Product Description:

The VT-UK2-3X/SYV313-6310-B040-E61-R01/U147 is a plug-in control card produced by Bosch Rexroth Indramat for the VT-UK2 Universal Cards series. It is intended for rack-mounted hydraulic drive systems where modular analog processing is required. Within an automation rack, this card supplies summing, differential, Schmitt trigger, inverter, and regulator functions so that motion valves or pressure regulators receive conditioned signals without adding discrete boards. Its Eurocard format allows direct insertion into standardized backplanes, making the product a compact signal-conditioning element for industrial hydraulic controls.

The board follows the Eurocard mechanical standard and occupies a 100 x 160 mm slot, so cabinet depth and height can be predicted accurately during panel layout. Signal and power reach the circuitry through a DIN 41 612 backplane connector that may be supplied in C or D form with 32 or 64 contacts. These contacts are arranged in a blade connector to speed installation and removal. Three dual operational-amplifier packages provide six linear stages, and five null-point potentiometers provide separate offset adjustments for the individual amplifier sections. All internal links are made by soldered junctions that maintain low impedance over temperature and vibration. Because the core functions of regulation, inversion, Schmitt triggering, summing, and differential processing are implemented on one card, only a single slot is used when building complex hydraulic controllers.

The analog sections operate from an input reference of 10 V, ensuring compatibility with typical transducer outputs. The buffered output section sources up to 10 V; 5 mA, so downstream valve electronics receive a stable command. Coil actuation for external relays can be driven directly because the call-up line supplies +17 to +28 V. Component ratings allow continuous service in ambient temperatures from 0 to +50 °C, matching most enclosed machine spaces. A set of three double op-amp packages and the five adjustable pots work together to keep drift and gain error within the limits needed for motion stability.
