Product Description:

The VT-HACD-2-1X-V0-1-0-0 is a modular axis controller card produced by Bosch Rexroth Indramat for the VT-HACD Digital Axis Controllers series. Installed in a sub-rack, the card supervises hydraulic or electro-hydraulic axes by reading sensor signals, running closed-loop algorithms, and forwarding commands to external valve drivers. Within industrial automation, it bridges PLC-level sequencing and real-time motion requirements, providing position and force regulation for hydraulic cylinders and presses.

The card has 6 differential analog input channels for pressure, position, or velocity transducers, allowing multivariable feedback on one card. Control logic is powered from a single 24 VDC supply, which keeps cabinet wiring simple and isolates the low-level electronics from higher drive voltages. For setup and diagnostics, the front edge offers an RS232 serial port. Internal computation is synchronized to a 2 ms sampling time, so position loops can refresh 500 times per second, which is suitable for fast hydraulic axes. The card also has 8 debounced digital inputs for limit switches or start signals without additional interface modules.

The card provides 3 analog outputs that can generate ±10 V demand signals for external valve amplifiers. It also includes 7 programmable transistor outputs for on/off commands to pumps, solenoids, or indicator lamps. Mechanical integration follows the 100 × 160 mm Eurocard format with a 64-pin DIN 41612 type-G connector, so the board plugs directly into standardized backplanes and mates with adjacent controllers over the local bus, which may span up to 280 m. Despite the wide signal complement, the assembly weighs only 0.2 kg, easing strain on card guides and allowing dense rack layouts. A 4 A slow-blow fuse on the supply rail protects the circuitry from reverse connection or accidental short circuits without tripping upstream breakers.
