C11G (Rev.7.1) User Manual
• Built-in Variable Speed Control.
It has an optoisolated analog 0-
10VDC output that will convert a step
signal into an analog signal that can
be used to command a commercial
VFD. This analog can be adjusted
using on-board potentiometer, so this
board can be adjusted to other
voltages.
• Two Solid State Relay with NO and
NC positions.
Mechanical relays are very flexible
because they can be used for AC or
DC and come with NO and NC
(Normally Open
Closed) positions.
• Status LEDs on all inputs and
output connections.
No more guessing. You can SEE all
your signals. Save valuable time and
brainpower for CNCing. To avoid
remaining current to the main load
(driver or other device), all the
indicator LEDs

drive de output.
• Output pins 1, 2, 3, 4, 5, 6, 7, 8, 9,
14, 16, 17.
• Input pins 10, 11, 12, 13, 15.
• Input and output pins with close
by ground or +5vdc connections
• The common terminal to pins 2-9
can be ground or +5vdc. Forget
about grounding problems. Easily
connect your pin by using your close

an electronics expert to ground all
