Product Description:
The VT-VPCD-1-15/V0/1-0-1 is a plug-in electronic drive card manufactured by Bosch Rexroth Indramat for the VT-VPCD Drives series. Installed in a standardized rack, the card regulates proportional valves by converting command signals from the machine control into conditioned reference voltages and currents suitable for hydraulic actuation. In industrial automation, it connects low-level analog I/O to valve coils, allowing pressure or flow loops to be closed directly at the machine without external signal conditioning. This arrangement supports precise hydraulic control while reducing the need for separate interface modules between the controller and valve assembly.
The board operates from a 24 V DC supply and draws up to 3.5 A, so the cabinet power rail must provide sufficient current. The integrated output stage can source or sink an analog signal of ±10 V. A step size of 10 mV with 11-bit resolution allows the valve spool to be positioned precisely across its operating range while driving loads down to the specified minimum of 1 kΩ. Incoming current commands pass through a 100 Ω shunt and are digitized with a 5 µA resolution at 12 bits, whereas voltage commands use a 100 kΩ input impedance that minimizes loading on upstream controllers. The card also accepts either a 30 mA reference current or a ±10 V reference voltage, providing compatibility with various motion and process controllers.
The control logic cycles every 2 ms, providing rapid updates for pressure and flow regulation. Parameter data can be exchanged over the local bus across distances up to 280 m, allowing remote valve islands to receive synchronized control updates. A service port with an RS-232 interface supports configuration and diagnostic access. The Eurocard measures 100 × 160 mm and has a 128.4 mm front plate, allowing it to fit standardized rack assemblies. The card weighs 0.2 kg, adding little mass to densely populated backplanes. Its plug-in format allows the card to be inserted or removed without disturbing the wiring of adjacent modules.
