Product Description:
The VT-HACD-1-1X-V0-1-P-0 is a plug-in digital axis controller card produced by Bosch Rexroth Indramat within the VT-HACD Digital Axis Controllers series. Installed in a 19-inch rack, the board supervises motion axes by reading sensor feedback, scaling command references, and forwarding control signals to external valve amplifiers. In automated machinery, the card forms the core of closed-loop positioning systems, linking field devices to higher-level PLC or CNC platforms for precise hydraulic or electric drive regulation. This arrangement allows axis processing to remain inside the control rack while the power stage is handled by separate external amplifier hardware.
Control electronics are powered from a regulated 24 VDC logic rail, keeping internal circuits active while field wiring is serviced. The module accepts 6 analog inputs for pressure, position, or speed transducers, and it monitors machine states through 9 digital inputs. All I/O reaches the board through a 64-pin DIN 41612 Form G backplane connector that mates with standard Eurocard cages. For distributed control, cyclic process data is exchanged over PROFIBUS DPV0, while setup and diagnostics use the front-panel RS232 service port. Because the card has no on-board valve output stage, it delivers conditioned command signals to external amplifiers, which shifts most power dissipation away from the control rack.
The controller offers 3 analog outputs that supply redundant command channels or retransmit feedback to auxiliary drives. A conversion cycle completes every 2 ms, matching typical hydraulic loop bandwidths without aliasing and allowing fast response to changing machine conditions. Signal scaling is centered on a ±10 V reference, which keeps bipolar command behavior symmetrical for proportional valves. A small front display provides menu-based parameter access, and total idle draw stays below 250 mA, so a 4 A slow-blow fuse protects the logic supply without nuisance trips. With no valve output stage present, thermal load is minimal, and convection through the rack slots is sufficient for cooling.
