Product Description:

The VT-VPCD-1-14/V100/1-0-1 is a plug-in control card produced by Bosch Rexroth Indramat for the VT-VPCD Drives series. Inserted into a backplane rack, the board conditions analog command values and distributes them to proportional valve electronics so flow or pressure loops can be driven directly from a central controller. It serves as an interface between higher-level control signals and valve amplifiers in hydraulic axes that require stable regulation. By executing these low-level tasks on board, the card increases channel density and simplifies wiring inside automated hydraulic systems.

The card is powered from a stable 24 VDC supply and samples its input channels on a 2 ms cycle, which is fast enough for most motion and pressure loops. Configuration and diagnostics can be accessed through a built-in RS-232 port, allowing parameter changes without removing the module. The analog output stage delivers a bipolar range of ±10 V with a resolution of 10 mV, which supports smooth spool positioning on proportional valves when the connected load is at least 1 kΩ. Voltage inputs present 100 kΩ of resistance, current command channels are terminated by 100 Ω, and the stage keeps ripple within ±25 mV. This arrangement lets the module process both voltage and current commands with predictable loading at the inputs.

The Eurocard outline measures 100 × 160 mm and mates with a 64-pole DIN 41612 G backplane connector for straightforward rack installation. Peak consumption stays within 3.5 A, and the card can accept up to 30 mA of reference current without saturating its converters. The matching 5 µA input resolution supports fine setpoint trimming during analog control, and the compact format leaves room for multiple cards in a shared chassis. Despite the full analog and serial circuitry, the assembly weighs only 0.2 kg, which minimizes stress on card guides and supports dense stacking in multi-axis control cabinets.
