For closed-loop hydraulic/electro hydraulic drive applications, VT-HACD-1 digital amp facilitates programming of pressure, flow, and positional functions. It accepts analog voltage/current and digital SSI or incremental feedback, with algorithms optimized for controlling hydraulic axes. Pre-programmed for various servo and proportional valves, card includes 32 predefined function blocks. It can also be used as command value generator for processing and scaling signals.

The VT-HCD-1 can be used as either a closed-loop control card or as a command-value generator.

For many closed-loop hydraulic-drive applications, it's now easier to program pressure, flow, and positional functions thanks to Rexroth's VT-HACD-1 digital amplifier. It accepts both analog voltage/current and digital SSI or incremental feedback, with algorithms optimized for controlling hydraulic axes. The card is pre-programmed for a variety of servo and proportional valves and includes 32 predefined function blocks to allow sophisticated control. It supports six software-switchable analog inputs, three switchable analog outputs (one switchable), eight programmable digital inputs, and seven configurable digital outputs. The VT-HACD-1 can also be used as a command value generator for processing and scaling signals.

Packaged in a standard Eurocard format, the VT-HACD-1 offers an alphanumeric display, pushbuttons for entering command values and for diagnostics, status LEDs, analog test jacks, and a serial interface for attaching a PC for programming with Rexroth's Windows-based BODAC digital-axis-control software. The card also supports the CANopen fieldbus for simple connectivity to controllers.
