Geo Brick LV
TM
Multi-axis controller with Low Voltage (12V to 60V) amplifiers
PRODUCT DESCRIPTION:
The Geo Brick LV
TM
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!
