a 10 V supply delivered through the backplane to feed reference networks and active devices. Using the rack connection for both power and signal routing reduces front-access wiring and keeps the card edge accessible for service in densely populated control cabinets.

Signal processing is handled by 3 double op-amps, giving a total of 6 operational amplifiers that can be arranged as differential inputs, integrators, or active filters depending on jumper positions. Calibration is adjusted through 5 potentiometers, each using a null-point design to correct drift without changing gain. The conditioned channel can source up to 5 mA, which is enough to drive valve electronics while holding the output at the card's fixed 10 V span. Soldered junctions throughout the board hold component leads securely and help maintain low contact resistance under vibration, and the layout supports offset and response adjustments without requiring external signal-conditioning hardware.
