Product Description:

The VT-HACD-DPC-1-2X-V0-1-0-0 is a plug-in digital axis controller card manufactured by Bosch Rexroth Indramat for the VT-HACD Digital Axis Controllers series. It is mounted in a 100 × 160 mm Eurocard frame. It conditions analog setpoint, feedback, and encoder signals so a hydraulic or electro-hydraulic drive can be closed-loop regulated from a PLC or motion kernel.

The card is powered from a nominal 24 VDC supply, and its power section tolerates drops to 21 V and surges up to 35 V without losing logic integrity. It samples all control channels every 2 ms, so velocity or position deviations are detected quickly. An incremental encoder input is accepted up to 100 kHz, allowing high-resolution position tracking on fast axes. The first analog output can deliver up to 10 mA, which is enough to drive most servo valves directly; this channel offers a 1.25 mV voltage step for fine adjustment, while the second output provides 10 mV resolution when a wider span is permitted. Voltage inputs are buffered by 100 kΩ impedance to avoid loading external transducers, and current inputs see 100 Ω so 0–20 mA loops are interpreted accurately. A ±10 V reference is available for sensor excitation, and total board consumption stays near 150 mA during steady operation.

Up to 30 mA can be sourced by each digital output, which is adequate for relay coils or optical isolators, and overload protection is ensured by a 4 A slow fuse on the supply line. With a 100 kΩ input path, the voltage channels remain resistant to noise over long cables, and the controller can be sited away from the motion frame while still maintaining deterministic updates across a local bus reach of 280 m. Current input resistance of 100 Ω makes scaling straightforward when shunt resistors are already embedded in field devices.
