The VT-HACD-1 digital amplifier makes it easier to program pressure, flow and positional functions for many closed-loop hydraulic-drive applications, says the vendor.
The VT-HACD-1 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, eight programmable digital inputs and seven configurable digital outputs. 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.
