Product Description:
The VT-HACD-1-14/V0/1-0-0 belongs to the VT-HACD Digital Axis Controllers series manufactured by Bosch Rexroth Indramat. Installed in a control cabinet, this Eurocard-format module supervises hydraulic axes by processing sensor feedback, generating command values, and exchanging set points with higher-level PLCs. Its purpose in an industrial automation cell is to close the motion loop for proportional or servo valves so that position, velocity, or pressure follows the programmed profile with minimal error. That control role allows the module to manage closed-loop hydraulic motion without placing all signal-processing tasks on the PLC.
The controller accepts 6 differential analog inputs for transducers such as LVDTs or pressure sensors and provides 3 analog outputs that drive external setpoint channels. A fixed sampling interval of 2 ms lets the internal DSP update control algorithms fast enough for most hydraulic positioning tasks, while the incremental encoder channel can count edges up to 100 kHz to register rapid axis movement accurately. Power is supplied at 24 VDC, and the circuit remains functional between 21 V and 35 V, enabling operation on common machine power buses. ±10 V reference levels are available for standardized signal scaling. Configuration or diagnostics are handled through an RS-232 port, and there is no fieldbus interface, so network communication must be arranged through the host PLC. The board omits a valve output stage, which means the final power amplifier is located in a separate module.
A front-mounted 4 A slow-blow fuse protects the supply path, and quiescent consumption is limited to 250 mA when outputs are idle. The board weighs only 0.2 kg, which reduces load on card retainers and keeps handling simple during installation. Its outline of 100 × 160 mm follows the DIN 41494 standard, letting it slide into a 19-inch sub-rack beside other automation cards. The standardized Eurocard size also helps the module fit neatly into dense rack layouts used for hydraulic control hardware. This format is commonly used where multiple motion and I/O cards share one enclosure.
