Product Description:
The VT-HACD-3-23/E-I-00-000 is a single-axis controller card produced by Bosch Rexroth Indramat for the VT-HACD Digital Axis Controllers series. Installed in control cabinets, it supervises proportional or servo-hydraulic actuators by processing sensor feedback, generating valve commands, and managing closed-loop position or pressure tasks in industrial automation cells and test benches. Its modular Eurocard format allows direct mounting in Rexroth rack systems while keeping wiring distances short. The card also provides an onboard Ethernet interface for configuration and diagnostics from standard computers.
The electronic core is a 32-bit PowerPC processor that executes interpolation, PID algorithms, and safety checks within deterministic cycles. For cabinet installation, the module has an IP20 enclosure rating and draws only 200 mA from the 24 V backplane, so heat dissipation remains modest. Six analog input channels support current or voltage transducers. Their finest measurable step is 5 µA in current mode or 5 mV in voltage mode, and overall nonlinearity remains within ±0.25%. Nine digital inputs allow fast sequencing or limit detection without additional I/O boards. The reference supply provides +10 V for external sensors with a tolerance of ±25 mV, maintaining stable excitation for strain gauges and linear variable differential transformers.
Three analog output channels are provided, and channel 1 reaches a resolution of 1.25 mV, making it suitable for fine valve staging in hydraulic manifolds. Eight digital outputs can source up to 20 mA each, enabling direct control of indicator lamps or solid-state relays without intermediate amplifiers. The incremental encoder input accepts frequencies up to 250 kHz, so high-speed linear scales or servo encoders can be connected without losing edge information. An SSI port handles absolute feedback with a data width of 28 bits, supporting precise multi-turn position data. The Ethernet-equipped card has a total mass of 1,162 g, which limits the load placed on the rack and its supporting hardware.
