J8: Extra General Purpose I/O (Optional)
General purpose I/O is available on the Brick Motion Controller. All I/O is electrically isolated from the
drive. Inputs can be configured for sinking or sourcing applications. All Inputs are 12-24VDC. All
Outputs are 24V nominal operation, 0.5A maximum current. Outputs are robust against ESD and
overload.

*For sinking outputs, connect the COM_EMT (pin11) line to the Analog Ground of the Power supply and the outputs to
the individual plus output lines, e.g. GPO1+
**For sourcing outputs, connect the COM_COL (pin29) line to 12-24V and the outputs to the individual minus output
lines, e.g., GPO1-
Do not mix topologies, i.e., all sinking or all sourcing outputs. If the common emitter is used, the common collector
should be unconnected. Conversely, if the common collector is used, the common emitter should be unconnected.
