Product Description:
The VT-VPCD-1-1X/V100/1-0-1 is a plug-in drive control card developed by Bosch Rexroth Indramat for the VT-VPCD Drives series. The board occupies one slot in a control rack and interfaces with external sensors and actuators through standardized voltage and current channels. In industrial automation, it translates low-level setpoints from a PLC into proportional commands suitable for servo drives, valves, or other motion elements, allowing closed-loop control with short internal processing cycles.
The card operates from a logic supply of 24 VDC, which simplifies integration with typical machine control buses. Under maximum load, its electronics draw up to 3.5 A, a figure used when sizing cabinet power distribution and fusing. Internal signal processing is cyclical, and each scan is completed in 2 ms, so updated control values are sent to the outputs very quickly. The analog output stage converts digital words to voltage with a step size of 10 mV (11-bit), giving fine resolution across the available range. On the feedback side, the current input channel resolves 5 µA (12-bit), enabling the controller to detect small variations in a 4–20 mA loop without external amplifiers. A built-in RS-232 port allows parameter adjustment from a laptop.
The analog channels use a symmetrical span of ±10 V, letting the module generate positive or negative drive commands without additional level shifting. A voltage input resistance of 100 kOhm minimizes loading on upstream signal sources, while the output buffer operates linearly with connected loads of at least 1 kOhm. With a mass of only 0.2 kg, the Eurocard format (100 × 160 mm) can be inserted into the rack without heavy tooling. Additional features include a 30 mA reference supply for external potentiometers, 0.15% current-input leakage, and a 100 Ohm shunt for loop impedance.
