Product Description:

The VT-HACD-DPQ-2X-V1-1-C-0 is a plug-in digital axis controller manufactured by Bosch Rexroth Indramat within the VT-HACD Digital Axis Controllers series. Installed in hydraulic or electro-hydraulic motion systems, this card regulates position, velocity, and pressure loops by exchanging signals with proportional valves and higher-level PLCs. Its design places the required I/O, signal conditioning, and fieldbus connectivity on a Eurocard that slides directly into a backplane, which helps simplify cabinet wiring in industrial automation cells.

This controller operates from a nominal supply of 24 VDC, and it draws a steady 150 mA to power its microprocessor, A/D converters, and onboard reference circuitry. Field wiring is handled through a 64-pole male DIN 41612 Design G connector, allowing command, feedback, and enable lines to pass through a single backplane socket. For distributed architectures, a CANopen bus interface supports cyclic data exchange with multiple nodes, while the service port uses RS232 for setup and diagnostics. Reference commands are generated internally and delivered as voltage or current signals to the valve electronics, which keeps controller logic isolated from load-bearing power stages.

The card communicates with external SSI transducers over an RS485 channel and links to local expansion modules on a rack bus that can extend up to 280 m without repeaters. Overcurrent protection is provided by a 4 A time-lag fuse mounted on the front, and the reference stages accept a maximum differential of ±10 V to stay within calibrated limits. Physical dimensions of 100 × 160 mm and a front plate height of 128.4 mm conform to IEC 60297 sub-rack layouts, while the unit's 0.2 kg mass minimizes loading on card guides. The regulated supply window from 21 V to 30 V supports stable operation even when the plant's 24 V rail experiences acceptable dips or surges.
