Product Description:

The VT-HACD-517-1X-V0-EFF00331 is a plug-in digital axis controller card manufactured by Bosch Rexroth Indramat for the VT-HACD Digital Axis Controllers series. Installed in a Eurocard rack, the board supervises hydraulic or electromechanical axes by processing sensor feedback and generating command signals to a connected valve amplifier or drive module. Its role in an automation cell is to provide closed-loop position, velocity, and force control, with parameter sets that can be adjusted through a serial link.

All real-time computations are executed every 2 ms, so the control loop responds with very little delay. Logic power is supplied at 24 VDC, and the board draws no more than 250 mA in standby to reduce cabinet loading. The board provides 6 differential analog inputs for sensor voltages referenced to ±10 V, allowing simultaneous monitoring of multiple pressure or position channels. Command values leave the controller through 3 analog outputs for valve drive or reference sharing. Discrete machine states are captured through 9 digital inputs, while actuator commands are issued on 8 digital outputs. A dedicated reference stage can source current for external potentiometers, and the digital outputs are suitable for low-power interface devices such as opto-isolators or relay coils.

The Eurocard format measures 100 x 160 mm, and it plugs into a 64-Pin DIN 41612 G backplane connector that carries all power and signal lines. For configuration and diagnostics, the front panel exposes an RS232 port, allowing parameter download without removing the board from the rack. An onboard slow-blow fuse rated at 4 A protects the auxiliary supply against wiring faults, and each digital output can sink or source up to 30 mA. That output level supports direct connection to low-power indicators and pilot devices. Total mass is 0.2 kg, so vibration loading on the carrier frame remains low even in mobile equipment.
