Product Description:
The VT-HACD-1-12/V0/1-0-0 is a plug-in digital axis controller from the Bosch Rexroth Indramat VT-HACD Digital Axis Controllers series. Intended for mounting in Eurocard racks, the unit supervises closed-loop position, velocity, and pressure tasks in hydraulic drive assemblies. By sampling feedback transducers and issuing proportional commands to servo valves, the card functions as the central motion processor inside an industrial automation cabinet. This arrangement allows the controller to coordinate hydraulic motion while exchanging operating data with connected control equipment.
The controller provides 6 analog input channels that accept voltage or current signals from pressure or position sensors, while 3 analog outputs deliver reference values to external valve amplifiers. Discrete interfacing is handled by 9 digital inputs for mode selection and interlocks and 8 digital outputs, each sourcing up to 30 mA for status signaling or solenoid actuation. A scan time of 2 ms ensures that these input and output paths are updated fast enough for medium-bandwidth hydraulic loops. Communication with supervisory PCs is available through an RS-232 D-Sub port, and an incremental encoder port accepts position feedback. A 4 A time-lag fuse provides protection against excessive current. In standby mode, the electronics draw 250 mA from the supply rail.
The board measures 100 × 160 mm and mounts behind a 128.4 mm front plate that carries LED indicators and the RS-232 socket. A 64-pole DIN 41612 male edge connector mates the card to the rack, supplies the logic with a nominal 24 VDC, and connects the card to the local bus. This bus can span 280 m and address as many as 32 stations. The encoder interface accepts count streams up to 100 kHz, allowing high-resolution scales to operate without losing edge data. The controller has an overall mass of 0.2 kg, which reduces the mechanical load placed on the rack and card guides. Its compact Eurocard layout also keeps the communication socket and status indicators accessible from the front of the cabinet.
