Product Description:

The VT-HACD-DTC-12-V2-1-C-0 is a plug-in digital axis controller produced by Bosch Rexroth Indramat for the VT-HACD Digital Axis Controllers series. Supplied on a Eurocard, the module is inserted into a control rack where it generates analog setpoints and acquires sensor feedback to regulate hydraulic or electromechanical axes. Within an automated cell, it provides closed-loop position, velocity, and pressure control, relieving the central PLC of time-critical motion tasks.

This board operates from a single 24 VDC logic supply that is limited to 150 mA maximum, keeping panel power demand low. Its internal processor refreshes all control loops every 2 ms, so valves and drives receive timely updates under dynamic load changes. Network traffic is handled through the integrated CANopen interface, allowing parameter access and diagnostics from fieldbus masters. Precise command generation is achieved by the Ao1 channel, whose converter provides a resolution of 1.25 mV (14-bit) across the ±10 V span. The board routes outputs through a 64-pin DIN 41612 Form G connector and can sink up to 30 mA on each digital output. Mechanical dimensions follow the 100 × 160 mm Eurocard outline, and a 128.4 mm front height fits standard subracks. A small front display shows setpoints and status values during setup and operation.

For long backplane installations, the local system bus reaches up to 280 m without repeaters, while host PCs can still connect directly through the built-in RS-232 port for legacy tools. The second analog channel delivers a symmetrical output of ±10 V, and the same range is available internally as a reference for external electronics. Overcurrent events on the supply rail are limited by a board-mounted fuse rated at 4 A slow-blow. Despite these protective features, the card weighs only 0.2 kg, which minimizes load on retention clips.
