The Geo Brick LVTM is Delta Tau’s latest addition to the Brick family of multi-axis ‘Smart Amplifiers’. The ‘LV’ combines the power of Delta Tau’s Turbo PMAC2 controller with MOSFET motor amplifiers in a sleek industrial package.

The Turbo PMAC2 ‘processing engine’ provides for a full-featured motion controller with Ethernet, USB, and RS232 communications. Each ‘LV’ axis includes incremental encoder inputs for position feedback and optically isolated motor I/O flags (Home, Limit +/-). Standard ‘LV’ I/O for machine control includes 16 optically isolated inputs and 8 fused protected outputs.

The ‘LV’ utilizes Delta Tau’s Direct Digital PWM technology to provide superior position/velocity control of Brushless (linear & rotary), Brush, and Stepper motors. Available in 4 or 8 axis versions, the ‘LV’ delivers 5A continuous current (15A peak) with a voltage range of 12 to 60 volts per axis.

The ‘LV’ supports applications ranging from stand-alone to real-time PC based. The integrated controller/amplifier reduces wiring costs, while increasing system robustness. For lower voltage/current applications the ‘LV’ is the Delta Tau solution that you have been waiting for!
